First 200 people get 20% off annual premium subscription.
In this video we'll explore the world's fastest improving new solar technology, and provide an exclusive peek inside the lab of a team working on this breakthrough material.
Imagine an inexpensive solution of perovskite crystals that can make a photovoltaic cell so thin, that just half a cup of liquid would be enough to power a house. A solar panel so lightweight, that it can be balanced atop a soap bubble. That is known as the holy grail of solar energy. So when will we see perovskite solar panels used for a solar power system for your home? Maybe sooner than you expect.
Currently, only 2% of global electricity comes from solar power. And 90% of that, comes from crystalline silicon-based solar panels, the dominant material technology.
While abundant, silicon has downsides related to efficiency, manufacturing complexity, and pollution that prevent it from being an absolute no brainer. Emerging thin films like perovskites present a bright future. Imagine solar cars like a solar tesla, solar yachts, or a solar plane.
Solar cell technologies can be classified into two categories, wafer-based or thin-film cells. Perovskites are the leading contender in emerging thin films. Topics covered in this video include applications, perovskite crystal structure, working principle of perovskite solar cells, efficiency limits, multi-junction solar cells, shockley-queisser limit, how solar works, solar simulator, band gap, manufacturing, vapor deposition, how solar panels are made, and the future of solar power.

[@bobsmith6544]

Did you notice the part about how they aren't as good as normal cells? LMFAO!

[@AnalystPrime]

@@bobsmith6544 People keep using "not as good" tech all the time. Like paying far more for maintenance and per mile just because ICE cars are little cheaper to buy and faster to refuel. These panels could deliver twice as much power as modern panels at far cheaper price, and because they can be lighter than the silicon panels they would also be cheaper to transport and easier to handle so even the most expensive part, the installation, could cost less. At lower price it is also viable to do things like putting panels on the walls or the less sunny side of the roof, so instead of paying $20k for a 10kW system you might get 25kW for $5k, at which price you would likely save money even if the panels had to be replaced every five years.

[@michaelmoorrees3585]

It all boils down to cost. If its cheap enough, then it will be like getting your house repainted. In the past few years, traditional silicon panels have gotten down to ~70 cents a watt at retail prices. That's only $7000 for a 10KW installation. if you're a DYIer, you are no longer looking a a $20K+ installation. Inverters are cheap, and if you use forklift deep cycle lead acids, you can build your own "power wall", without subsidizing Elon Musk's lifestyle.

Yeah, I wish this channel went more in depth on the drawbacks instead of only highlighting the pros. Luckily the CEO was transparent and not overly enthusiastic since there are a lot of challenges to getting this tech widely accepted and implemented. I shouldn't have to go to the comment section to learn that the stability issue is that the cells degrade significantly in a couple of days. I shouldn't have to go to Google to learn that viable perovskite cells rely on lead. Also, in the video the film is thin enough where it is tinted and not translucent. How can they achieve >30% efficiency when much of the light is getting through? Are all of the numbers touted in terms of materials needed and efficiency consistent or based on different specifically tailored conditions? This is the kind of video where I am just frustrated that the author went the "research stretching the truth to gain investors" route instead of piggybacking off of the CEO grounding the tech in reality.

@@johnpeters6147 The problem with PTF has been durability and deteriorating properties in real world use. This is something that we've been working on for over a decade and while there have been various different solutions, most of them take away from the properties that make PTF useful. Thus, any kind of method of reinforcing PTF makes them heavier, rigid, or more expensive. The lifespan being 5-20 times shorter counters the issue of resources used for production as well. We might get there some day, but PTF has a long way to go as a usable technology for any kind of hype to be built on it yet.

"Stability and Degradation: Perovskite solar cells have demonstrated competitive efficiencies with potential for higher performance, but their stability is quite limited compared with that of leading PV technologies: They don’t stand up well to moisture, oxygen, extended periods of light, or high heat. To increase stability, researchers are studying degradation in both the perovskite materials and the contact layers. Improved cell durability is paramount for the development of commercial perovskite solar products. Despite significant progress in understanding the stability and degradation of perovskite solar cells, current operational lifetimes are not commercially viable. Mobile markets may tolerate a shorter operational life, but stability during storage (prior to use) is still a key performance criterion for this sector. For mainstream solar power generation, technologies that cannot operate for more than two decades are unlikely to be viable regardless of other benefits. Early perovskite devices degraded rapidly. A few years ago, typical perovskite devices would degrade within minutes or hours to non-functional states. Now multiple groups have demonstrated lifetimes of several months of operation. For commercial, grid-level electricity production, SETO is targeting an operational lifetime of at least 20 years, and preferably more than 30 years. The perovskite PV R&D community is heavily focused on operational lifetime and is considering multiple approaches to understand and improve intrinsic and extrinsic stability and degradation. Efforts include improved surface passivation of absorber layers; alternative materials and formulations for absorber layers, charge transport layers, and electrodes; and advanced encapsulation materials and approaches that mitigate degradation sources during fabrication and operation. One issue with assessing degradation in perovskites relates to developing consistent testing and validation methodologies. Research groups frequently report performance results based on varied test conditions, including variability in encapsulation approaches, atmospheric composition, illumination, electrical bias, and other parameters. While such varied test conditions can provide insights and valuable data, the lack of standardization makes it challenging to directly compare results and difficult to predict field performance from test results. This affects the entire perovskite research and development (R&D) community, independent of any specific research area, material set, or stability improvement approach."

I’m currently doing the nabcep Solar course and this information was really helpful

[@acmefixer1]

He said, "Stability is still a challenge..." IOW, the perovskites don't last very long, much less than 25 years. They won't be able to be used for rooftop or utility scale solar systems until their "stability" AKA lifetimes can be increased to 25 years. If perovskites can be made cheap enough, the sheets might be made to be quickly and easily changed when they lose efficiency.

[@yade5979]

Depends on how it gets used, i dont agree that we would need one or another, for long-living installations you could make solar cells like we have now, but for stuff where its a temporary set-up than this would be a massive success. The light weight and cheapness of the cell makes it perfect to be put on stop of cars, it would be a perfect addition to electric cars, and given that most cars are used during the day, i would say that a much much smaller battery could be out into such a car all in order to reduce weight and give a small timespan in order to go through moments of missing sunlight. This technology would be a godsend in areas where there is a lot of sunlight to begin with. On top of that, if they manage to scale it up and make it light-weight enough, they could even put it on clothes for induvidual uses, so your smartphones battery timespan wouldnt be the main concern of yours anymore, and a single piece of clothing usually isnt used for over 15 years , so the cell would be a great fit on that as well. And on many many other consumable goods this technology would be perfect, for example you want to go into the forest and relax but not miss out on the convenience of electrity, you could just bring a big piece of cloth which you span on a open field, than charge your devices via that. Maybe im a bit to positive on the good aspects of this technology, but i thing that given the trend to having more smart tools surrounding us, this technology would fit right into that market.

So put them in a place where they won't be exposed to the outside elements and be temp controlled. I know that sounds crazy, but I have an idea (and a patent) if you want to know more, let me know.

[@kly8105]

Other companies have to intentionally bother making products obsolete over time, if this is both cheap and has a decent but not long longevity its not that big of a negative either, specially since there's manual labor involved (it might help sustain the market since more installations over time means more laborers supporting it to get more labor out of it). Not a fan of planned obsolence but still worth noting I think.

[@Knightyme]

The life of these new panels vs silicon panels, assuming the 15x production saving = 1.66 years. so if the formula lasts 2 years before having to be replaced, that accounts for the cost of a worker to replace the panels, which after the initial install would be a 30-60 minute job of unscrewing one set of panels and screwing in the new set. Benefit being new formula(s) that might mean longer life and / or more power both of which are of benefit to the user. Loner life = less re-installs, more power = feeding more back to the grid for credit off the power bill.

One way to improve solar panel efficiency is to install blocking diodes between each of the solar modules within the panel. Conventional panels when just one of 60 sells is shaded will reduce output by as much as 50%. This is because the shade itself becomes a load on all the cells that are receiving sun and the energy is diverted. Blocking diode to prevent the solar cells that are in sunlight from feeding back into the Shaded solar cell.

Concentrated solar power is more efficient and easier to manufacture. Polished metal parabola pointing at a heat exchange coil in the focal point. Use the heat of the sun to drive a steam turbine. This process heats water, provides passive radiant heating, and generates electricity. Considering that heating is the biggest energy consumer. Hence why Canada has the largest geological footprint per capita. Excess heating is actually a good thing. Heat is energy after all. In fact a flame can refrigerate.

[@glenecollins]

@@brendanwood1540 concentrated solar power can be cheaper per m^2 when you have plenty of room and can implement tracking etc (there is a design where the pipes run along the centre line of the mirror so the whole thing basically just has to tilt up and down which looks pretty good for areas where you want fewer moving parts) There are a lot of places where PV is a lot easier to implement and it is potentially considerably more efficient because there are materials which can generate electricity from at least near infrared all the way into UV, there is no way you could get 50% efficiency in a solar thermal plant. (And obviously they wouldn’t work on a vehicle or a house roof or to take camping or whatever) PVs have a fairly long lifespan and they don’t require much maintenance before they are at their end of life so you can see why they are attractive for solar farms.

[@kraziecatclady]

So, I have actually read quite a few research studies related to perovskite panels. Most of them were from the Institute of Electrical and Electronics Engineers (IEEE). It seems that there are two major issues with perovskite solar panels. One of them was mentioned in the video, but not with a lot of detail. Currently, perovskite panels have an estimated lifespan of approximately 10 years. They did mention durability problems, but didn't really emphasize just how long they are expected to last. They kind of jumped around a bit on it instead. The other issue is related to this, but probably more important. Because they degrade faster, they also leech chemicals, such as lead (and the other materials they are made of) into soil and waterways which has the potential of contaminating our food supply if placed in agricultural areas, and drinking water if runoff makes it into water reservoirs. Some of the chemicals that leech out are not harmful at the low levels that make it into soil and water, but other chemicals used in the construction have not really been tested to determine if they will be safe for humans (or other creatures) at any level if they contaminate our soil or waterways. Lead is not safe at any level, so that is a major issue. The ability to manufacture them at such low temperatures is great when it comes to cost and production related environmental hazards, but it also means that they can begin to degrade at those temperatures as well. I'm sure that is what the people in the laboratory are probably working on tackling, but if something like this gets pushed out too quickly without solving this issue, it could cause a lot more problems that the ones it resolves. Hopefully, they figure something out though, because otherwise, they seem quite promising in comparison to traditional silicon solar panels.

[@Bancheis]

Yeah when I saw the extremely low temperature required to make them, I immediately worried about the place where it would be ideal to use these things. Places like Death Valley and multiple locations in Arizona. With air temperatures going over 120 degrees Fahrenheit and ground surface temperatures with the potential to go above 200 degrees Fahrenheit, I am skeptical they could survive the full 10 years projected.

[@AnalystPrime]

Good to know people who develop this understand they do not need to compete with silicon panels in how long they will last when they can provide more power cheaper and for less weight. Needing far less material and lower temperature to make them also means the energy cost of making them is far less, meaning they need even less time to recover the energy used to make them than regular PV panels. And the materials are far easier to recycle too. With such benefits these panels would be viable if they just last for a decade or so, and even that is more for people's convenience than actually needing to produce more power over its lifetime. It actually starts to seem like the demand for panels to last 25 years was put up by some people who do not want us to have cheap solar panels...

Not only does it have to work, it has to be fairly easy to manufacture, it has to be cost effective, it has to be financed and promoted correctly, it has to pass the myriad EPA regulations, and today it has to be recyclable (otherwise the disposal costs become prohibitive. A good example of how a technology can make a wrong turn, is the straight screwdriver and the Phillips screwdriver. Back in the day, they were both competing for the emerging consumer tool market, but the developer of the Phillips screwdriver wanted more money than the straight screwdriver did, and so most people chose the straight edged screwdriver. It wasn’t until much later that the Phillips got any traction.

To me, since I missed the research and development, both of these two technologies are novel ideas I missed and should be achievable from the day you came across them in 2000. I can visualize a time when a combination of of ways to capture energy are used in new and old working ways to make use of every conceivable way in the construction of homes/buildings. From windmills, solar panels, and modified building materials are used in combination and surpass the needed supply of energy in a home. The best way I know to do this is make a material list for construction and find ways to modify them to collect energy. The window/solar panels and creative ways to use a paint is ingenious.

[@timvincent5770]

Here is s an idea that just popped into my head. Have 2 kinds of special paint..layer them many many times like a battery. A layer that is positive+ charged and a negative- layer charge and in effect, turning the paint into a battery to hold or create a charge. The (+ - + - + -) layered material can collect, store, and make use of the energy.... exactly how batteries and capacitors work that way.. Why not "layered paint" or a prefab house material similar to plywood. The prefab material would be exterior coverage and even work like the current solar/shingles. Think about every construction needs and dual purpose them.

Thomas, and everyone reading this consider what else could be dual purposed. What about ASTROTURF durable enough to handle the wear and tear required? And...COULD a REAL grass be engineered to collect and store energy? This list could jgo on and on. Electric cars don't need a radiator. Why not open up some air scoops or utilize the empty part where a radiator would be and put fan generators in every conceivable spot? Turbines. ducted fans... How about using a rocket or jet engines as a template and take the passing air and reduce the throat to create MORE pressure to collect energy while adding to additional thrust? Maybe use a very heavy element such as lead to make a heavy magneto/gyro, that once spinning will want to stay spinning especially in a vacuum and could store more kinetic/potential energy than any kind of battery.

It's really great to see new options, and perhaps Perovskites are the way to bring thin film and BIPV back to the forefront, if the logevity problems can be solved, but even if they can, industry is slow to adopt technologies that don't have a long history already, so I wouldn't be surprised if we had to wait another decade for Perovskites to make any significant market impact.

Great information and explaination overall, thanks for the vid. But it was a shame to not talk about a very important counterpoint against all multi-junction solar cells, the recyclability (poor LCA). It's all well and good if they're cheaper and easier to make, but if they are harder to reuse the materials, to make the cost of 2nd life materials as cheap or cheaper than mined raw materials. You will have problems for energy from the 'renewable' panels to truly be renewable. With finite resources, you must be reaching towards material steady-state.

[@josephcoon5809]

That’s why the panel should be passively optical. Being only polymers and silicates, manufacturing would far cheaper; both from material costs and manufacturing complexity. Then you use passive optics to transmit the optical energy to a centralized conversion system. You can passively disperse the light by wavelengths allowing you to direct particular wavelengths to its respective material which do not have to be layered with other materials to accommodate different band gaps. Furthermore, passive optics are impervious to EMPs like from lightning, solar flares, or upper atmosphere nuclear explosions. The exposed portion of the system is cheaper to manufacture, replace, recycle, and disperse. The more complex conversion systems are safe in the basement. A side benefit is directing IR wavelengths directly to pavement panels allowing you to melt frozen precipitation without converting light to electricity to chemical back electricity to power metallic heating elements. Oh yeah…didn’t even mention the aspect of harnessing IR for thermal applications such as water heating, water purification, radiator heating, and steam turbines for more electrical production.

Until many people had succumbed to lead poisoning, we were not aware of the health issues, and lead worked cheaply and well. After learning about the issues, we switched to other materials, some of these alternatives were already used somewhat. But lead was still being used in paints until like the 80's....partially because alternative materials cost more.

When you see statements like X country produces x% of its energy demands from wind/solar, but the optimal maximum producing capacity of those installations is so far off from the real world if you take into consideration the efficiency degradation as time passes, the production of the energy when is not actually needed (this means that is just theoretical, because at night we don't use electricity from solar for example), etc. People take those numbers as real numbers...

How about integrating photovoltaic with radiative cooling panels? It will keep the panels cooled sending heat to outer space through emitting specific infrared frequency that escapes atmosphere. It will help with durability issue dramatically!

[@Shoi5]

It's a good thought but fluid based systems have issues of their own. Fluid tends to be hard on materials, and active solutions with pumps and valves will wear out. If you design something to be cooled, what happens when that cooling fails? What fluid will you be using in the loop and will it be bad for the environment if it leaks? How much of your power being produced is dedicated to the cooling solution? Many solar plants already have high work hour demands with just cleaning the panels, and that is low income work. Plumbers and fluid engineers are much more expensive. In household solutions it can make sense (the products do exist), heating your hot water tank and providing power with the same device but the issues are still the same. India has been using a middling strategy, they are installing solar over canal systems and water reservoirs. Evaporation from the water lowers the temperature of the panels and the shade the panel provides limits the water lost to solar heating and evaporation. It is a passive solution that still lowers the expected lifespan due to moisture levels and corrosion, but the cooling makes the panels much more efficient while they work, to the point that the tradeoff is worthwhile. This solution also improves cleaning effectiveness, water is very close so you don't need as strong of a pump, and the water drains back into the source rather than the ground. Nothing is perfect but smart people over time eventually get to simple and genius solutions, who knows what people will come up with!

Yes, I was firstly concerned by the mention of the use of 'lead' in production. Lead, of all things. And from there I thought of the problems regarding recycling. If it's going to be such a cheap product to buy, unless recycling is just as economical (and safe!) - expired panels may well end up being stuck in landfill, buried or shipped off in bulk to poorer ones rather than being properly recycled. Should these panels become a reality - and they are made using lead, I think it would be better to 'price in' expected end-of-life recycling costs from the 'start,' and government checks made to ensure manufacturers genuinely recycle old units responsibly and not dump them elsewhere. And that, of course, highlights the problem of 'where' they will be made. In the West, manufacturers have to bow to tough environmental laws - and yet they still cut corners, despite the risks of being caught! Manufacturers in 'certain' other countries that 'specialise' in cheap massed manufacturing don't give a monkey's for environmental laws - so firstly, it will be difficult to make them take expired units back; and secondly, practically impossible to know how they deal with units once they've received them. So, Western solar units will have to be made and recycled in the West to ensure they are safely dealt with...somehow, I don't see that happening. Profit is always king in such situations. The more I think about this, the more worried I am about it to be honest.

Perovskite's advanyage of crystalizing at much lower temperature (say below 100) is an advantage as well as a drawback. The low temperature enables the cell to be manufactured easier and cheaper on transparent materials, but also potentially degrades its lifespan and problem to operate under high temperatures (eg: 80 degrees or higher). The trick is to find a material so that before it crystalizes it requires low temperature, but after it crystalizes, it'll need significantly higher temperature to disrupt the crystals to achieve much better stability.

If it’s actually much cheaper, then the low cost could supplement the “short” lifespan. Also, the higher efficiency would make it beneficial to have a replacement schedule. But, each time we hear about cheaper tech, it is always more costly than what it replaces. Eg, carbon fibre parts, aluminium parts, cars made with more plastic and paper and thinner/less metal, all costs more than the predecessor. 😏

[@sweetshiba_]

Hi! I do research with perovskite optoelectronic materials, and the issue around perovskite lifespan is less about the cost, and more about the environmental effects of perovskite film decay. Most perovskite research is based on a structure that fundamentally relies on lead as a constituent. So, the worry is that if the material decays, harmful lead salts could be introduced into neighborhoods and ecosystems. Also, the stability issue as I understand it is more detrimental than described here; leaving an unprotected lead halide perovskite material in any hot, humid, or even heavy rainfall environment would cause the material to stop performing & decay into lead salts, which, until addressed, seriously limits applications. Even exposure to air in lab on humid summer days can "kill" the materials useful properties. I hope this helped you understand the perovskite's stability issues more!

If you want to convert 20 wavelengths, buy the respective filters for those particular wavelengths.
