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.

[@johnpeters6147]

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.

[@sphong0610]

@@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.

Very well written piece. Twice, so far, he mentioned something I was questioning. This one was when he said the two chips were samples used in the lab. I was thinking when he first talked about them, they seem a lot closer than 10 years away.

[@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.

[@jkcleanenergyman6573]

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.

"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."

This was a good video and I'm especially happy you went into the challenges it faces although I always end up frustrated not really understanding how they go about improving the poor aspects. Like, what specifically allows for one of these substances to be more durable to heat and how do they go about trying find it? I also find it sort of alarming that this crystalline structure was just found in nature rather than come up with. Is it possible theres an even better structure and wouldn't trying to optimize that be the most important step. I mean, it's possible that all this research into perovskite's becomes useless if some better structure is found so shouldn't we first develop the science around finding the best structure?

[@donatoge1713]

so i would advise some Real science courses... learn some chemistry and physics....but typically its about finding a material, or creating one that suits the need better. Only quite rarely is there truly only one substance that will work for a given need, but how well it works, or its cost, or potential environmental concerns.... ect., determine what substances are actually used. We used to use lead as a fixative in paints, in pipes carrying water and many other items. 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. Lead based paints no longer dominate the market because better paint types were developed, and at reasonable costs, else we likely still would have lead paint in our homes schools and hospitals.

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.

[@alokverma3311]

yeah ..nice explantation ....but now a days the solar cells on the modules is devided in to two parts so that if shadow came then this not effect the entire efficiency of module. this technique is genrally use for module powers are arround 400 watt or more than this.

@@alokverma3311 Good to know. I'm experiencing this issue with 240W panels. 60 cells. Cover 1/2 of one of the cells and power drops from 180W to 80W. It's really shocking how little obscuration can cut way down the output.

These videos about “new developments” are always interesting, but I’ve learned to take them with a big grain of salt. I used to subscribe to Popular Science back in the 1970s, 80s and 90s and they’d always be showcasing some new technology, only to have it completely disappear after that. There are SO MANY things that can derail a technology. 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.

Exactly, we public are easily enamored of the 'discoveries' that have yet to be producible due to cost, restrictions, etc., only t discover that the corporates are continuing dangerous and toxic energy productions.

[@glenecollins]

Back when I was looking at them in uni the big problems with perovskites was the inorganic part is usually a heavy metal cation and the film is usually is pretty water soluble. So manufacturing and end of life recycling is a big deal for them unlike with silicon solar cells.

[@brendanwood1540]

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. Here in Australia a lot of solar farms have been able to pay for themselves in

Actually , the main reason they want to make it transparent is for heat absorption to be low. Current solar panel has a black surface which actually absorb heats towards earth which is bad as we do not want it to hear our planet, instead we want it to reflect it back outside of our planet. That is why they do not consider it to be black. I hope this helps.

[@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...

Yeah Perovskites return their initial investment in as little as 6 months by estimates(even lower by some, but that's optimistic) so a solar cell that last only 5-10 years should still be competitive against fossil fuel or mono-silicon PV.

When I was working on machines to laser scribe thin film solar panels in the early naughties, all people were talking about was getting the cost down to $1/watt, we hoped thin film was the way we would achieve that, but economics of scale have meant that monocrystalline cells dropped in price far more rapidly than anyone imagined, pricing out cheaper, but lower efficiency, thin film technologies, even Cadmium Telluride (which was horrid to work with, ask and I'll tell you about the extraction system we built). 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.
