Congratulations. Maybe you can answer my query: When Perovskites were first talked about, there was a lot of excitement about them being ultra-thin layer, flexible and could almost be painted on a surface. I'd prefer a dirt cheap, throw 'em anywhere, 15% material, one so cheap you would stick it on N-S-E-W facing roofs and walls and yards. When can I have those please?

The trouble is these days most folks are not mathamatically or scientifically literate enough to even remain sceptical regarding claims, let alone decifering what is important and what isnt.

Perovskite PV cells in development today contain lead which I'm glad was mentioned in the video. However they didn't mention that the lead leaches out of the panels which is really not great. A lot of work is being put into encapsulating the panels to stop the lead getting out, but even if successful it's going to be a problem at end-of-life processing. They also tend to degrade quickly, which is also not great; they have great efficiency when new but that tanks within a few years (as in, service life less than 5 years). No mention if this group has managed to address that. We'll have to wait and see how the economics work, since they didn't discuss costs. Sure, if the levelized cost is lower that's a win, but I'm not going to be celebrating anything until the data is available.

It's not addressed in the video how, or if, they addressed that problem.

[@Smidge204]

@@evilutionltd It was a trick question, since existing PV panels contain lead and "Fixed-location photovoltaic panel installations" are already blanket exempt from RoHS restrictions. This is how I knew you were talking nonsense; it is not (currently? maybe in the future) necessary to comply with RoHS limits for PV panels used in non-mobile applications, therefore they are already compliant with the law *despite* the known problem of lead leaching out of them. The idea that they must have solved the problem because it would be illegal to sell them otherwise means you don't understand the law (and are hopelessly naive to think no company would ever risk doing anything illegal) As for intellectual property, I never asked for detail; They acknowledge that the product contains lead. If they solved the leaching problem, all they'd have to do is acknowledge that too. Anyone interested in this product will be able to read the Wikipedia page (or god forbid any of the many scientific and industry papers on it) and immediately notice that there is a lead contamination risk, and anyone considering investing in the company or buying their products should then ask how, or if, they manage that risk.

I work for the world's largest silicon solar module manufacturer and am excited to see multi-junction cells come to market, soon. I can honestly say, without getting in trouble, that virtually all large module manufacturers are in late development of multijunction cells. Curious what the lifespan of perovskite is now, as that has been the limiting factor.

[@spankeyfish]

I wonder how many different absorbers can be layered atop each other

[@jukeseyable]

its still terrible, they are just not talking about it, they are just 1/12 th the lifespan of mono crystaline pannels, so despite been more efficient, perovskite become less efficient than mono crystaline after just 12 months, then they degreade rapdly with a lifespan of around 2.5 rs, compared to 25 to 30 yrs for mono crystaline. but this isnt mentioned anywhere in the video,

If you want efficiency, solar Stirling can be 30% for a well maintained unit. Been that way since the 80s.... But I think you need a concentrator that tracks the sun, so it's not set it and forget it. Maintenance is kinda high....

That was a great explanation. I didn't understand the potential of perovskite until now. Mind blown 🤯

[@mycosys]

The potential to poison generations with lead?

[@jukeseyable]

and you still dont because they didnt mention how quickly these pannels degrade, they last just 2.5 to 3 yrs. this is the problem with perovskite, all though they are marginally more efficient than mono crystaline when new, after just 1 yr they are less efficient than mono, and then degrade rapidly to the pint of failure after just 3 yrs. As things stand, at best they are an immature technology. at worst they are a dead end. also solar pannel efficency is a total moot point, its just single figure % gains. so a standard 400 w pannel at most becomes a 420 watt pannel, far better just add an extra pannel, and this is very achievable now as pannels have become so cheap

Yes, as others have said, we’ll guess she wasn’t allowed to include longevity as a direct question and receive a direct answer. Surely that’s the key breakthrough.

If it has been mentioned previously, please forgive me. If we can convert more of the suns energy to electricity, this could reduce the heat component, of solar panel operation. This should reduce production degradation as the new panels converts more radiation to electricity rather than heat. Very much looking forward to our ability to capture a wider range of emissions for conversion to electricity 😀

[@diwe9984]

I'm looking at this and wondering why the German government has modified the Renewable Energy Sources Act (EEG) - valid from the third quarter of 2024 - in such a way that it becomes as uneconomical as possible for newly constructed solar systems by private individuals for private use in their own homes. Were the "big customers" - also known as energy companies - very helpful in writing the new law?!

[@corradoalamanni179]

They removed export remunaration ? Or something else?

[@LastWish90]

Probably lobbying from the energy providers and the fact that we have too much renewable energy in the grid already on some days, especially if solar kicks hard around noon and many PV arrays still facing south to creat the maximum amount of energy during the day to get the most money out of it, at some 20 years ago people we getting 0.40-0.55€/kWh produced and exported to the grid and they get these rates for 20 years, now imagine a 10 kWp array in the early 2000s that would be a little under 100.000€ for you in these 20 years, basically offsetting the cost of the whole system and after that you probably have another 10-20 years of lifetime in the cells left.

[@aussie405]

This sounds great.

[@Leo99929]

It wasn't covered in the video: did they solve the stability and durability problems with perovskites? Last I heard they degrade in direct sunlight, or with temperature and humidity changes you naturally experience when in use. It's all well and good if they have higher efficiency to cost ratio out of the box, but the thing that matters is the average cost per kWh over their warrantied life span. If their increased efficiency drops off within the days, weeks, and months that perovskites historically have then I expect the cost might not work out cheaper over it's life per kWh delivered. So, what is that, and how does it compare to silicon?

[@mycosys]

And when they do, they release lead into the environment

[@colinwiseman]

I don't think they will answer. I wish there was a service out there that could search all interconnected documents like an engine. That could be useful.

[@Leo99929]

​@@colinwiseman I was being polite. It looks better if they provide the answer and self correct. The long term stability issues persist. Feel free to link me to a source saying they last roughly as long as the more standard silicon if I'm wrong? It's a glaring omission from the Oxford PV guy, but I don't blame Everything Electric because this is specific scientific research and I know that's a specialist skill they likely couldn't justify the expense of within the team. The Oxford PV guy likely needs to drum up some funding for their research or potentially people lose their jobs, so it's all aboard the hype train. They likely thought that talking to Oxford PV was expert enough. The problem is that you can't trust the person who stands to benefit from it's success to give an unbiased overview of the technology. This is the problem with channels like "Undecided with Matt Ferrell" and "Two Bit da Vinci". They don't know enough science to be able to tell what is marketing hype and what is reality reliably. You might as well just read the company press release and blindly trust it. Sadly, occasionally, the fully charged group brushes close to this kind of whoopsie; hyping tech with an undisclosed Achilles heel. I suppose you can't cover such a breadth of topics without the odd thing slipping through the net. I think fully charged does far better than the other two channels I mentioned.

[@GruffSillyGoat]

A C&EN article from back in 2018 mentioned OxfordPV had developed a stable forumulation and cell layering technique that improved stability in the 1,000s of hours mark. The article mentions that entry point for commercialisation is 10,000 hours mark, with high recyclability, as the OxfordPV panels are focused on commercial use then they may be targetting cases where increased generation over a five to ten year lifespan is beneficial. Particularly with high recyclable panels, this may not suit home generation where long durable panels (15+ years) are more cost effective.

I think its worthwhile to transparently talk about the downsides of tandem. Scalability, cost and reliability comparison with standard silicon solar cells side by side should be discussed. I know more 100M of dollars have been invested into OxfordPV over a decade, and yet Commercial product is still no go... since spot price of PV is so low now below 10cents per W..., i think tandem should be used on specific application that silicon cant be used. I think they shoukd consider more specific application. Perovskite is cheap but rest of the layers that are used to make the device are insanely expensive...... like over 4000usd per gram.. I value breakthrough in science, but climate change is coming too fast.. time to cut some corners to focus on what works or not.

[@nickwinn7812]

Exactly. We already have all of the tech we need to get to carbon neutral quickly. If we focus on doing that now, we can develop better materials and systems at our leisure after we have achieved that goal.

Such efficiency of solar panels would allow the production of electric cars with solar charging and even allow light low-speed electric cars to drive directly from the sun.

[@nickwinn7812]

The problem up to now with pervoskite has been durability. No discussion of this issue in this presentation. What is the expected lifespan of these solar cells? A more efficient solar panel, with a significantly shorter life is not a good trade off. Silicon's durability is phenomenal and solar panels fitted now will be in service for decades ahead. That is true sustainability. Efficiency is only an issue where space is limited, and frankly, if we used all of the roof space currently available for silicon panels, regardless of orientation, we would hardly need any solar farms on other land.

[@jukeseyable]

not sure where you have read 15 years, as most scientific reports state lifetime in hours, the best figures I have seen that are in propper scientific papers and not press releases, are 3000 hrs for silicon doped perovskite, so less efficient, but more durable . that in the uk would give you around 3 yrs use, so a long way to go. the 15 yrs could be untill total failure, the 3 yr figure 3000 hr is time above 90% of initial capacity

I think time for economical competitive is not here yet. Also this time we heard nothing about how long life they will have. Will they ever reach 40 years lifetime as silicon cell already have?

[@GruffSillyGoat]

In commercial applications, where the higher efficiency makes a tandem panel more cost effective, long term durability is not necessarily the goal. Even silicon only panels will be swapped out before their maximum lifespan is reached as their efficiency will have dropped and replacements/newer technology panels would be more cost effective than keeping the older ones

In short no, OxfordPV own the most patents for this technology. They may intend to seek a licensing approach rather than manufacturing one (just like ARM does in processor chips). The German plant is relatively small scale in partnership with a German industrial partner with expertise in this space. The panels produced sound like they are destined for assessment at commercial generator partners round the world for assessing in their existing farms under varying real world conditions. If the trials and OxfordPV choose the licensing root this will likely generate more revenue for them, and UK tax take, than manufacturing alone. Plus will accelerate the adoption of tandem panels and so the output from renewables globally.

The perovskites don't have 20 year nominal life like silicon . More like five years. The heavy metals used are a concern. I had cadmium telluride panels and my house burnt. Where did that toxic cadmium and Telluride go?

[@milan_dobias]

Excelent episode! Happy to see Imogen back with a nice tan and looking forward to next videos. Information I got so far from other sources only referred to perovskite cells in developement, this is first real aplication which is much more relevant and exciting! Kudos also to the person behind cutting these videos, a job very well done!

[@grahamcook9289]

The world needs as much PV as it can deploy, along with renewable energy STORAGE!

[@RayleneCawood]

"World record" for how long? How long before the perovskite cell's lifespan has ended or is so bad that it's worse than the old-school cells..? Does the vid address this? Dare I watch it?

[@LiamRedmill]

Sorry,but the Chinese have made advance's with these material's 2,and I don't see a problem with them winning for the green rev

[@PCRoss2469]

EQ on the audio isn't great. Good Video though. thanks

[@garrygballard8914]

I have been following Perovskite development for five years now and glad to see its present development. I am getting ready to start purchasing them in my business development in large numbers. Let me know when I can buy stock.

[@jukeseyable]

dont Garry you will regret it, they degrade very rapidly, they have a lifetime of 2 to 3 yrs max. for a percentage increase in efficency that degrade much faster than mono crystaline pannels. within 1 yr they fall behind standard pannels, and after 3 they are useless. dont take my word for it research, and 2 dont do it unless you want to ruin your finances

[@LiamRedmill]

Maybe you could cover the super extraordinarily cheaply made solar "foil" cell's/film's by English crisp bag producer.this film solar invention is year's old now,but no reporting of buyable products on the market or advance's in reporting worldwide since,as far as I am aware.these could be stuck on building's(without structural support),bus's,car's,Evan bycles and scooter's ,but have vanished in the world,thanks

[@agnelomascarenhas8990]

Efficiency is one aspect. How much energy it produces over it's lifetime vs energy spent on manufacturing and *recycling back to raw materials* You could have a low efficiency material but dirt cheap and recyclable then it is an absolute bargain. Plants are like that.

[@neildolan7177]

When will we decarbonise the manufacture of renewable energy products. Never seen any videos showing any developments. If we need to do it, why not now. Its becoming clearer that we have reached the tipping point. We cannot afford to increase emissions to get to a decrease.

[@TerryHickey-xt4mf]

like using natural gas and coal etc.

[@neildolan7177]

@TerryHickey-xt4mf They caused the problem in the first place & now we are continuing with more of the same. The rate of renewable adoption is causing CO2 emissions to rise because EVs, batteries & solar are more carbon intensive. Its all about greed & profites & nothing to do with climate change.

[@scallywagII]

Most of the world's PV panels are made in China. They have deployed vast amounts of renewables. Even in the UK, a solar installation should have an energy payback of around 2 years, and less in lower latitudes. The next 30 years are essentially carbon free.

[@JunitafluxcyfatriciaJunita]

Now 550 Watt solar panels are only $90. Thanks China 🎉

[@billyray323]

Why is the production in Germany ? When are you going to produce them in the UK? Or do you already? Did i miss that! lets get British people working & build a stronger economy for all please! I'd buy some for my home, along with a battery storage system, to charge my cheap EV leaf 2nd gen. Great to hear we're making some good progress I've just looked for your production in the UK & cannot find any, so why is that? If you manufactured them in UK, British people would buy them & there would be reduced transportation costs, so lower prices & better profit, surely that's a positive for all & the environment!

[@mycosys]

His arguments for perovskite are virtually exactly the arguments for tetraethyl lead. Lets not make that mistake again, yes, lead is cheap and readily available - its also neurotoxic, especially to kids.

[@RichardFraser-y9t]

These solar cells don't put lead into the breathable or drinkable environment. There are designs of panels that encapsulate the panel and absorb any leached lead. It's not like these are given to kids to lick.

[@tonycollyweston6182]

So is perovskite as deadly as tetraethyl lead?

[@spankeyfish]

Perovskites don't have to contain lead, it is the crystal structure that the term describes. Lead's just the original perovskite and presumably the easiest to make.

[@mycosys]

@@spankeyfish OK but the story is explicit these do

[@mycosys]

@@tonycollyweston6182 OFC not, & the lead is released when it ages. But we dont need another toxic burden making us dumb and violent

[@trevorberridge6079]

The efficiency levels of Perovskite are based on the amount of solar energy that penetrates the Earth's atmosphere. So naturally the use of Perovskite in solar panels on orbitting satellites would produce more power as the solar energy will not be diluted to the same degree. This could be the beginning of solar power plants in space.

[@itsyo42]

Only if the commercial panels are graded to absorb that density of energy.

[@TerryHickey-xt4mf]

hopefully that requirement will not be needed in the future.

[@jukeseyable]

and how do you get the generated power from low earth orbit to where its consumed on the earths surface????

[@trevorberridge6079]

@jukeseyable That's already being worked on.
