As I understand it, it is about adding the Perovskite as a layer to absorb more frequencies that somehow are passed on to the underlying normal silicon which absorbs less frequencies on its own. But then, what about the 1 micrometer film? I guess, the film is part of the sandwich that makes up the pv. How do they adhere the film to the silicon substrate? Furthermore, Perovskite here, seems to refer to the structure which is so typical for Perovskite more than to the actual atomic elements in the (perovskitian {?adjective?} structure. Unfortunately, no 1 micometer solar panel then?

the supercool thing is, that the additional efficiency is still there in winter where the loss of energy mostly affects the infrared part of the spectrum. using them vertically on a fence or balcony still gives you a good amount of efficiency in winter. the vertical installation is not perfect in summer but it is a better balance throughout the whole year for people who live a few thousand kilometer away from the equator. and together with a sodium ion battery, you get a quite affordable setup to produce cheap energy everywhere all year. btw.: the University of Bayreuth pushed sodium ion batteries to 165Wh/kg which is fantastic!!! the future of renewables is bright!!!

There is another approach to further improve efficiency: With current silicon is it is cheaper to buy extra panels than to use solar tracking. But, as the kWh per panel increases with perovskite layering, presumably cost/kWh will drop while cost/panel will rise. That sets the stage for tracking technology to become economically viable in general. (It is viable in the small set of edge cases where you need a certain amount of power, but have a limited space for panels.)

I think efficiency is a bit of a non-issue assuming panels became still an order of magnitude cheaper. 10% efficiency is totally fine if the panels or film sheets cost tens of dollars. Most places are not efficiency limited in any way. What's more important in many higher latitudes is having enough extra panels to be able to make dual-sided west-east farms or have separate panel groups heading east, south and west and be completely ok with some of the panels producing next to nothing for 2/3 of the day time. Winter production also practically needs vertical panels which are not that great during the summer. If they're cheap enough so you can build a summer set and a winter set it won't matter much. Panels need to be so cheap that we can extend the morning and evening curves as far as possible. The mid-day production peak will soon be an actual problem because there is nowhere to dump the negatively priced electricity.

I was mucking around with the idea of using my solar system to replace gasoline rather than grid electricity the other day and found that powering a car ( EV) saved me 4 times more money in gas than using to replace grid electricity. I then went a little further and thought what if I cover the entire 150 sq metre roof of my 4 bedroom home with panels and came up with this. It would cost $40k (Australian) and generate enough to power 14 EVs each travelling 400 klms each week for 20 years. The weekly solar cost of each EV would be $3.00. The cost was mind blowing enough but what really astounded me was that just one residential roof top could power 14 cars.

I hope we have another order of magnitude of price reductions on the silicon, but it's pretty far along the S curve now. Of course another halving of solar electricity is great if combined with perovskite or other multi layer technology, but 10x reduction...already costs to install on roofs is becoming the biggest issue.

Things will likely go the opposite way. It is expected from perovskite solar panels to be extremely cheap, as they basically can be a film, instead of silicon+glass construction. So after the initial higher prices (where customers with limited roof area will want to pay more for the new tech with higher efficiency), the cost of silicon+perovskite sandwich should become similar to silicon-only designs as solar panel manufacturing transitions to it. And there may also be competition from extremely cheap (at a cost of much lower efficiency and product life) perovskite-only adhesive solar film products or similar.

Thank you for this video! This is one of the subjects you've previously covered where a follow-up is probably most valuable, because perovskites have such enormous potential.

Cubic PV is a few years behind them with lots of innovative new ideas and plenty of funding, but no factory built just yet. And behind them are researchers in different countries with their own innovations, but so far none have gotten outside of the lab. Well, here's hoping Oxford PV is a big success! Hopefully they'll pioneer this new technology, maybe with Cubic PV as their biggest competitor, making it both commercially successful and increasingly efficient.

For example, the system operator could electronically call-out for release of electric vehicle battery energy into the grid when there is a risk of network instability. I think that forward-looking people in society would be happy to help stabilise the electric grid and get a discount on their electric bill at the same time.

It starts making sense to shoehorn in solar anywhere and everywhere, including areas that don't get great sun exposure or have perfect exposure angles or where weight is an issue or it's barely worth it with today's solar panels, eg tops of cars (so many people think this is an obvious idea, but for the added cost and complexity it barely adds a few miles of range per day - the equivalent of plugging in for a minute or two... assuming you've left your car in full sun all day. But if it's cheaper than paint, then it certainly makes sense!).

What excites me most about perovskite tech is the potential for automotive/transit. Currently Aptera is the only car company that can make solar charging worth it because of their insistence on extreme efficiency.

Funnily enough, at the micro-scale is where something like this would really help. Electronics with ultra-light super efficient solar panels would enable distributed sensors in a way not currently possible. This could help farmers target irrigation to drier parts of their fields, alert logistics companies to the location of equipment like trailers and dollies, amongst other things.

What are they used to catalyse?

I'm a long time fan of perovskite and it's so pleasing to learn they've managed to reach sufficient longevity. Looking forward to the first perovskite car paint 😀

This was a very informative video. Thank you!

I am from Pakistan. Your videos are really interesting and I love to watch your videos.

Well done, it looks like we are all looking at a good 40% additional increase in efficiency.

Great video as usual.

Dear friend, thanks for an excellent and comprehensive presentation. Today I learned. Oh, and greetings from New Mexico🙂

thanks for this information...

Hi Dave, You may already be aware, but have you heard about fluorescing light guides? 🤔 Robert-Murray Smith talks about them and gives some demonstration here on KZread. The efficiency increase from this simple modification is astounding. It's more approachable for the everyday citizen of Earth, as well. Though I could imagine an even greater increase in energy capture once coupled with perovskite technology. 🧐 Great video 👍 Thanks for keeping us updated and in-the-know. I appreciate what you do for us here on the interwebs ✌️✨

One of the few great sources of information whose voice I can stand listening to. Love you don’t shy away from being real

I am encouraged to learn of multiple ventures employing people who are working so hard to bring us solutions to our energy issues and the challenges of getting past burning things to make our civilization possible. If we can somehow survive the next 30 years, then the solutions will be only 30 years away. 😁 Perhaps our grandchildren will experience these breakthroughs. Thanks again, Dave!

Thanks

Nice job

There’s some new Dutch research that suggests the angle of solar panels is all wrong, would be good to hear your interpretation of that. Keep up the good work 👍

Thanks Dave. Let's wait to see who is in full-scale production of these 30%+ efficiency panels.

Another excellent presentation, thanks. 😁👌👌👌❤️❤️

Just like money at compound interest, incremental improvement over the long haul amounts to significant gain!

Great video as usual. The increase in efficiency from 22% to 33% sounds great but I haven't seen anyone mention the fact that is a whopping great 50% increase in power output. My 5kWp array in Spain produces around 35 kWh per day in the summer months (more than my needs) but only around 12 to 15 kWh in the winter. That 50% increase in the winter would be a real bonus.

This is very exciting, I hope the durability of these products is for real, and the pricing is competitive too.

Danke!

TY! ❤

Great video! In terms of ways to improve a solar panel, how about using all that extra energy they capture in the form of heat for something useful like heating house. Right now that triples the price of a panel. Ought to be able to improve on that.

Great and informative video. Well done.

Random comment for channel interaction.

Just remember to multiply the time to market estimates by the appropriate reality factor. These values are: 3 for scientists 5 for management 10 for marketing

One of the reasons for concern about the ultimate efficiency of panels is available space. Whether domestic, industrial or scientific, a limit of space puts a ceiling on the generating capacity. If Perovskite cannot offer a significant increase in power output AND durability on a par with silicon those of us with space should press on with installations rather than wait for a peak efficiency which may never come at an affordable price point. Even so, if the cost of a more productive panel is proportionately high, silicon may still be the viable option. The environment needs action right now, not when science delivers next gen tech. Government has failed. Unless everyone of us takes what independent action we can we fry. Simple.

Uhhh? Pk should allow up to 50% - today cells are more closer to 20% -> allowing up to 30% with PK today. Another layer is also in the works that just converts IR to visual light as well. Main problem isnt the cell - its the storage more than making the power. Lots of power is wasted today because we dont have away to store it.

Saule Technologies, Poland, is another. They develop inkjet-printed, ultra-thin, and flexible solar cells based on perovskites.

@@user-xy3lm6pw8j To be fair Saule are still very small but all good luck to them, their developments look highly promising. I am interested in supercapacitors and the potential for PV energy harvesting for IOT devices.

I hope they transform my house, as well as the market. Now for the real roadblock for home solar.. the battery! These updates are very good. To know that some of the claims actually will come true in the near future.

Excellent video 🎉😊

Yep this is the year I'm finally going solar. It's cheap enough that it would be dumb not to.
