Күн бұрынDownload Opera for free using opr.as/04-Opera-Browser-Undec... Thanks Opera for sponsoring this video! 2024 Perovskite Breakthroughs are the Future of Solar. Perovskites are often hailed as the next big thing for solar panels. They’re more efficient than silicon PVs could ever be, and they have higher yields. However, their fragility and short lifespans have relegated them to the lab...so far.
But 2024 is looking to be the year of the perovskite. The last few months have seen new perovskite researchers all over the world smashing records, including durability. Because of this, some of these new perovskites are even set to hit the market this year. Let’s check out some of the most exciting breakthroughs in the field and see for ourselves if perovskites are finally ready for their big debut. And why should you care?

Reasons that I hope you’ll do an episode on fabric ductwork. 1. It’s been shown to save up to 40% of the energy cost on ventilation systems in HVAC 2. It’s LEED certified because the transport cost is a fraction of the transport cost of sheet metal ductwork 3. It’s safer, there was a sheet metal duct collapse last year in Colorado that hospitalized 6 people 4. It eliminates the need for HVLS fans, reducing energy consumption in buildings I think they are the future and I hope you do a video on them eventually

I think people underestimate how much better Perovskite cells can actually be. they are sensitive to the visible spectrum with a small dip to ultraviolet, while normal cells are mostly infrared. but here is the thing, because of rayleigh scattering, how much light scatters is inversely proportional to its wavelength, meaning the light that perovskites are more sensitive to get scattered more by the atmosphere... and that is not a bad thing, that is a feature, because now you have a solar panel that is not just sensitive to the direct infrared light, but also the scattered visible light, meaning it still generates energy when not in direct sunlight, it will also respond well to scattered and reflected light. meaning peroviskites are much better for example for vertical bifacial solar panels.

Sounds like copium. Absolutely none of that matters - beyond niche applications - if the value proposal for perovskites doesn't make sense. I'd be hesitant to invest in yet another corporate solar boondoggle with probably anyone other than a company like Tesla because the devil is in the details. If you can't make them cheap enough to be competitive at scale for what...an extra 5% efficiency...then it looks like just another venture capital stock pump scenario. Also, as a general rule, if Bill Gates is for it then the consumer interest definitely isn't the priority, as demonstrated over and over again with the type of things he backs.
@debashritmishra5019 19 күн бұрын
You're right that perovskites' visible light sensitivity and Rayleigh scattering are interesting! While scattered light can be captured, it's generally less intense than direct sunlight. I'm curious to see more research on how much this actually contributes to overall energy generation compared to direct sunlight capture. Perovskites are definitely a promising technology though!
@danilooliveira6580 19 күн бұрын
@@MrCiaranm it's smaller of course, but it's free gain. even if it's not the maximum possible energy they can capture at any given moment, it's more than a normal panel would at the same conditions. so if, for example, horizontal panels are not as logistically viable for your specific situation, you could use vertical bifacial perovskite instead and lose a lot less than you would with vertial panels. but even for normal horizontal panels, we are now talking about panels that will not only generate more energy, but will also have a less steep loss of efficiency curve as the sun goes down. it's a huge improvement over normal panels that the simple "more 4% of efficiency" don't make justice.

A view from Scotland where we fitted solar & batteries last year. The technologies are going to keep moving, at some point you just have to go for it. There are good offerings now that are established so you don't have to be 'bleeding edge'. If you can, find a recommended local fitter. Consider if you can get everything in one system that has one interface to talk to it all. For example, our fitter included a heater for hot water so the system could do that in preference to export. Wasn't in our original plan. It has been really successful but, as it's a different make to the other kit, we can't control the different priorities as much as we want. This is a minor quibble though. Best of luck.

You wouldn't like that very much, would you? So why should I like government forcing me what I can buy? The reality is that we'll need a mix of energy sources, even fossil fuels in spite of what the religion of green energy says. There's no such thing as green energy. Any energy extraction from the environment has negative consequences. We should be striving for less overall energy use not more efficiency. More efficiency just encourages people to use more energy. This is a well known but not well publicized effect

If anyone is curious, a big reason for the instability issue is that MethylAmmoniumLeadIodide (the main perovskite solar compound, although I'm sure newer advancements have all sorts of fun dopants or substitutions in there) is fundamentally a metastable state. This leads to some of the great charge transport phenomena, as perovskites are remarkably resilient to grain boundaries. However, being metastable means that injections of energy from things like heat, sunlight etc... can cause the PbI to leave into a more stable, less useful phase. Hopefully some of these researchers can solve this, but it is a truly tough nut to crack as the thing that makes the perovskites so efficient is also the heart of the problem.

Sure it would 😂 that was not a superconductor. The problem is that perovskites (currently a bit more stable formamidinium instead of methylamonium is used, often alloyed with Cs) are inherently unstable under illumination and bias due to electrochemical oxidation of lattice iodide, which then triggers chain reactions leading to ultimately decomposition to various volatiles and PbI2.

Just to clarify: by _year of perovskite_ the marketing managers mean _the year to invest in our company's version of perovskite._ In most cases this is over optimistic hype for potential investors. After perovskite technology is refined to the point where it is ready for wide scale deployment, it will take years to scale up the manufacturing to the point where it will see wide scale deployment. (If that ever happens.) I got some early flexible perovskite solar "panels" from a company that was going out of business. They only have single digit efficiency, but the intent was to make the cost per installed watt lower than silicon panels. In theory these could be glued to metal roofing. It was a plausible business plan when proposed, but they assumed that the cost per watt for silicon panels would drop at 15% per year. It actually was dropping at 50% per year. In the years it took to get their factory running at preproduction volumes, their business case fell apart.

Slight correction: Whether it is p-i-n or n-i-p is decided by whether the p or n layer is deposited first (not the sunny side). The perovskite changes behavior depending on what material (p or n) it has been deposited on then. P-i-n (or inverted) cells are more stable probably because of less chemical reactions and C60 being the n layer, amongst other reasons. Thanks so much for your exciting videos!

Today, when there is so much science and engineering into everything, knowing that a solar panel is 25% efficient and not 50% or 70% it is just crazy (due to what we are used to nowadays). I am sure I will be alive when someone finds a solution to the efficiency problem and goes from 25% to 60%, and later, maybe better, reaching 80% or 90%

Yeah I've been hearing about the dream of solar since I was a kid. Every year or two I see some new breakthrough that promises to advance the tech exponetially and place it within the grasp of average citizens. Then shortly after, that particular advancement either turns out to be bogus or info about it dries up with no explanation. Now I'm nearing the end of my life and we're still miles away from it being affordable enough up front and efficient enough to foreseeably make the jump to being a viable complete replacement for traditional energy systems. It seems the only tech that does advance and get implemented into society are those that cost us more and are designed to worm themselves into invading our privacy and further controlling our lives. I don't expect any sort of advancement like this to come to fruition before I'm gone, if ever. Good luck to future generations but don't hold your breath for energy utopia.
