    Hopefully we can keep moving with this momentum. The world needs this change, for ourselves and for our planet.

    If different layers are put to absorb photons of different wave lengths in the color spectrum, including radio waves and radiation, I am sure 100% efficiency can be achieved from solar panels.

  3. mihindu1967 on December 7, 2020 at 9:57 pm

    Some years ago on Yahoo news I saw an article about a research being done to make the surfaces of the solar panels like the surfaces of blue ray DVD. What ever happened to that research? The article said that due to high cost of production, such panels are not practical. Why? What is the price of a empty blue ray DVD, and solar panels would be a collection of them! I have a proposition. Why not transfer the technology to China where they can manufacture things whole lot cheaper. America may have invented the mobile phone, but if it isn’t for China not each and everyone of us would have a mobile phone in our hands.

  4. Randall Parr on December 7, 2020 at 10:00 pm

    I hv 36 LG solar panels averaging about 1000 mwh per month though mostly in summer (q2 & q3) – 13k
    kwh / year happy with them

  5. The Firehawk on December 7, 2020 at 10:00 pm

    I like solar but why the f*** aren’t we using nuclear for almost everything already? It’s so much better in terms of pollution and availability and cost while matching safety.

    Czech already pass 41%… what you talking about NEW tech si nonsence.. 41%+ efi. pantented in my country 4year back.. if you go higher.. material get burn and you destroy cell it was stable limit of all chemistry we have.. dont forget CZ is mastermind of nano-technology.. there is no one beter! NO ONE!

    Very interesting, what do you know about the solar windows?, I know Richard Lunt from Michigan state university has come up with this sort of solar power but wondered if any companies are producing this product yet?. Cheers Mark.

    I think right now is the BEST time to buy Tesla Solar with federal tax going to decrease from 26 to 22 percent. Also if you do loan with prepayment (how much credit you get) you may not even have to spend any money out of the pocket and will save monthly on your bill. It’s a win-win situation.

    I personally bought the solar today and have a referral code to get $100 off if anyone wants it.

    Referral Code for 1,000 Free Supercharger miles. (1500 km) OR $100 off Solar

    Referral Code: gary78189

    Please DM me for Tesla questions or anything else ;).

    solar panels seem to be imitating the leaves of a tree more and more.

  12. Eric Fleet on December 7, 2020 at 10:05 pm

    While impressive, the cost of solar panels is about 25% of the cost of a home solar system installation. Bringing efficiency up will help, especially if it does not cause the cost of panels to go up. But ultimately until the cost of installations come down, solar will only be viable where there are large subsidies or in very favorable climates.

    This is glorious, I’ve been looking for "how much do you save with solar energy" for a while now, and I think this has helped. Have you heard people talk about – Aanarter Exceptional Ascendancy – (search on google ) ? It is an awesome one off product for discovering how to learning how to get free power without the hard work. Ive heard some interesting things about it and my partner got amazing results with it.

    In my experience most panels don’t last more than 15 years at best.

    Sounds like a scam to me. If this ever get out of the "lab", I’ll be suprised. I hope I’m wrong but I doubt it.

  26. Joe Botelho on December 7, 2020 at 10:23 pm

    The one with hundred layers, is it flat? Could you amp the light hitting it if it were full of curves?so the lightwaves would refract to another area of the panel, so on and so on?

  27. T. on December 7, 2020 at 10:24 pm

    I think renewables are a scam (okay, not completely), but they are way too overhyped than they need to be due to Elon Musk primarily romanticizing the idea of having a solar roof and paying nothing for electricity. Nowadays, low carbon emissions and maybe the price are all the advantages of solar energy (or really any other renewable energy) vs. coal. Nuclear takes the cake in EVERY single category over renewables. I challenge anyone here to name ONE category renewables are better at than nuclear.

  28. Peter Milanovski on December 7, 2020 at 10:26 pm

    You didn’t mention thin film amorphous solar panels, I don’t know what their efficiency is at and I don’t know if they are made large enough to use on a house roof, but they are being made and you can usually find them wherever auto parts are sold, some have USB ports and others have a cigarette lighter plug to keep the car battery topped up, the beauty of these things is that they will generate with ambient light! In other words, it will produce even in the shade, indoors under a light bulb! The panels usually come in 5W which isn’t much but can charge a phone from just being up against a window! They are not expensive so if you got two of them, you get a faster charge, or you can charge a phone battery bank all day while you are at work and it should be fully charged by the time you get home! Like I said earlier, it’s not a lot of energy but every little bit adds up over the year. You can tell which panels are thin film amorphous, the cells are a dark red to brown colour and they are not affected by shade like normal panels, you can literally cover 90% of it and it still will produce! Might be worth looking into!

  29. ER on December 7, 2020 at 10:27 pm

    The overview is somehow misleading as nowadays produced silicon modules are in the meantime made of app. 90% mono-Silicon. And thin-film is mostly non-Silicon.

  30. Thomas Körtvélyessy on December 7, 2020 at 10:29 pm

    hello @Kurzgesagt … another interesting source: care to research a little more? 😉

    Great video. Solar has amazed me, since my first project I built from parts sourced at my local Radio Shack. [Yes, I"m old.] Years ago I read a bout innovations in solar windows, and there is even a company called Solar Window Technologies that just fabricated a ‘film’ [in South Korea that is] to put on windows that produces voltage. It made me wonder what they could do if 1) It really works. and 2) It could be put on all those skyscrapers in Houston. To me that would be much better than eliminating windows. Thanks again for this video. Really enjoy keeping up with this technology and these innovations.

  33. thomas aquinas on December 7, 2020 at 10:30 pm

    There used to be solar water heaters in use in the deep South. Why we don’t have mandated solar roofs below the Mason-Dixon line is bewildering to me, especially now with the available battery backup that can save excess daytime power for night usage…

  34. Flavius Tech on December 7, 2020 at 10:31 pm

    In 2013 they said in 2 years perovskite solar panels will be in production. 7 years passed and they still saying in 2 years they go into production :). You said they will be cheaper, but if they put multilayer with monocrystaline and perovskite combined, how that panel could be cheaper? 🙂

    if this applies to Africa, then they don’t need to pay for electricity anymore other than periodical maintenance.

  37. Love Capitalism No socialism on December 7, 2020 at 10:35 pm

    Solar is just not worth it the 20 to 30 your pay off until you even start making any money back seems ridiculous especially having all that junk on your roof and we don’t even know with the lifetime and the warranty of the product will really be when these places likely be out of business 20 years from now when the systems are completely useless and broken. you have to factor in the price to remove the systems off the roof repair of the roofs you’re not gonna make any money in the end

  38. Mark Jones on December 7, 2020 at 10:35 pm

    4:30 so it’s not as durable and will fail in half the time of conventinal solar panels meaning the net gain is ZERO! sorry every year for the last 10 years some new article says this is the next big thing in solar and every time it is just vapor ware.

  39. Eric CLOUD Bolduc on December 7, 2020 at 10:36 pm

    Where can I get a $13 100w panel(13 cents per watt)? I have been overpaying by a lot.

  40. TankingShaman on December 7, 2020 at 10:37 pm

    Join the Dark Side, we harness power of shadows.

  41. Bishwa Nath Singh on December 7, 2020 at 10:38 pm

    You should also tell about the price of Perovskite Solar Cell.

  42. Justwantahover on December 7, 2020 at 10:41 pm

    The shadow device could be used on solar cells under wind turbines where the blade shadows pass constantly (when there is wind).

  43. first last on December 7, 2020 at 10:46 pm

    You said clouds stop solar energy production with photovoltaics, but that’s not true, it just reduces it.

    Let’s see now………. by 2030 we should have about 2 trillion solar cells worldwide that need recycling but there is no one wanting to do it? So we drive by the junk yards with panels piled a quarter mile high waiting to be dumped in a landfill but nobody wants to take them? Our genius perfect solution is turning into a nightmare? Why didn’t somebody tell us about what lay in the future? Does this scenario sound familiar? It’s happened dozens of time in past!

  48. The Firehawk on December 7, 2020 at 10:52 pm

    The shadows one is just stupid, normal PV panels already produce in the shadow, even moonlight, the problem is that the converters and chargers cannot work with the low voltages, the solution is to have a low voltage automatic controller to switch the array from more panels in parallel to more panels in series, but for some reason this isn’t done yet, I suppose the benefit in energy production maybe outweighs the prodution benefit?

  49. SoloSailor on December 7, 2020 at 10:52 pm

    AND efficiencies in power CONSUMPTION in the average house should come FIRST !
    Chest top loading freezers are just step #1
    Geo cooling, Vacuum panel insulation, etc is still cheaper than buying more than a Roof Top of solar panels, an EFFICIENT home doesn’t even need.
    Its SO frustrating hearing people being "SOLD" on panels, while ignoring home efficiency entirely because efficiency doesn’t generate direct new SALES.
    my system is over 2 decades old and now is too much power because all the appliances and structure have been updated to high tech. It’s all super DIY easy
