   It was your earlier solar panel videos that originally brought me to this channel, so I'm always fascinated with new developments.

   Please no! Why am I getting the autotranslated audio? It sounds so wrong. How do i turn that off?

   If we had a milliwatt hour of electricity for every time some new technology was going to revolutionize solar cells our energy problem would be solved overnight.

   Absolutely fascinating. Can't wait to see where this tech ends up in ten years. This is my first timr hearing about it.

   Im sure one way or another solar technology will improve by leaps and bounds over the next 25 years.

   Imagine durable solar film that can be applied to vehicles to power them indefinitely, paired with better and lighter battery storage… Small films applied to any device, appliance or water purification machine….

   And of course buildings. Im sure in 50 years we'll get there.

   Interesting tech, but solar panel efficiency doesn't really matter as much as how much battery capacity you need to keep the lights on during the night.

   Worth to mention that Poland has launched a factory that produces perovskite flexible solar panels, sauletech 😊

   I have seen the “This COULD change Solar forever!” videos since the 1990s. lol

   The statement should be made this way “This could NOT change Solar forever!” 😆

    Why is there so little rational discussion about the current and future social and environmental externalities of solar energy implementation? Personally, I prefer solutions that can generate energy from highly energy-dense sources, using the least amount of materials and requiring minimal future interventions. This approach ensures the lowest possible amount of actualized externalities.

    So, Quantum Dot tech is on the verge of rendering $200,000 investments in PV systems redundant;
    Question remains: will PV manufacturers vulture the QD patents, rendering QD Unobtainium… not entirely unlike energy monopolies creating municipal "Permitting Hell", with PV Tech…
    (Fossil Fuel Gigantuim, notwithstanding)

    Imagine using quantum dots solar panels in shade of multi-substrate solar panels. We have been having issues of stacking solar panels for a decade, this might work.

    I heard/saw this once this breakthrough came out. However, I quickly dismissed it by comparing the cost of quantum dot OLED TV vs none. The difference is substantial around $200-$300 of the same sized TV. A huge solar panel that is around 6 x 3 ft at 500 watts is just $100 or less in China. In other words, quantum dots alone costs more than a solar panel.

    @johnhopkins6260 1年 ago

    Passing thought (aka "brain phart): with Ecoflow Balcony/micro units, could generally circumvent municipal "permitting Hell", by providing most household electrical needs via Ecoflow units… will still need to satisfy mandated Energy Industry monopoly tyranny, with a minimized connection/usage… until municipal Nazis kick down your door to "investigate".
    FWIW, currently, EcoFlow CLASSIC PLUS DELTA 2 balcony photovoltaics, in Poland, runs about $2000, and is NLA

    I think this is stupid, or perhaps. very stupid.
    people cant be controlled with electrical energy.. failed bigtime.
    the so called duck curve, is evidence people are a collection of half idiots.
    no body is willing to pay for elevated price of energy conversion.
    if people are so organized… WHY THERE IS A DUCK CURVE???
    isn't it possible to build massive energy storage systems and transfer the energy?
    BUT NO.. IS NOT HAPPENING… THE DUCK CURVE IS BECOME MORE EXTREME.
    or why don't big plants reduce power??? BUT NO.. THAT INCREASE MAINTENANCE, AND LESS MONEY.

    is not a WIN-WIN scenario.
    what is profit for home owner solar installation, is loss for big plant if they reduce power.
    is the other way around… big plants need MORE MONEY TO STAY HEALTHY, not LESS MONEY.

    somebody will get FIRED.. because of this increased efficiency.
    WHY WOULD THAT PERSONAL COME BACK TO RAISE POWER IN THE BIG PLANT???
    NOW THAT IS A GOOD QUESTION.
    I THINK.. NOT.. WILL NOT COME BACK.

    thus.. electrical system, is FINANCIALLY HIGHLY UNSTABLE.
    thus.. electrical system, is FINANCIALLY HIGHLY UNSTABLE.
    thus.. electrical system, is FINANCIALLY HIGHLY UNSTABLE.
    thus.. electrical system, is FINANCIALLY HIGHLY UNSTABLE.

    quantum dots will change the world… IF BIG PLANTS ARE WILLING TO LOSE MONEY, TO REDUCE POWER.
    quantum dots work fine in a lab… but in real world scenario.. is a tug of war with consumers.

    electrical revolution, probably will fail.. electrical system is financially very unstable.

    is evidence… against the system.

    These could be a game changer in specific applications, such as solar powered vehicles maybe, but usually I'm under the impression that we have enough space for adequate amounts of solar panels. I'm more looking forward to innovations like sodium ion batteries.

    @johnbarker5009 1年 ago

    The idea that solar panels could one day be twice a efficient with little difference in cost is very impressive.

    @brentsmithline3423 1年 ago

    Does not sound good for quantum dots in the solar panel field.

    @sirkingjamz101 1年 ago

    Sounds like i can finally have a colourful solar panel!?! ok im in 🙂

    @eyewonder6448 1年 ago

    How about a solar powered Stirling hot air engine?
    Low maintenance, easy to build and reliable.

    @aussie2uGA 1年 ago

    I remember when OLED was proclaimed to be the low cost answer to a better TV. All of that promise when to profits though when marketing made it a premier product to have.

    @lina4469 1年 ago

    Will this help with how toxic solar panels are when at end of life?

    @MichaelRainabbaRichardson 1年 ago

    Re: ecoflo versus a generator. One can back you up for a day or two while the other can back you up as long as you can get fuel. These two are not equivalent no matter the benefits of battery backup. If you really want to prepare for an outage, you would need this and a generator to keep the charge up over time. 😔

    @TwoBitDaVinci 1年 ago

    Great video Matt! I've always heard of quatum dots for new TV Displays, but hadn't thought about their application in solar! If we can figure out a non toxic long lasting blend, it would be such a game changer!

    @Woot-Zee 1年 ago

    Lool! Sure! Another potential! :))

    @nigelwitham2110 1年 ago

    There’s a British company called
    Nanoco who produce non-toxic cadmium free quantum dots and own a lot of IP in this area. They were spun out of research at Manchester University and their technology is used in Samsung TVs.

    Thanks for your hard work!

    ImHO Quantum dots sounds like a stupid name for crystallized molecules organized in precise pattern to function. As a highly efficient diode chain.
    I’m just against calling everything quantum.
    Just because there are many of the crystalline semi conductors.
    Why not crystalline diode array or something more descriptive?

    If a solar cell is just an LED working in reverse, why can't you charge your phone by putting the screen in the sun?

    I predicted "multi spectral photophotaic" solar energy well over 30+years ago while working at NASA. Almost there. Almost there…..

    10 nm quantum dots? I have a hard time grasping that size. what is that in inches?

    @ChrisJones-qo8le 1年 ago

    What we need to develop is direct energy conversation from heat to electricity thus solving two problems with one solution if the band gap can be tuned or a material created that cools things and makes power the world could change

    For some reason this video played back with german sound.. uff that was horrible

    @eideticgoone7035 1年 ago

    I enjoyed the video, but was bugged a little by your pronunciation of exiton. Here's what I found. 'How to pronounce exciton': https://www.youtube.com/watch?v=dfsRfjemrjg My cousin who was a professor of physical chemistry at Stanford taught me about these. Maybe there is more than one pronunciation.

    @davocc2405 1年 ago

    I do like the notion of something that lets only certain wavelengths through – could this be used to preclude infrared from panels to reduce their overheating and subsequent impacts on efficiency? Wondering if this could result in a film or cover for existing panels in really hot climates.

    @bobbastian760 1年 ago

    They're solving a problem that isn't the main problem with solar.
    Efficiency isn't the problem.
    Solar is intermittent, that's why it can never work for grid power without extremely expensive and polluting fossil fuel backup, or power storage tech which is currently not feasible.
    Nuclear is the solution, period.

    @kccreationsgaming 1年 ago

    Awesome! I learned about something similar to quantum dots, last year, regarding an impressive Barium Sulfate paint that has remarkably high emissivity to prevent heat transfer.

    It's non-toxic, the materials are widely available, and with a bit of precaution, can even be produced at home. Essentially, you make multiple solutions of barium sulfate with varying sized multi-micron spheres, similar to the quantum dots. When mixed together, the different sized orbs have a sort of exponential fractal effect on energy attempting to pass through it.

    For any interested, I learned it from the youtube channel "Tech Ingredients" in a video called:
