SolarWindow with Clear Spray-On Film Could Generate 300% More Energy Than Solar Panels

In recent months, we’ve seen a lot of companies developing new technologies for solar cells to create energy-generating windows. Most are small squares that have to be manufactured in a temperature controlled lab vacuum, but New Energy Technologies has unveiled SolarWindow, a working prototype that is simply sprayed with the company’s eco-friendly electricity generating film to produce energy. The company estimates that when applied to the facade of an office tower, the windows could generate 300 percent more energy than solar panels mounted on a building’s roof.

Details about the product’s make-up have not been released, but New Energy stated that the film replaces the visibility blocking metal used in most solar panels with eco-friendly compounds. The film is 1/10th the thickness of current thin films, which allows the glass remains to transparent. It can generate electricity from natural and artificial light, and New Energy says they perform 10 times better than current solar film technologies.

New Energy sprays the film over the world’s smallest organic solar cells — smaller than a grain of rice — which allow the energy-generating film to be applied at room temperature and makes for inexpensive manufacturing. Because of their transparency, versatility, and eco-friendly compounds, the windows could be used in every type of building, from single family homes to office building skyscrapers.

WHY THIS MATTERS

While colorful and non-transparent solar cells and windows are great for commercial structures, they aren’t the best for residential buildings and private homes. A see-through, uncolored solar window like the one developed by New Energy could mean that all buildings could have energy-generating windows, without sacrificing access to natural daylight. Plus, the windows are cheaper and potentially more efficient than traditional solar panels.

    Hi Jaretogarato

    I understand your statement on underwhelmed .

    But to this moment in time Dyesol has used around 500 man years of research into DSC.

    Unfortunately I have seen three companies in the US claiming they have invented something similar to DSC.
    Well they have not, and I wonder what their Investors will think when they find out the horrible truth that they are using Dyes Dyesol gave up on 10 years ago.

    Dyesol-Timo in South Korea are actually manufacturing stand alone window mounted Heat Exchangers for every public building in South Korea. In a few months they start manufacturing stand alone street lights incorporating CEGS technology(see above)
    A similar product OPV is on sale on a lot of consumers items and G24i is the main manufacturer.

    But the big energy saver is Tata Steel Colors-Dyesol tin roofs which looks like ColorBond.
    This is a Game Changer and the stated aim is to get the price down to a $1 a Watt.

    A really smart person would read what is being said in the second paragraph especially in regards to Shotton ;)

    Great idea, and very suitable for many buildings, however, in the heat of the summer we tend to have our shutters closed to reduce the effect of the sun heating the house up.

    Interesting though that lighting your house at night could also provide a return in power.

    “Could this idea be adapted to green houses so they could power themselves? ”

    Well Yes

    DSC (Dyesol) can use a variety of different colored DYES and one day could work as a filter to let in the spectrum that is needed for growth, but get power from Photons (not necessary Sunlight but it still works) landing on the filter.

    Another Aussie Company (BLUGLASS) has come up with a way to put LEDS on normal Glass ,so I assume that could be used around the edges of each pane in a Hot House.

    Even better Dyesol have the Patent for CEGS which is a battery/capacitor that could be sprayed/screened on say under the Bluglass

    Not long ago a story like this would get me really excited. After many years of seeing such announcements and few new products on the market, I’m officially underwhelmed. What this story lacks is a time to market and estimated price point. Technology is cool potential power. Technology on the shelf that we can buy and use is cool actual power.

    .
    This product in my humble opinion is DSC or OPV.
    In both cases they will have to pay a licensing fee to EPFL and Michael Greatzell the Inventor

    If it is DSC then they will have to pay a licensing fee to EPFL and Dyesol

    Interestingly Dyetec Solar hold the Patents on the Transparent Conductive Glass and they will have to pay a licensing fee to Dyesol and Pilkington Glass

    Dyesol also have a huge pile of blocking Patents for all sort of variations on DSC

    Turning an entire building facade into an solar panel is a brilliant idea. For those tall buildings, there definitely have more facade surface than roof area.

    Could this idea be adapted to green houses so they could power themselves?
