Paint your own solar cells

InnovaLight, a Californian start-up, is developing light-activated power generating. Silicon ink could lead to a way cheaper manufacturing. Fraunhofer Institute in Germany has been working on nanocrystalline dye (PDF) and organic solar cells for some years.

These cells convert sunlight to electricity with the help of dye, carbon and polymer molecules. Both areas of research are still in the early stages and face technical challenges like keeping the chemicals stable and sealing the solar cells.

In future it could be possible to paint cars with such a silicon paint. Invisible to our eyes, cars could be “rolling solar cells”. “According to Burke, the ability to solution-process the dots in a so-called silicon ink could lead to cheaper manufacturing. ‘You now have the potential to produce thin-film photocells which lends itself to high-throughput manufacturing using existing roll-to-roll printing technology,’ he said. ‘Our modelling indicates that there will be substantial improvements in cost versus how silicon is used today.’Solution-processing also means that InnovaLight can deposit its silicon nanocrystals onto flexible substrates. This opens up a vast array of markets from consumer applications such as clothing to charge up portable electronics through to flexible battery chargers for the military.”

    What would you say if I told you that you can save almost 40% on your gas costs just by adding tap water.
    Interested in learning more on how YOU CAN REALLY USE TAP WATER TO SAVE FUEL!!

    Solar Battery Chargers come in hand when you are on the go. Who would’ve thought? Silicon Solar has different and lightweight Travel Solar Battery Chargers from Ipod Chargers to Laptop Chargers.

    cool blog!!! I like this one and . I love all the solar issues. Keep up the great work our planet deserves it. It’s been great to us and let’s be great to it. It’s everybodies duty to chip in and help mother earth. Alternitive energy is the least we can.
