Gallery: Spray-On Solar Cells Energize Almost Any Surface


Bulky and expensive photovoltaic panels are so 2008. What does the future look like? Entire buildings, rooftops and even windows spray-painted with revolutionary nanoparticle inks that channel solar power into a thin, semi-transparent and relatively inexpensive medium. Sound crazy? Not at all, according to one group of chemical engineers.

    Is it a new way for solar energy? It will a progress for the solar energy process.
    I have many technical question about the solar spray-on.
    I communicate and i find opportunity to innovant technology in France, and i will very please to get more informations.

    This spray-on solar paint sounds like it’s definitely something to keep our eye on.

    The application of such a product is simply astounding. And three to five years on the solar horizon will be here quicker than we think.

    I’m actually looking forward to see how this technology will evolve over the next few years.

    Check out a company called Nanosolar. They are privately owned and have been doing this for years. They won the popular Science Innovation of the year in about 2007

    Since the photocell coatings are usually dark in color, they will heat up the surface of the roof while working. There are coatings available from SPI that will be applied first and the photocell coating applied over them to block this heat loading into the building while it is working.

    I love this concept. Between cellphones and MP3 players we can always use a new power source. This brings it anywhere. Anytime.
