it could happen soon, imagine your car parked in the sun with a plastic solar coating on the roof. Imagine every building surface generating clean electrical energy. Well, it could happen very soon (if hyperbolic sciencedaily press releases are to be believed, at any rate!).
In order to be considered a viable technology for commercial use, solar cells must be able to convert about 8 percent of the energy in sunlight to electricity. Wake Forest researchers hope to reach 10 percent in the next year, said Carroll, who is also associate professor of physics at Wake Forest.
Because they are flexible and easy to work with, plastic solar cells could be used as a replacement for roof tiling or home siding products or incorporated into traditional building facades. These energy harvesting devices could also be placed on automobiles. Since plastic solar cells are much lighter than the silicon solar panels structures do not have to be reinforced to support additional weight.
Screw ethanol, put all your energy into developing solar and wind energy, battery technology and electric vehicles. See how much better an idea that is compared to corn ethanol.
