Printed solar cells. Solar energy at a tenth of the price.

Ordinary solar cells are pretty complicated technology, even though the theories behind them are reasonably simple. They will also be expensive since the manufacture gets pretty much as complicated as the tech. Now, however, a couple of companies have presented ideas for the manufacture of solar cells that in principle means that they can be printed on a thin metal film. Since manufacture with the printing method would resemble an ordinary printing press, the cost could be a tenth of what is the case today, and they could make solar energy available to more, and cheaper than fossil fuels. One of the companies is American Nanosolar, who recently were awarded Innovation of the year by Popular Science magazine.brbr
