nanosolar

A review of advances in solar panel technology and traditional polycrystalline silicon technology, with comments about advantages and disadvantages of these approaches. Problems with the Chinese silicon production industry are mentioned, as are successes in Germany and Spain. Links and references are provided.

Researchers at Idaho National Laboratory, along with partners at Microcontinuum Inc. (Cambridge, MA) and Patrick Pinhero of the University of Missouri, are developing a novel way to collect energy from the sun with a technology that could potentially cost pennies a yard, be imprinted on flexible materials and still draw energy after the sun has set.

Nanosolar with the help of the Google Guys has developed cheap solar panels that don't use silicon and are now bringing them to market. You can even buy one on eBay.
