 Search for more abundant, lower cost materials should help improve solar cost efficiency

Solar power is an incredibly promising alternative energy technology.  However, the problem with converting solar energy directly to solar power via photovoltaics or other designs is that the cost of producing power is simply not cost competitive with nature's designs -- coal or petrol.

The cost issues are not for lack of efficiency.  Scientists have milked very high efficiency out of the cells, iteratively raising the yield year by year.  However, the high cost of silicon, the primary material for solar panel cells, keeps the costs high even as efficiencies experience dramatic gains.
In order to make solar cost competitive, researchers at University of California, Berkeley, and the Lawrence Berkeley National Laboratory (LBNL) are spearheading the search for a silicon replacement for the solar industry. [Comments...]
