Low-cost solar energy capture. The market for solar energy has stalled due to the high cost and low efficiency of current technology. Conventional solar cells do not produce power efficiently enough to justify the cost of investment. This project seeks to develop low-cost, thin-film silicon photovoltaics with high efficiency that could be used to realize the full potential of solar energy. Research indicates that there is a potentially lower-cost approach to manufacturing silicon photovoltaics by utilizing layers of thin-film silicon in an enhanced cell design.
