Submission + - Superefficient Solar Cell from Silicon Nanocrystal 1
chinmay7 writes: "Researchers at the National Renewable Energy Laboratory (NREL), have shown that silicon nanocrystals can produce two or three electrons per photon of high-energy (blue and UV) sunlight. The small size of nanoscale crystals results in the conversion of this energy into electrons instead of heat. Solar cells made of silicon nanocrystals could theoretically reach more than 40% efficiency, compared to 20% efficiency of the best conventional silicon solar cells.
