Amorphous silicon solar cell allowing infrared transmission

Patent ·
OSTI ID:5861934

An amorphous silicon solar cell is described with a layer of high index of refraction material or a series of layers having high and low indices of refraction material deposited upon a transparent substrate to reflect light of energies greater than the bandgap energy of the amorphous silicon back into the solar cell and transmit solar radiation having an energy less than the bandgap energy of the amorphous silicon. 14 claims.
