AMORPHOUS SILICON SOLAR CELL ALLOWING INFRARED TRANSMISSION

摘要

An amorphous silicon solar cell (11) with a layer (14) of high index of refraction material or a series of layers having high and low indices of refraction material respectively deposited upon a transparent substrate (12) to reflect light of energies greater than the bandgap energy of the amorphous silicon (20) back into the solar cell and transmit solar radiation having an energy less than the bandgap energy of the amorphous silicon.
