LUMINESCENCE CONVERSION AND APPLICATION TO PHOTOVOLTAIC ENERGY CONVERSION

摘要

A system for solar energy conversion using the up or down conversion of sub-band-gap photons to increase the maximum efficiency of a single-junction conventional solar cell is discussed. Different embodiments show the up or down converter (15) between a solar cell (13) and a reflector (16). This structure may be doubled to include converters on both sides of the solar cell. Optional insulator (14) may be placed between the solar cell and the converter. The reflector reflects the radiation back to the solar cell and converter to allow more uptake of available radiation.
