Abstract

We report on design considerations for developing dilute nitride solar cells with back surface reflectors. Two different scenarios including specular and diffuse reflectors were modeled and their effects on solar cell characteristics were compared with cells without reflectors. We show that for optimal performance of the solar cell with back surface reflectors, the layer structure of the cell has to be optimized taking into account the reflector properties. Using high quality reflectors the usable background doping range for GaInNAs sub-junctions can be extended to above 1×10 16 cm -3.
