Reciprocity relation between photovoltaic quantum efficiency and electroluminescent emission of solar cells
Uwe Rau
Abstract
A rigorous proof for a reciprocity theorem that relates the spectral and angular dependences of the electroluminescence of solar cells and light emitting diodes to the spectral and angular quantum efficiency of photocarrier collection is given. An additional relation is derived that connects the open circuit voltage of a solar cell and its electroluminescence quantum efficiency.
