Phys. Rev. B 76, 085303 (2007) [8 pages]Reciprocity relation between photovoltaic quantum efficiency and electroluminescent emission of solar cellsReceived 21 September 2006; revised 18 June 2007; published 2 August 2007 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. © 2007 The American Physical Society URL:
