Abstract
We introduce the concept of a photovoltaic band gap Epvg for amorphous solar cells. This is the minimum photon energy thermodynamically required for the generation, of two free carriers in an operating solar cell. For hydrogenated amorphous silicon the photovoltaic band gap is 1.57 eV at 1-sun illumination.Keywords
