Analyses of Local Open Circuit Voltages in Polycrystalline Cu(In,Ga)Se2 Thin Film Solar Cell Absorbers on the Micrometer Scale by Confocal Luminescence

Analyses of Local Open Circuit Voltages in Polycrystalline Cu(In,Ga)Se2 Thin Film Solar Cell Absorbers on the Micrometer Scale by Confocal Luminescence

Polycrystalline chalcopyrite absorbers in thin film solar cells exhibit distinct spatial inhomogeneities which are obviously introduced during growth of the grainy structure. Amongst several structural inhomogeneities in scale lengths of grains of one ?m or below, spatial variations of opt...
