Abstract
Anomalous photovoltage in polycrystalline Cd0.25Zn0.75Te thin films ha s been studied. The effect is described as a combined effect of mainly p-p(+) junctions at the grain boundaries and surface band bending apa rt from other factors. A new method has been developed to enhance the photovoltage by placing a fine mesh in front of the substrate during t he film deposition. This enhancement of photovoltage is explained with the help of a trap-induced space-charge model.
