Polycrystalline thin-film InP/CdS solar cell

Abstract
We report the preparation of a polycrystalline thin‐film InP/CdS solar cell of area 0.52 mm2 having a power conversion efficiency of 2.8% under AM1 conditions. Based on the current‐voltage characteristics, we estimate that development of an improved contact to the p‐type InP would result in substantially higher efficiencies without any further improvement in the InP/CdS interface.
