Preparation of CdS/InP solar cells by chemical vapor deposition of CdS

Abstract
CdS/InP heterojunctions are grown by chemical vapor deposition of CdS on InP in an open-tube H2S/H2 flow system. The importance of H2S admixture for the etching and cleaning of the InP surface is demonstrated. The solar cell has an open-circuit voltage of 0.78 V, fill factor of 0.75, and a power conversion efficiency of 13.5% for AM2 conditions.
