Photovoltaic (PV) systems are a promising alternative to fossil fuels for meeting the increasing energy demand of society. This project focused on analyzing alternative materials indium (III) sulfide (In2S3) and CZTS as the buffer and absorber layers, respectively. Both layers were deposited using electrodeposition with a three-electrode electrochemical cell. The goals of this project were optimizing the deposition parameters for CZTS and synthesizing an n-In2S3/p-CZTS PV device to analyze its performance parameters. The results revealed the CZTS films had copper-rich, zinc-poor characteristics, giving inconsistent absorption values. In addition, depositing In2S3 on top of CZTS on Mo-coated glass proved challenging due to its high deposition temperature.
