During preparation of compound semiconductor thin films undesired secondary phases and inhomogeneities may occur. Therefore, process control and monitoring are important aspects towards thin film optimization. In this study, white light reflectometry

Photoluminescence (PL) is commonly used for investigations of Cu2ZnSnS(e)4 [CZTS(e)] and Cu(In,Ga)Se2 (CIGS) thin film solar cells. The influence of interference effects on these measurements is, however, largely overlooked in the community. Here, it

The influence of composition on the quaternary Cu 2 ZnSnS 4 (CZTS) absorber material on the secondary phase content, recombination characteristics and solar cell performance is investigated. Best solar efficiencies are found in a very narrow Cu-poor,
