Surface modification through air annealing Cu2ZnSn(S,Se)4 absorbers [PDF]

Thin Solid Films, 2017
Abstract Recent studies demonstrate that air annealing can have a positive effect on the device performance of Cu2ZnSn(SxSe1 − x)4 [CZTSSe] solar cells. In this work air annealing of the selenium containing CZTSSe is compared to the pure sulfide CZTS.

Growth and characterization of Cu2ZnSn(S,Se)4 thin films for solar cells [PDF]

Solar Energy Materials and Solar Cells, 2012
Cu2ZnSnS4 (CZTS) and Cu2ZnSnSe4 (CZTSe) with their band gap energies around 1.45 eV and 1.0 eV, respectively, can be used as the absorber layer in thin film solar cells. By using a mixture of both compounds, Cu2ZnSn(S,Se)4 (CZTSSe), a band gap tuning may be possible.
