Photoluminescence studies in epitaxial CZTSe thin films [PDF]

Journal of Applied Physics, 2016
Epitaxial Cu2ZnSnSe4 (CZTSe) thin films were grown by molecular beam epitaxy on GaAs(001) using two different growth processes, one containing an in-situ annealing stage as used for solar cell absorbers and one for which this step was omitted. Photoluminescences (PL) measurements carried out on these samples show no dependence of the emission shape on ...

Deposition of CZTSe thin films and illumination effects on the device properties of Ag/n-Si/p-CZTSe/In heterostructure

Journal of Alloys and Compounds, 2017
Abstract Characterization of Cu 2 ZnSnSe 4 (CZTSe) thin films deposited by thermal evaporation sequentially from the pure elemental sources and in-situ post annealing was carried out at 400 C under Se evaporation atmosphere. Another annealing process was applied in nitrogen atmosphere at 450 °C to get polycrystalline monophase CZTSe film structure ...
