Effect of Al2O3 Dot Patterning on CZTSSe Solar Cell Characteristics
Nanomaterials, 2020 In this study, a 5-nm thick Al2O3 layer was patterned onto the Mo electrode in the form of a dot to produce a local rear contact, which looked at the effects of this contact structure on Cu2ZnSn(S1-xSex)4 (CZTSSe) growth and solar cell devices.

Synthesis of large CZTSe nanoparticles through a two-step hot-injection method [PDF]
, 2015 Grain boundaries in Cu2ZnSn(SxSe1x)4 (CZTSSe) thin films act as a defect that reduces the mobility of the charges. Hence one way to improve the performance of these thin film solar cells is to increase the grain size in the films.

Numerical simulation of SnS/CZTSSe heterojunction solar cells
Journal of Ovonic Research, 2023 This work combines the advantages of SnS and CZTSSe to constitute the SnS/CZTSSe heterojunction solar cells, and the effects of various factors on cell performance were studied by using numerical simulation. The results show that the optimal thickness of CZTSSe and SnS are 0.1 μm and 2.0 μm, respectively.
