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.

RF Electromagnetic Field Treatment of Tetragonal Kesterite CZTSSe Light Absorbers [PDF]

Nanoscale Research Letters, 2017
In this work, we propose a method to improve electro-optical and structural parameters of light-absorbing kesterite materials. It relies on the application of weak power hydrogen plasma discharges using electromagnetic field of radio frequency range, which improves homogeneity of the samples. The method allows to reduce strain of light absorbers and is
