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.

Analysis of the Voltage Losses in CZTSSe Solar Cells of Varying Sn Content [PDF]

The Journal of Physical Chemistry Letters, 2019
The performance of kesterite (Cu2ZnSn(S,Se)4, CZTSSe) solar cells is hindered by low open circuit voltage ( Voc). The commonly used metric for Voc-deficit, namely, the difference between the absorber band gap and qVoc, is not well-defined for compositionally complex absorbers like kesterite where the bandgap is hard to determine.
