Identifying the relationships between subsurface absorber defects and the characteristics of kesterite solar cells

Carbon Energy, 2023
Understanding the defect characteristics that occur near the space‐charge regions (SCRs) of kesterite (CZTSSe) solar cells is important because the recombination loss at the CZTSSe/CdS interface is considered the main cause of their low efficiency ...

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.
