A comparative study of proposed cells and comparison with the previously reported cells.
| Solar cell structure | VOC (V) | JSC (mA/cm2) | FF (%) | ⴄ (%) | Ref. |
|---|---|---|---|---|---|
| Cu/ZnO:Al/i-ZnO/n-CdS/p-CMTS/Pt | 0.883 | 34.41 | 83.74 | 25.43 | Proposed (Pristine cell) |
| Cu/ZnO:Al/i-ZnO/n-CdS/p-CMTS/p+-SnS/Pt | 1.074 | 36.21 | 81.04 | 31.51 | Proposed (Cell with BSF) |
| i-ZnO/n-CdS/p-CMTS | 0.88 | 24.10 | 77.90 | 16.50 | [6] |
| AZO/n-ZnO/n-CdS/p-CBTS | 0.78 | 11.64 | 74.77 | 6.9 | [53] |
| AZO/i-ZnO/CdS/CMTS/Back contact | 1.11 | 26.26 | 61.08 | 17.81 | [20] |
| AZO/i-ZnO/Zn (O, S)/CMTS/Back contact | 1.11 | 26.27 | 66.22 | 19.46 | [20] |
| AZO/i-ZnO/SnS2/CMTS/Back contact | 1.12 | 26.44 | 68.33 | 20.26 | [20] |
Herein, the CMTS absorber and SnS BSF have been demonstrated and utilized, which are inexpensive, economical, earth-abundant, and environmentally benign. However, these extensive simulation results revealed that the Cu2MnSn4 and SnS have strong potential as competitive photovoltaic materials with favorable band gaps for fabricating high-efficiency cost-competitive solar cells.
