Abstract

The ZnO/ZnS/ CNTS solar cell was studied using SCAPS-1D simulation. The cell efficiency was 9.38% and to improve the cell a back reflection layer (BSL) was added, so the conversion efficiency increased to 10.65% and we entered buffer layers, thus the cell structure became ZnO / Buffer / CNTS the conversion efficiency increased to 10.78%. It turns out that the effect of the buffer layer is greater than the reflection layer. The best cell was ZnO/CdS/CNTS/Cu2O and the conversion efficiency was 12.09%, fill factor 62.98%, short circuit current 20.01 mA/cm2 finally open circuit voltage 0.95V.
