Solar energy is one of the most important methods used worldwide to provide some of the global energy requirements. It is easily available and free from negative effects on the environment. In this research, the possibility of increasing the efficiency of solar cells is investigated. The SCAPS-D simulation is used to investigate the ZnO/ZnS/CNTS solar cell. The practical research is compared with the program, showing that the program simulates the reality due to the high convergence between the practical and theoretical results of the program. By changing the doping ratios of the theoretical cell layers, the cell efficiency shifts from )3.19%( to )9.41%(. The theoretical cell is improved by adding various back reflection layers (BSL), increasing the conversion efficiency from )9.41%( to )11.59%(. After adding more matching layers, the cell's structure becomes ZnO/ZnS/V2O5/CNTS, increasing the conversion efficiency to (14.25%). The ratio of conversion efficiency of ZnS/V2O5/CNTS/CFTS is (17.22%), the filling factor (67.74%), the short circuit current (23.247mA/cm2), and the open circuit voltage (1.0937 V).
