Abstract
In this study, we designed and simulated a new double absorber perovskite solar cell device by performing numerical analysis using SCAPS-1D. The architecture of the solar cell device consists of Glass/FTO/C2N/CsSnGeI3/CsSnI3. Optimizing the core parameters of CsSnGeI3 implied to an encouraging solar cell performance with a remarkable power conversion efficiency of 28.61%. The results show that increasing the thickness of CsSnGeI3 to 1000 nm enhances the solar cell performance. The simulations show that increasing the absorber layer thickness is desirable to promote the spectrum absorption process, thus accelerating the generation rate of the charge carriers. Increasing the doping density in CsSnGeI3 implied to inconsistent impact on the solar cell performance. The solar cell displayed the optimal performance at low and high doping level, while at intermediate doping level, the solar cell efficiency depreciates to 23.18%. This result is ascribed to creation unstable depletion regions at this doping level, which prevent the charge carriers from reaching the metal back contact. Additionally, increasing the defect density in CsSnGeI3 yielded a sharp continuous degradation in the device performance. The power conversion efficiency decreased to 15.22%. Finally, increasing the operating temperature showed a harsh impact on the solar cell performance, and the optimal performance occurs at 300 K. It is believed that the simulated model represents an added value and a great potential in the field of solar cells research and fabrication.
