The present study describes the computational analysis and optimization of lead-free build perovskite solar cells (PSC) using different hole transport layer materials (HTLM). The proposed new design explores the environmentally friendly tin based perovskite structure i.e., Glass/FTO/PCBM/CH3NH3SnI3/HTL/Au. The focus of this paper is to boost the efficacy of lead-free PSC by implementation of distinct HTLM. In addition, the efficiency of the photovoltaic cell has been exacerbated with the optimization of thickness of the absorber film, the defect concentration, interface defect concentration, the acceptordensity of the perovskite film and the quantum efficiency. The results have shown that with the use of Cu2O as a HTLM showed a remarkable efficiency of 28.57% compared to other hole transport layer materials. Finally, the results obtained make Cu2O as a potential candidate for the Tin based PSC.

Abstract


The present study describes the computational analysis and optimization of lead-free build perovskite solar cells (PSC) using different hole transport layer materials (HTLM). The proposed new design explores the environmentally friendly tin based perovskite structure i.e., Glass/FTO/PCBM/CH3NH3SnI3/HTL/Au. The focus of this paper is to boost the efficacy of lead-free PSC by implementation of distinct HTLM. In addition, the efficiency of the photovoltaic cell has been exacerbated with the optimization of thickness of the absorber film, the defect concentration, interface defect concentration, the acceptordensity of the perovskite film and the quantum efficiency. The results have shown that with the use of Cu2O as a HTLM showed a remarkable efficiency of 28.57% compared to other hole transport layer materials. Finally, the results obtained make Cu2O as a potential candidate for the Tin based PSC.
