A comprehensive numerical analysis for a lead‐free perovskite solar cell (PSC) has been carried out using device simulation software. Various factors affecting the solar cell's performance have been investigated for device optimisation; more specifically optimisation of device buffer and the absorber layer. Different design strategies for optimising the power conversion efficiency (PCE) through solar cell capacitance simulator numerical simulation have been proposed. Enumerated study of the effects of thickness, band gap, light illumination and defect area on the PCE is carried out. In this study, two types of configurations (La 0.7 Sr 0.3 MnO 3 /zinc oxide and La 0.7 Sr 0.3 MnO 3 /Nb:SrTiO 3 ) are simulated which gives highest conversion efficiency of 11% at 600 nm and 32% at 350 nm wavelength. The impact of defect density has also been addressed to analyse the performance of cell module. The optimisation of device parameters pinpoints enormous potential for the enhancement of conversion efficiency of high‐efficient PSC.
