Abstract
The single, double absorbers-based perovskite solar cells (PSCs) have attracted considerable attention of researchers in the past few years due to their promising photovoltaic parameters. The present work discusses a comparative performance analysis of the two configurations, namely the ITO/C 60 /MAPb(I 1– x Cl x ) 3 /CuSCN/Au, ITO/C 60 /MAPbI 3 /CuSCN/Au, and ITO/C 60 /MAPb(I 1– x Cl x ) 3 /MAPbI 3 /CuSCN/Au composed of a single layer of perovskite as the absorber and a double layer of two different halide perovskites as absorber materials, respectively. The MAPb(I 1– x Cl x ) 3 -based PSCs provide lower performance parameters when compared with the performance of MAPbI 3 -based PSCs and limit their output for photovoltaic applications. Nevertheless, the need to find maximum absorbance due to the novel grading approach leads to absorbing a wider quantity of light spectra, boosting efficiency. SCAPS-1D, as a software simulator, is used to examine our proposed models. The optimal output parameters obtained in this simulation are J SC of 21.41 mA/cm 3, V OC of 1.278 V, FF of about 88.03%, and PCE of 24.10%, respectively.
