A Numerical Approach to Analysis of an Environment-Friendly Sn-Based Perovskite Solar Cell with SnO2 Buffer Layer Using SCAPS-1D

Abstract

In this research, we have proposed a Sn-based perovskite solar cell using solar cell capacitance software. The main aim of this study is to develop an environment-friendly and highly efficient structure that can be used as an alternative to other toxic lead-based perovskite solar cells. This work performed a numerical analysis for the proposed (Al/ZnO/SnO2/CH3NH3SnI3/Ni) device structure. The absorber layer CH3NH3SnI3, buffer layer SnO2, and electron transport layer (ETL) ZnO, with aluminium as the front contact and nickel as the back contact, have been used in this simulation. Several analyses have been conducted for the proposed structure, such as the impact of the absorber layer thickness, acceptor density, defect density, series and shunt resistances, back contact work function, and operating temperature. The device simulation revealed that the optimum thickness of the absorber layer is 1.5 μm and 0.05 μm for the buffer layer. The proposed Sn-based perovskite structure has obtained a conversion efficiency of 28.19% along with FF of 84.63%, Jsc of 34.634 mA/cm2, and Voc of 0.961 V. This study shows the upcoming lead-free perovskite solar cell’s enormous potential.

Design and Simulation of an Environment-Friendly ZrS2/CuInS2 Thin Film Solar Cell Using SCAPS 1D Software

“…At the Electronics and Information Systems (EIS) Department at the University of Gent in Belgium, the "Solar Cell Capacitance Simulator One-Dimensional" (SCAPS-1D) application was developed to model solar cells. [12]. Te continuity equation and Poisson's equation are given for the free electrons and holes in the conduction and valence bands [13].…”

Enhancing efficiency of Sb2Se3 solar cell through optimized optical and electrical properties with Bi-layer absorber

“…CZTS is a novel p-type material with a band gap of 1.5 eV and outstanding material properties, with an absorption coefficient of 10 4 cm −1 , equivalent to CIGS [15]. CH 3 NH 3 SnI 3 is a tin-based organic-inorganic hybrid perovskite that is a variant of the well-known and thoroughly investigated CH 3 NH 3 SnI 3 , in which lead (Pb) replaces tin (Sn) because Sn 2+ is a non-toxic cation in comparison to Pb 2+ ions, it is highly recommended for usage in halide perovskite solar cells due to its good photoelectric performance and compatibility [16]. From the table 1, ZnO/i-ZnO/CH 3 NH 3 SnI 3 /Sb 2 Se 3 configuration demonstrates higher solar cell efficiency and overall improved performance compared to the CZTS/Sb 2 Se 3 /NiO structure.…”
