Abstract
- The opto-electronic properties and solar cell efficiency of halide perovskites A <subscript>2</subscript> LiInBr <subscript>6</subscript> (A = Rb, Cs) are investigated using density functional theory (DFT) through WEIN2k and SCAPS-1D. The electronic characteristic of A <subscript>2</subscript> LiInBr <subscript>6</subscript> (A = Rb, Cs) compounds reveal their direct bandgap semiconductor nature and are active in visible rang. The results indicate that substituting Cs with Rb causes a slight narrowing of the bandgap. According to the optical analysis, these compounds possess dynamic visible-range optical properties that make them ideal for application in opto-electronic devices and solar cells. The A <subscript>2</subscript> LiInBr <subscript>6</subscript> (A = Rb, Cs) absorber layer is employed to simulate the solar cell efficiency of these lead free perovskite-based device. The optimized FTO/WS <subscript>2</subscript> /A <subscript>2</subscript> LiInBr <subscript>6</subscript> (A = Rb, Cs)/Spiro-MeOTAD/Cu solar cells exhibit the best performance with WS <subscript>2</subscript> as the ETL and Spiro-MeOTAD as the HTL having V <subscript>oc</subscript> value of 2.27 V and 1.85 V, J <subscript>sc</subscript> value is 11.35 and 11.44 mA cm <superscript>-2</superscript> , FF is 73.24% and 83.84%, PCE is 18.88% and 17.97%, R <subscript>s</subscript> is 9.94 and 4.88 Ω cm <superscript>2</superscript> and R <subscript>sh</subscript> is 1.35 and 1.14 Ω cm <superscript>2</superscript> respectively. As a result, this research paves the way for future experiments to create entirely inorganic perovskite photovoltaics, free of lead toxicity and exhibit improved photovoltaic ability.<br />Competing Interests: The authors declare that they have no competing interest.<br /> (This journal is © The Royal Society of Chemistry.)
