Mathematical Modelling And Simulation of CH3NH3Pb(I1-Xbrx)3 Based Perovskite Solar Cells For High Efficiency

Abstract

Mathematical modelling can offer the physical intuitions about the charge transport process inside a solar cells and provide the various elements affecting their performance. In the present paper, (CH3NH3Pb(I1-xBrx)3 based various perovskite solar cells have been mathematically simulated deploying SCAPS simulator. Various Hole Transport layers (HTLs) based on thickness, total defect density and donor density of mixed halide perovskite have been compared using Cd1-xZnxS as an Electron Transport Layer (ETL). Amongst the proffered HTLs, P3HT [Poly(3-hexylthiophene)] executed better and exhibited the PCE of 28.28%. During the simulation, mixed halide perovskite layer with thickness of 700 nm has been found suitable for the effective solar cell design. These mathematically simulated outcomes indicate the optimum efficiency of the solar cell that may further be prompted to design the extremely high efficient solar cells.

“…This is not a good situation for a solar cell. Furthermore, the thicker perovskite layer promotes greater recombination by establishing a crucial channel for charge carrier transport [31,32]. The Gold (Au) is incorporated as front contact with work function 5.47.…”

Impact of absorber layer thickness and defect density on the performance of MAPbI3 solar cells based on CuO2 as hole transport material

“…PSCs have shown a lot of promise as a potential nextgeneration technology for solar cells that will replace ordinary silicon solar cells. Scientists and researchers are working to develop PSC's mechanisms, functions of each layer, and overall performance characteristics to replace traditional silicon solar cells with PSC as the most competitive competitor for the next generation of solar cells by achieving the maximum efficiency level possible [13]. Problems with stability and toxicity of standard MAP b I 3 perovskite leads to the invention of hybrid perovskite (MA1 x FA x P b 1 y Sr y I 3 ) to lessen these effects after conducting a numerical simulation analysis using the SCAPS-1D software.…”
