Perovskite CH3NH3SnI3 Solar Cell Performance Investigation with SnS2 Buffer Layer

A Solar cell, also identified as a photovoltaic cell, is a digital device that converts daylight directly into electric electricity through the photovoltaic effect. The research community is paying close attention to perovskite solar cells (PSCs) because to the sudden increase in their efficiency (PCE) to 25.6% over a short period of time. However, a significant barrier to their commercialization has been the poisonousness of the more prevalent lead created perovskites. Due to their high efficiency in converting power and cheap manufacturing costs, perovskite materials have attracted a lot of attention recently. Perovskite cells are retaining a very high desire within the solar energy world, with a year-over-year increase in efficiency. In this study, the TCO/SnS2/CH3NH3SnI3/p-CH3NH3SnI3 solar cell was simulated using SCAPS-1D. For this, each of these nonidealities was carefully examined. The synthetic solar cell is enhanced by changing the buffer layer and expanding the absorber layer. Based on the suggested device architecture, the effect of back-contact metal work function (BMWF), operating temperature, SnS2 ETL, p-CH3NH3SnI3 HTL, absorber layer carrier concentration is investigated to enhance cell performance. The impact of each of these layers was gradually examined. The solar cell's efficiency was measured at 600 nm thickness of absorber layer then Power conversion efficiency is 30.22%, fill factor of 83.72%, VOC of 1.04 V, and JSC of 34.50 mA/cm2.
