NUMERICAL SIMULATION OF AN ENVIRONMENTAL FRIENDLY PEROVSKITE (CH3NH3SnBr3) BASED SOLAR CELL

Abstract

The stability and toxicity issues, lead (Pb)-based perovskite solar cells face significant limitations. Under such circumstances, the development of efficient perovskite solar cells (PSC) may depend heavily on tin (Sn)-based organic-inorganic perovskite solar cells. An environmentally friendly, stable, and lead (Pb) free CH₃NH₃SnBr₃-based organic-inorganic n-i-p-shaped perovskite solar cell (PSC) with the use of all inorganic charge transport elements for optimal reliability is suggested here by a theoretical investigation(1). By examining elements such as charge transport materials and their interface defect density, absorber defect density, ETL, HTL, and absorber thickness, a high-rise performance PSC is attained at room temperature. According to the data obtained, CH₃NH₃SnBr₃ has the potential to be a significant absorbing perovskite in perovskite solar cell technology(2).
