Abstract:
Perovskite solar cells (PSCs) have emerged as one of the most promising Photovoltaics Technologies in recent years. Methyl Ammonium Lead Tri-Iodide (MAPbI3) based PSCs gained attention because of their impressive Power Conversion efficiencies (PCE). However, the presence of thermally unstable Methyl Ammonium (MA) Cation and toxicity of lead (Pb) limits its progress towards future commercialization. FA (Formamidinium) and Sn (Tin) have emerged as good alternatives for MA and Pb. FASnI3 has been found to be more thermally stable and nontoxic but lower in PCE than MAPbI3. In this work, FASnI3 is numerically modeled in SCAPS-1D software. To enhance the performance of FA-PSC, copper and carbon charge transport layers are used. To improve electric conduction CuI is used as HTL (Hole Transport Layer) while to improve thermal conduction PCBM (phenyl-C61-butyric acid methyl ester) is used as ETL (electron Transport Layer). For further performance improvement, the optimized thickness for each active layer (Absorber, PCBM, and CuI) is identified and the effect of thickness on parameters like Voc, Jsc, FF, and PCE is observed. Thickness optimization showed phenomenal results in terms of an increase in PCE from 17.37% to 20.5 %. Moreover, the effect of the charge transport layer (CuI and PCBM) on the absorption bandgap alignment electric field intensity are also been analyzed and studied in detail in this paper
