Theoretical Analysis of Tandem Solar Cell Doped with MASnl3 with P3HT: PCBM Active Layer

The organic materials poly(3-hexylthiophene) (P3HT) and (6,6)-phenyl-C61-butyric acid methyl ester (PCBM) are used as the active layer in the tandem photovoltaic structure. Organic solar cells (OSCs) are thin, affordable to create, and hold significant promise for future OSC technological advancement. A tandem cell model consisting of Glass/ITO/PEDOT: PSS/MASnl3/P3HT: PCBM/Al is employed in this study. The P3HT: PCBM is tuned to 220 nm in AM 1.5D and SUN conditions. The efficiency (PCE) was 27.8% and the fill factor was 75%. Scaps-1D is used to model the PCB structure.
