چکیده
Compositional grading of the MAPb1-ySnyI3 absorber layers via controlled variation of the Pb/Sn ratio provides a pathway to enhance band alignment, and mitigate recombination in perovskite solar cells (PSCs). In this study, an optimized grading model for the MAPb1-ySnyI3 PSC is designed and simulated using SCAPS. Compounds with higher bandgap energies (Eg) are employed near the absorber/electron transporting layer (ABS/ETL), and hole transporting layer/absorber (HTL/ABS) interfaces to control the recombination rate. To enhance carrier generation, lower Eg materials are incorporated at the central regions of the absorber layer. By exploring y = 0, 0.5, and 1 as the grading end materials, the best model with power conversion efficiency (PCE) of 28.86% is achieved using 0.5<y<1, and optimized grading depth of the absorber layer. This model improves the PCE of MAPbI3 and MASnI3 devices by around 22.7%, and 31.4%, respectively. Finally, a parabolic grading is employed to simulate the experimental transition of Eg between 1.18 eV and 1.3 eV.
