Enhanced Electron Transport in Heterojunction Sn-Perovskite Solar Cells Assisted by [6,6]-Phenyl-C61-butyric Acid Methyl Ester as a Dopant

Tin halide perovskite (THP) possesses p-type semiconducting properties owing to innate Sn oxidative defect states. These defect states create imbalance in charge collection at the interfaces, which hinders overall solar cell efficiency. To …
