Abstract

We synthesized two types of MAPbI₃single-crystal films with dominant (001) and (100) surface orientations for solar cells. We found that both MAPbI₃(001) and (100) single-crystal films have efficient hole transfer into poly(triaryl)amine (PTAA), as evident from the reduced photoluminescence (PL) intensity and lifetime, as well as the type-II energy alignment. Unlike a MAPbI₃(100) single-crystal film with a strong PL quenching due to efficient electron transfer to phenyl-C₆₁-butyric acid methyl ester (PCBM), the MAPbI₃(001) single-crystal film exhibits an increase in PL intensity in the presence of PCBM, which can be attributed to surface passivation. Interestingly, different from the conventional MAPbI₃(100) that suffers from a significant decrease in the PCE (from 19.3 to 14.4%), the MAPbI₃(001) single-crystal film shows an increase in the PCE (from 16.0 to 17.2%)
