An alternate use of PEAI for enhancing the performance of inverted perovskite solar cells is demonstrated, by employing it as an anti-solvent during the perovskite fabrication process. The results show an enhancement of the open-circuit voltage as compared to the PEAI post treatment.

We show that trapped electrons recombine with free holes unexpectedly slowly, on microsecond time scales, relaxing the limit on obtainable open circuit voltage.
