Mapping the photocurrent and photovoltage of hybrid perovskite thin films under concentrated sunlight
In this work, we study spatially resolved generation of photocurrent and photovoltage of mesoporous PbI2 scaffolds CH3NH3PbI3 perovskite film with and without polyaniline (PANI) to reveal the microscopic effects of material degradation under concentrated sunlight. The degradation in absorption of CH3NH3PbI3 film after exposure to concentrated sunlight is mainly due to the decomposition of perovskite, and no degradation was observed for PANI-CH3NH3PbI3 film. Direct measurement of photocurrent and photovoltage have been investigated for PbI2 scaffold perovskite films at the nanoscale. These results reveal substantial variation in the photocurrent and photovoltage that correlated with the microstructural features of the perovskite film with degradation under concentrated sunlight.
