By passivating the defects of a perovskite film with two dimensional ZnIn2S4 nanosheets, non-radiation recombination at interfaces was suppressed and contact with water vapor was avoided, leading to a high efficiency of 20.55%.
The defects of a perovskite film were first passivated by two dimensional ZnIn2S4 nanosheets, the non-radiation recombination at interfaces was suppressed and the contact of the perovskite film with water vapour in the air was avoided, resulting in a high efficiency of 20.55%.
