Abstract


The effect of band offsets in CH3NH3PbI3-xClx perovskite solar cell has been investigated using SCAPS one-dimensional device simulator. In the thin-film compound solar cells, the band offset between buffer/absorber layers are the decisive factor for carrier recombination at the interface, determining open-circuit voltage (Voc). During this study, the impact of two kinds of band offsets, i.e., the conduction band offset of absorber/buffer layers and the valence band offset of absorber/hole transport material (HTM) have been investigated. The calculated efficiency shows a good increment in efficiency as compared to the previous reported result.
