Abstract

Organic-inorganic perovskite solar cells have attracted great attention because of low processing cost and high photovoltaic performance over the last few years. This work shows the effect of the density of deep defect states at the mesoporous TiO2 interface on the photovoltaic characteristics of perovskite solar cell. Charge transport for perovskite solar cells is modeled based on the physics of charge emission, charge capture, and recombination processes assisted by deep interfacial trap states at perovskite / mesoporous TiO2 interface. This model suggests that back recombination process of holes and electrons at the perovskite / mesoporous TiO2 interface occurs due to trapping of conduction band electrons and valence band holes by deep trap states. The developed model further studied the impact of interface states on the photovoltaic performance of perovskite solar cells.
