Abstract

Hybrid organic-inorganic perovskite solar cells have attracted lots of attention in recent years. Growth and properties of perovskite layer and its relationship to photovoltaic performance have been extensively studied. Comparably less attention was devoted to the research of the influence of electron transporting layer (ETL). Conventionally, TiO₂ is selected as ETL. However, photocatalytic property of this transparent conductive metal oxide reduces the stability of perovskite solar cells under illumination. To realize the commercialization, the stability of perovskite solar cell must be improved. In this study, we replace TiO₂ by In₂O₃, which is not only transparent and conductive, but also has little photocatalytic effect and it has higher electron mobility than TiO₂. Investigation on different solution process methods of In₂O₃ as ETL is demonstrated.
