Abstract

Metal oxide-based electron transport layer (ETL) is one of the vital components in conventional n-i-p type perovskite solar cells (PSC) that enables efficient electron extraction and transport within the device. Nonetheless, native point defect associated with oxygen vacancies that naturally exist in the ETL materials such as TiO2, SnO2 and Nb2O5 could deteriorate the overall performance of the PSC. In this chapter, the intentional and unintentional formation of oxygen vacancies during the fabrication process of the ETL will be firstly clarified. The properties of oxygen vacancies in the viewpoint of structural, optical and electrical as well as surface wettability will also be profoundly elaborated to provide valuable insight on the impact of oxygen vacancies in the ETL towards efficiency, hysteresis and stability of PSC devices.
