Abstract

Aluminum doped zinc oxide (AZO) can function as effective electronic transport layer (ETL) cum transparent electrode for perovskite solar cells. Measured electronic band diagram shows that AZO/perovskite is a carrier-selective interface that blocks holes but allows transport of electrons. The performance of AZO/perovskite interface is significantly improved by exposing AZO surface to ozone. Ozone depletes carriers from top few nanometers of AZO, forming AZO/un-doped-AZO/perovskite interface with lower recombination losses, resulting in champion cell efficiency of 10.5% and open circuit voltage (Voc) up to 1.05V. AZO interface is also stable. Devices retained 90% of initial Voc even after 60 days of ambient storage.
