Ozone-Treated Aluminum Doped Zinc Oxide for ETL-Free Stable Perovskite Solar Cells
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.

Perovskite Grain Size Modulation by annealing in Methyl-Amine Environment
Here we present a novel vapor-annealing technique to improve morphology of pure-iodide perovskite (CH 3 NH 3 PbI 3 ) thin-films and get pin-hole-free coverage with > 10μm grain size. X-Ray diffraction (XRD) measurement confirms that the annealed films are phase pure perovskite. The larger grain size leads to a significant increase in the effective recombination lifetime of charge carriers, with the best films showing lifetime of >50 μs. Solar cells fabricated with the large grain perovskite thin film shows significant improvement in short-circuit current density (J sc ) and open-circuit voltage (V oc ).
