Enhanced Charged Transport in Al-Doped ZnO Nanotubes Designed Via AlCl3 Doping and Synchronous Etching of H2O-Oxidized ZnO Nanorods for Perovskite Solar Cells

Christian Mark Pelicano and Hisao Yanagi

I would like to thank my thesis adviser, Prof. Hisao Yanagi for his unending support and guidance as well as for giving me an opportunity to work on this topic. I would also like to express my gratitude to NAIST for the experimental and financial assistance in attending this conference.

Highly efficient PSCs usually employ an electron-transporting layer (ETL) such as TiO2, SnO2 and ZnO. Among these metal oxides, ZnO is particularly promising owing to its high electron mobility and low temperature processability. Control over charge carrier transport is also of key importance to realize highly efficient PSCs and low content doping of metal oxides has been considered as a way of improving this property of ETLs. In our previous work, we presented a novel route of designing various nanostructured ZnO films via a strategic low-temperature H2O oxidation and their application as ETL for PSCs. This presentation demonstrated a novel approach to generate Al-doped ZnO nanotubes (AZO NTs) via one-step AlCl3 etching and doping of H2O-oxidized ZnO nanorods (NRs). Our results not only demonstrate the promising potential of AZO NTs for photovoltaic applications, but also offer significant insights into their design and utilization for next-generation optoelectronic devices.
