dc.description.abstract | Organic–inorganic hybrid perovskite solar cells (PSCs) have shown advantages of high efficiency, solution production, and flexibility, and have become a potential candidate for next-generation photovoltaic technologies. For PSCs in p–i–n configuration, inorganic p-type semiconductors are competitive as hole transport layers (HTLs) due to their low-cost, chemical stability, high transparency, and solution processability. Herein, solution-processed, ternary metal oxide NiCrO3 films were reported as HTLs in PSCs. Compared with the most prevalent NiOx HTLs, the uniform and pin-hole free NiCrO3 HTLs delivered higher electrical conductivity and a deeper valence band, enabling improved hole transport and interfacial band alignment. The NiCrO3 HTLs also present accelerated charge extraction and slow charge recombination as observed by transient spectroscopy studies. A high power conversion efficiency (PCE) of 19.93% was achieved, which is much higher than that of a NiOx based device (18.35%). This work demonstrated the potential of NiCrO3 as an effective HTL in PSCs, and may promote the development of ternary metal oxides as new building blocks for high performance PSCs. | |
