摘要：

We have synthesized cobalt-doped NiOx nanoparticles containing 0.5, 1, 2, 5 and 10 mol% cobalt ions and have investigated their electronic properties, which can be processed into smooth and pinhole-free layers at low temperature (< 150 degrees C) as hole transport layers (HTLs) for perovskite solar cells (PSCs). We have revealed that the relationship between conductivity of HTLs and hole extraction properties to improve the photovoltaic performance. The thin film of cobalt-doped NiOx nanoparticles showed higher conductivities compared to pristine NiOx nanoparticles. Consequently, PSCs with power conversion efficiencies over 14.5%, an improvement from 11.5% for those with the pristine NiOx-based HTL, have been obtained. This work will contribute to the development of doped metal oxide HTLs, which are processable at low temperature.
