英文摘要	Planar hybrid perovskite solar cells (PSCs) attract great attention due to their obvious advantages of low-temperature processing with a high power conversion efficiency (PCE) up to 23.32%. Here, Co-doped TiO2 (Co-TiO2) deposited by a straightforward low-temperature chemical bath deposition (CBD) method is explored. Using Co-TiO2 as an electron transport layer (ETL) for the planar PSCs, the effects of doping on TiO2 morphology, electronic properties, and solar cell performance are investigated. The PCE increases to 19.10% when the Co doping concentration is optimized at 5 mol%, an increase of 17.40% compared with that using the pristine TiO2. Meanwhile, the notorious J-V hysteresis is suppressed to a greater extent. Considering that the low-temperature CBD is comparable with continuous roll-to-roll processing, it makes the process and the Co-TiO2 ETL potential candidates for low-cost commercialization.
