Abstract

The all-inorganic CsPbBr3 perovskite solar cell without electron-hole transport layer has attracted widespread attention from researchers due to its simplified process, reduced costs and excellent air stability. However, its photoelectric conversion efficiency is currently relatively low. Here, the CsPbBr3 perovskite thin film with doping MgBr2 is used as a novel absorber for all-inorganic carbon-based perovskite solar cell. There is no significant change in the optical band gap of CsPbBr3 after the incorporation of MgBr2. However, doping MgBr2 can effectively enhance the crystallinity of CsPbBr3 thin film and improve carrier separation capability of CsPbBr3 perovskite cell. Compared with the CsPbBr3 perovskite cell without doping MgBr2, the efficiency of the CsPbBr3 perovskite cell with doping MgBr2 increases from 1.79% to 2.30%. This work provides a novel pathway for preparing highly-efficient CsPbBr3 perovskite solar cell..
