Synergistic Benzohydrazide (BH) and Zinc Bromide (ZnBr2) Doping for α-CsPbI3 Perovskite Films and Photodetectors via One-Step Co-evaporation
All-inorganic CsPbI3 perovskite is a promising optoelectronic material; however, its device performance is impeded by phase instability and defect-mediated nonradiative recombination. Here, we present a synergistic co-doping strategy employing benzohydrazide (BH) and zinc bromide (ZnBr2) to concurrently address these...
