Dual interfacial engineering for efficient Cs2AgBiBr6 based solar cells

Journal of Energy Chemistry, 2021
Abstract The emerging lead-free halide double perovskite solar cells have attracted widespread attentions due to their long-term stability and non-toxicity, but suffer from the low device performance. One efficiency-limiting factor is the improper contacts between the halide double perovskite and anode/cathode electrodes.
