AbstractHybrid two-dimensional (2D) halide perovskites has been widely studied due to its potential application for high performance perovskite solar cells. Understanding the relationship between microstructural and opto-electronic properties is very important for fabricating high-performance 2D perovskite solar cell. In this work, the effect of solvent annealing on grain growth was investigated to enhance the efficiency of photovoltaic devices with 2D perovskite films based on (BA)2(MA)3Pb4I13 prepared by single-source thermal evaporation. Results show that solvent annealing with the introduction of solvent vapor can effectively enhance the crystallization of the (BA)2(MA)3Pb4I13 thin films and produce denser, larger-crystal grains. The thin films also display a favorable band gap of 1.896 eV, which benefits for increasing the charge-diffusion lengths. The solvent-annealed (BA)2(MA)3Pb4I13 thin-film solar cell prepared by single-source thermal evaporation shows an efficiency range of 2.54–4.67%. Thus, the proposed method can be used to prepare efficient large-area 2D perovskite solar cells.

Abstract All inorganic lead-free halide perovskites have attracted much attention due to their non-toxic and good band gap. In this paper, we first prepared all inorganic lead-free perovskite CsBi3I10 thin films by single source thermal evaporation deposition. The results show that CsBi3I10 thin films prepared by single source thermal evaporation have layered structure, high purity hexagonal phase and high crystallinity, which are consistent with the theoretical calculation results. The surface of the thin film was compact and uniform, and had high homology with the crystal structure of the evaporation source material. After annealing, the crystallinity of the film was further improved. The band gap of the CsBi3I10 thin film calculated was 1.83 eV, Perovskite solar cells based on CsBi3I10 thin films exhibit an efficiency of up to 0.84%. These results indicate that the proposed single source thermal evaporation method has the potential to prepare high efficiency inorganic lead-free perovskite solar cells.
