The serious consumption of fossil fuels has led to many environmental problems. People have begun to seek a non-polluting new energy source to replace fossil fuels to solve the problem of energy shortage. The use of solar energy to generate electricity has become an abstract way to solve environmental pollution and energy crisis. In this paper, taking bismuth-based perovskite(BBP) as an example, a new type of solar cell prepared by using CsBi3I10 perovskite thin film avoids the toxicity of lead perovskite solar cells and is safer and more environmentally friendly. In this paper, the effect of anti-solvent and temperature on the solar performance of CsBi3I10 perovskite was investigated. It was found that when the anti-solvent low price time was 10 s, the performance parameters of solar cell devices were the largest. Increase to a certain extent, the absorption intensity will become slower.
