Description

Technical field [0001] The invention relates to the field of Perovskite Solar Cells, in particular to a method for preparing the perovskite solar cell. Background technique [0002] Organic-inorganic hybrid perovskite materials have been introduced into organic solar cells by scientists due to their high carrier mobility, long diffusion length, adjustable optical band gap, and bipolar transmission, effectively improving this type of solar energy The efficiency of the battery. Through various optimizations, the current international efficiency of thin film solar cells based on such materials has reached 19.3% (H. Zhou, Q. Chen, et al. Interface engineering of highly efficient perovskite solar cells. Science, 345, 6196, 542- 546, 2014.), has a very broad application prospects. [0003] The production process of traditional organic-inorganic hybrid perovskite solar cells is generally to deposit n or p-type conductive layer on conductive glass by spin coating, and then deposit CH on ...
