Abstract

The embodiment of the invention provides a preparation method of a perovskite solar cell. The method comprises the steps of depositing a p-type organic conductive layer on indium tin oxide (ITO) conductive glass; depositing a CH3NH3PbI3 layer with an organic-inorganic hybrid perovskite structure on the p-type organic conductive layer by adopting an ultrasonic spraying method; depositing an n-type organic conductive layer on the CH3NH3PbI3 layer; and depositing a metal electrode layer on the n-type organic conductive layer. The technical scheme provided by the invention has the beneficial effects that preparation is carried out by using the ultrasonic spraying method, the utilization rate of raw materials can be improved, the production cost is reduced, and large-scale production is realized.

Description

technical field [0001] The invention relates to the field of perovskite solar cells (Perovskite Solar Cells), in particular to a preparation method of perovskite solar cells. 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, which effectively improves the performance of this type of solar energy. The efficiency of the battery. Through various optimizations, the efficiency of thin-film solar cells based on such materials in the world has reached 19.3% (H. Zhou, Q. Chen, et al. Interface engineering of highly efficient perovskites solar cells. Science, 345, 6196, 542-546, 2014.), with Very broad application prospects. [0003] The traditional manufacturing process of organic-inorganic hybrid perovskite solar cells is generally to deposit an n or p-type conductive layer on the co...
