Abstract

The invention belongs to the field of photovoltaic cells, and specifically discloses a flexible perovskite photovoltaic cell film that can be pasted and a preparation method thereof. The glue solution prepared by mixing the precursor containing lead, tin or cadmium, silica sol, and flake molybdenum disulfide is scraped and coated on the flexible substrate, and then placed in a high-pressure chamber with a mixed gas of hydrogen halide and organic amine. On the flexible substrate, the crystallized sheet-like molybdenum disulfide is used as the template to gradually grow into a uniform and dense perovskite film, and then taken out and dried to obtain a stickable flexible perovskite photovoltaic cell attached to the flexible substrate. film. In this method, a dense perovskite film is grown by using crystallized molybdenum disulfide as a template, and colloidal silica is added to the system. The prepared perovskite film has good compactness, few defects, and certain flexibility. , easy to use, and at the same time provide technical support for industrial production of perovskite photovoltaic cells on a large scale.

Description

technical field [0001] The invention belongs to the field of photovoltaic cells, in particular to the preparation of photovoltaic cell films, in particular to a flexible perovskite photovoltaic cell film that can be pasted and a preparation method. Background technique [0002] With the rapid growth of the world's energy demand, the increasingly serious environmental problems have become a bottleneck hindering social and economic development, and the establishment of clean and sustainable new energy has become a global consensus. With the rapid development of new energy in recent years, clean and sustainable new energy is the ultimate in energy development. Solar energy has developed rapidly as an inexhaustible clean energy. Solar cells convert solar energy directly into electricity, which is one of the best ways to use solar energy effectively. [0003] The development of solar cell technology has roughly gone through three stages: the first generation of silicon-based so...
