Abstract

The invention discloses a method for manufacturing a polycrystal perovskite thin film and a solar cell device. The method includes the steps that a mixed aqueous solution of polymer and salt is subject to wet process film formation on a substrate; and a film acts with metal halide steam mutually to be then subject to heat treatment, and the flat and compact polycrystal perovskite thin film is obtained. By means of the method, the flat and compact polycrystal perovskite thin film can be manufactured, the process is simple, crystallization is rapid, stability and the repetitive rate are high, harms to the environment are avoided, the degree of dependency to the environment is low, and the cost is low.

Description

technical field

[0001] The invention belongs to the technical field of organic-inorganic composite solar cells, and relates to a polycrystalline perovskite film, in particular to a method for preparing a polycrystalline perovskite film and a solar cell device. Background technique

[0002] In 2013, perovskite solar cells were selected as one of the top ten scientific breakthroughs by the American "Science" magazine. Perovskite, a new type of organic-inorganic composite material, quickly occupied an overwhelming advantage in the field of photovoltaics due to a series of advantages. .

[0003] The emergence of organic-inorganic composite perovskite materials can be traced back a century ago, but at the time it was believed that such materials had not been studied much due to the toxicity of lead in them. When in 2009, Japan Miyasaka used perovskite materials (CH 3 NH 3 PB 3 and CH 3 NH 3 PbBr 3 ) As a dye, the power conversion efficiency (PCE) of 3.8% was obtained for t...
