Description

technical field [0001] The invention belongs to the technical field of preparation of perovskite photoelectric components, and particularly relates to a novel perovskite photoelectric component and a preparation method thereof. Background technique [0002] Perovskites are a class of compounds with the structural formula ABX 3 The general term for crystal materials. In the organic halide perovskite structure, A is usually a cation such as methylammonium (MA) and formamidine (FA), B is a metal cation such as lead and tin, and X is an anion such as chlorine, bromine, and iodine. Perovskites have excellent semiconductor properties and have made remarkable progress in the field of photovoltaic devices. [0003] In the process of manufacturing large-area optoelectronic devices in industry, the active material is usually isolated into several individual small parts, and then connected in series, thereby improving the performance of the entire active region. For perovskite mater...

Problems solved by technology

However, the dispensing method used in this method to coat the isolation layer has many defects in practical applications. For example, the dispensing operation has a long exposure time in the air, and the perovskite is severely eroded by water and oxygen; The spacer is large, which reduces the area of ​​the photoactive area; the high-energy ultraviolet light used in glue curing will cause the degradation of perovskite; after the glue is cured, there will be volume expansion or contraction, which will affect the protection effect on the side of the perovskite
