Manufacture of organic-inorganic composite halide films
The claimed invention relates to the field of material science, i.e. To a method for producing a film made of a crystalline material. The crystalline material film obtained by the claimed method can be used, for example, in optoelectronic devices based on semiconductors, in particular in solar cells. The technical result achieved by using the present invention is to improve the uniformity of the obtained organic-inorganic composite halide film by reducing the number of pores and reducing the surface roughness of the film, which contributes to improving the overall quality of the film as a light absorbing material in a thin film solar cell. The claimed technical result is achieved via an improved method for producing an organic-inorganic composite halide film having a perovskite-like structure, comprising the following stages: (I) forming a layer of reagent B or reagent B'on a carrier substrate; iI) allowing the layer of reagent B or reagent B'to interact with reagent AX and reagent X2; iII) a reaction conversion process providing the applied reagent; therefore, in order to carry out stage II, the membrane obtained in stage I is immersed in a solution of a mixture of reagents AX and X2 in an organic solvent and is held in this solution until the reaction conversion is completed, in order to ensure the correct reaction process B '/B + AX + X2-AnBX (nz + k) + Y', where B represents a metal, B 'represents an oxide or salt of B, AX represents an organic or inorganic halide, X2 represents a molecular halogen, AnBX (nz + k) represents an organic-inorganic composite halide (OICH), Y' is a reaction by-product, z = 1, 2, k = 2, 3, 4, n = 0-4, including 19 claims, 3 tables, 4 figures.
所要求保护的发明涉及材料科学领域，即涉及由结晶材料制成的膜的制造方法。通过所要求保护的方法获得的结晶材料膜可以用于例如基于半导体的光电器件，特别是用于太阳能电池。通过使用本发明实现的技术结果是通过减少小孔的数量和降低膜的表面粗糙度来改进所获得的有机‑无机复合卤化物膜的均匀性，这有助于改进膜作为薄膜太阳能电池中的光吸收材料的整体品质。所要求保护的技术结果经由生产具有类钙钛矿结构的有机‑无机复合卤化物膜的改进的方法来实现，该方法包括以下阶段：(I)在载体基底上形成试剂B或试剂B’的层；II)使试剂B或试剂B’的层与试剂AX和试剂X2相互作用；III)提供所施加的试剂的反应转化过程；因此，为了实施阶段II，将在阶段I获得的膜浸入到试剂AX和试剂X2的混合物在有机溶剂中的溶液中，并且保持在该溶液中直到反应转化完成，以确保正确的反应过程B’/B+AX+X2→AnBX(nz+k)+Y’，其中B代表金属，B’代表B的氧化物或盐，AX代表有机或无机卤化物，X2代表分子卤素，AnBX(nz+k)代表有机‑无机复合卤化物(OICH)，Y’是反应副产物，z＝1、2；k＝2、3、4；n＝0‑4，包括19项权利要求，3个表，4个图。
