SOLUTION-PROCESSIBLE ORGANIC-INORGANIC PLANAR HETEROJUNCTION SOLAR CELL AND PREPARATION METHOD THEREFOR

摘要

A solution-processible organic-inorganic planar heterojunction solar cell and a preparation method therefor through solution processing. The solar cell comprises a substrate, an anode, an anode interface layer, a photoactivity layer, a cathode interface layer, and a cathode that are sequentially stacked. The material of the photoactivity layer is an inorganic material that is soluble in a solvent and is of a perovskite structure, and performance of the material can be improved by adding polymer additives. The photoactivity layer is made of the solution-processible perovskite organic-inorganic hybrid material, and the anode interface layer and the cathode interface layer are processed through organic material solutions. By means of the method, the problem that energy consumption is high in cell device processing is effectively solved, large-scale production is achieved, and high efficiency is achieved; and the defects in the prior art that the inorganic material needs to be processed at high temperature and the cost of the materials in the organic solar cell is high are overcome. The material and the method can be applied, as a novel material and method, to solar cells.
