Problems solved by technology

Another method is to introduce 0.1%-2% initiator with crosslinking agent components into the active layer, but this method will introduce some defect states in the actual operation process, because the chemical reaction of the initiator is a decomposition reaction, The mechanism of action is that the decomposed free radicals promote the chemical polymerization of the donor material or the acceptor material, thereby improving the stability, which will lead to the weakening of the electron extraction ability of the material, resulting in a lower fill factor

Abstract

The invention relates to an organic solar cell structure based on a dimethyl acrylate monomer, and a preparation method for an organic solar cell structure. The structure sequentially comprises a transparent conductive substrate, an electronic transmission layer, an organic active layer, a hole transmission layer and a metal electrode from the bottom to the top. The organic active layer comprisesa P3HT: PCBM and a dimethyl acrylate monomer. The dimethyl acrylate monomer is added to the organic active layer. An insoluble insulating network skeleton is formed through ultraviolet treatment, thereby solving a problem that the organic active layer is not stable in shape, and enabling the organic active layer to be good in thermal stability. Moreover, the structure improves the mechanical performances of a film, and provides technical help for the flexible printing.
