Abstract

A first aspect of the embodiments of the invention provides a transparent electrode. The transparent electrode comprises a substrate and a transparent conductive film arranged on the surface of the substrate. The materials of the transparent conductive film include a graphene material and a conductive polymer of which the chemical structural formula is shown in formula (I), the graphene material includes graphene or doped graphene, and the graphene material is evenly dispersed in the transparent conductive film. As the side chain of the conductive polymer contains no long alkyl chain, the oil solubility is low, and the conductive polymer is less susceptible to corrosion of oil-soluble solvents in the subsequent application. Therefore, the stability of the transparent electrode is improved, and the problem in the prior art that the conductive macromolecule layer of the graphene conductive macromolecule composite transparent electrode fails as the conductive macromolecule layer is susceptible to corrosion of oil-soluble solvents is solved. The embodiments of the invention further provide a preparation method of the transparent electrode and an organic solar cell containing the transparent electrode.

Description

technical field [0001] The invention relates to the technical field of electrodes, in particular to a transparent electrode, a preparation method thereof, and an organic solar cell. Background technique [0002] At present, the most commonly used transparent electrode materials are metal oxides or fluorides based on traditional inorganic materials, such as ITO, IZO or FTO, etc. However, with the increasing scarcity of rare metals, increasing prices, and poor thermal stability of transparent conductive films, Poor flexibility and complex preparation process limit their application in the field of optoelectronic functional devices. Therefore, the development of electrode materials with abundant raw materials, low price, good flexibility, transparency and high conductivity is of great significance to the development of optoelectronic functional devices and other fields. [0003] Due to its high mobility, excellent mechanical properties, good light transmission and thermal stab...
