Abstract

A conjugated fluorene polymer is provided, which is defined by structure formula (1), wherein: R 1 , R 2 , R 3 , R 4 represent H or C 1 -C 20 alkyl, x+y=1, x‰ 0, y‰ 0, n is a natural number between 1-1000, Ar 1 is a group containing thiophene. A preparation method for the conjugated fluorene polymer and a solar cell device containing the conjugated fluorene polymer are also provided. Due to fluorene or its derivatives and conjugated structure, the conjugated fluorene polymer exhibits an excellent light stability and thermal stability. In addition, since thiophene and benzothiadiazole groups are introduced into the main chain of the polymer, the spectral response range of the polymer is broadened.

Description

technical field [0001] The invention belongs to the technical field of organic materials, and in particular relates to a fluorene-containing conjugated polymer, a preparation method thereof and a solar battery device. Background technique [0002] Today's world economy is mainly based on fossil energy, such as coal, oil and natural gas. However, these non-renewable fossil energy sources are constantly being exhausted. Since the beginning of the 21st century, global energy issues and the ensuing environmental pollution and climate warming have become increasingly prominent and gradually intensified. Solar energy is considered to be one of the most promising renewable energy sources because of its widespread and vast distribution, large amount of resources, no pollution, cleanliness, safety, and easy access. [0003] In order to make full use of the energy irradiated by sunlight, people continue to develop new materials that can absorb sunlight. Among them, inorganic semicon...
