Abstract

The invention discloses a phenothiazine-containing polymerization metal complex as well as a preparation method and an application thereof. The phenothiazine-containing polymerization metal complex is a novel dyestuff with a phenothiazine-thiophene side chain type D-pi-A structure. Compared with a conventional precious metal dyestuff, the novel dyestuff has the advantages of low cost, simple preparation, relatively high yield and good thermal stability and can be applied to dye-sensitized solar cells.

Description

technical field [0001] The invention belongs to the field of functional polymer materials and relates to the technical field of high dye-sensitized solar cells. [0002] In particular, phenothiazine-thiophene cascaded polymer dyes and methods for their preparation. Background technique [0003] The energy issue is the focus of world competition in the new century, and it will become the primary cause of world conflicts. Traditional fossil energy is facing problems such as resource depletion and serious environmental pollution, which is not conducive to improving people's livelihood and improving people's living standards. Therefore, the development of pollution-free clean and renewable energy is an important measure to solve energy crisis and environmental problems. [0004] Dye-sensitized solar cells are an important part of renewable energy utilization. Since the advent of cells with a photoelectric conversion efficiency greater than 7% in 1991, scientists have set off a...
