Abstract

The invention belongs to the technical field of solar cells, and specifically relates to an X-type double-anchored dye sensitizer and its preparation method and application. The molecular structure of the dye sensitizer is shown in formula A. The morphine structure is used as the matrix, and the electron donor end is modified with alkylbenzene containing a long carbon chain. The purpose is to inhibit the electron recombination and increase the solubility of the dye molecule. The X-type dye molecule is constructed with bisbenzoic acid as the anchor group to improve the stability of dye adsorption. properties, while increasing the adsorption capacity of dye molecules. The dye can be synthesized by simple suzuki coupling, condensation, bromination, hydrolysis and other conventional reactions, and the prepared dye molecule has good photoelectric conversion performance when used in solar cells, which has great significance for the design of new dye sensitizers Good instructive sense.

Description

technical field

[0001] The invention belongs to the technical field of solar cells, and in particular relates to an X-type double-anchored dye sensitizer and its preparation method and application. Background technique

[0002] The development of the times and the advancement of science and technology have brought convenience to people's lives, but they have also caused serious environmental pollution and energy crises. At present, how to effectively develop new energy to replace traditional fossil energy is the world's One of the main problems facing countries. New energy sources include wind energy, water energy, tidal energy, geothermal energy, nuclear energy and solar energy, etc. Among them, solar energy has many advantages such as extremely abundant reserves, convenient collection, clean and pollution-free, etc. The development and utilization of solar energy has always been the research of scientists hotspot. Photovoltaic power generation is currently one of the mai...
