Description

technical field [0001] The invention relates to the technical field of solar cell materials, in particular to triarylamine compounds, their preparation methods, and their application in the preparation of solar cells. Background technique [0002] In order to slow down climate change and solve the world's energy crisis, it is a global demand to find a suitable energy source to replace fossil fuels. Solar energy is an inexhaustible and non-polluting energy source, which is usually converted into electrical energy for use, so the development of solar cells has received considerable attention. In the past decade, dye-sensitized solar cells (DSSCs) have been considered as a better alternative to traditional expensive and inefficient silicon-based solar cells due to their ease of fabrication, high efficiency, and low cost. [0003] Dye sensitizer is the main factor affecting the photoelectric conversion efficiency of DSSC. The research on dye sensitizers at home and abroad is m...
