Abstract

The invention relates to a method for synthesizing ruthenium tris(bipyridine) complex. The method comprises the following steps: suspending a ruthenium tris(bipyridine) complex dye precursor into a solvent; adding a quaternary ammonium salt when agitating; adjusting the pH value to 7-14, preferably 10-14; agitating until the ruthenium tris(bipyridine) complex dye precursor is completely dissolved; gradually dropwise adding an acid liquor to acidify until obvious solid sediments appear; orderly freezing, filtering and drying to obtain the ruthenium tris(bipyridine) complex solid.

Description

technical field [0001] The invention relates to a synthesis method of a bipyridyl ruthenium complex, and the bipyridyl ruthenium complex can be used as a photosensitive material of a dye-sensitized solar cell. Compared with similar dyes, the bipyridyl ruthenium complex compound synthesized in the present invention has better solubility, can reduce the solvent needed for the dye solution in the battery device manufacturing process, increase the concentration of the dye solution, and shorten the working time of the solar cell. The electrode manufacturing process simplifies the process and reduces the cost. Background technique [0002] As one of the renewable energy sources, solar energy has many advantages, such as inexhaustible, inexhaustible, safe and reliable, non-polluting, and not restricted by geographical environment, and has received more and more attention. However, the processing technology of traditional silicon solar cells is very complicated, the material requir...
