Problems solved by technology

[0005] At present, there is rarely a method that can fully and uniformly prepare carbon nanotubes and titanium dioxide into a composite slurry. The titanium dioxide slurry compounded with carbon nanotubes overcomes the conductivity and poor mechanical properties of electrodes prepared with a single component of titanium dioxide. Disadvantages, expand the application range of titanium dioxide to improve the field of emerging energy materials

Description

technical field [0001] The invention relates to photoelectric cell electrode materials, in particular to a preparation method of dye-sensitized solar cell slurry. Background technique [0002] With the development of industry and the increase of human activities, human consumption of energy is increasing day by day, while underground non-renewable mineral energy is becoming increasingly scarce, and the contradiction between energy supply and demand is increasingly intensified. Energy issues have become one of the key issues affecting human survival and development. . Not only that, but the greenhouse gases produced by the burning of fossil energy accelerate the pace of global warming and cause various natural disasters to occur frequently. Therefore, the development and utilization of new, environmentally friendly and renewable energy sources is an urgent task. Solar cells can directly convert light energy into electrical energy, which is a way to effectively utilize solar ...
