Description
technical field [0001] The invention relates to the technical field of solar cells, in particular to a method and device for predicting the performance of dye-sensitized solar cells. Background technique [0002] Solar energy is a renewable energy source, and developing solar cells to convert solar energy into electrical energy through photoelectric conversion technology is one of the most effective ways to utilize solar energy. Dye-sensitized solar cells (Dye Sensitized Solar Cell, DSSC) have good application prospects in the fields of industrial production and scientific research due to the advantages of abundant raw materials, low production cost, simple preparation process, mass production and environmental friendliness. Greater market advantage. [0003] Since the performance of DSSC determines the cost of DSSC, the quality of DSSC, material consumption, auxiliary facilities and many other factors, it is crucial that the performance of DSSC can be accurately predicted....
