Abstract

The invention provides a method and equipment of preparing flexible photo-anodes for dye-sensitized solar cells, and ensures an obtained semiconductor film free of cracks and superior in good uniformity and controllable thickness. The invention solves the problems of the prior art, such as long preparation time, poor repeatability, random distribution of local surface density of the semiconductor film, and high cracking risk. The flexible photo-anode is obtained by spray-coating of a conductive substrate by using a high-voltage electrostatic method and has good surface uniformity, and the surface semiconductor film doesn't produce cracks after random bending, thereby substantially realizing the flexibility. The preparation method is performed at normal temperature and pressure, without needing sinter process, thereby saving production energy and making it possible for nano-sized semiconductor materials with poor heat resistance to be applied in the field. The invention provides a new approach to improve the quality of the dye-sensitized solar cells.
