Problems solved by technology

An important step in the preparation of dye-sensitized solar cells is the preparation of the photoanode, which generally has a structure of conductive glass / titanium dioxide (TiO 2 ) / dye, where TiO 2 Sintering at a temperature above 450°C is generally used to obtain a dense structure. Therefore, for flexible batteries based on polymer substrates and solar cells prepared by low-temperature methods, high-temperature sintering cannot be used, resulting in the subsequent process of soaking dyes. ,TiO 2 Adsorption of dye by layer is not ideal

Abstract

The invention provides an anode dye soaking device of a solar cell and further provides a dye soaking method of using the anode dye soaking device of the solar cell. According to the method and the device, the dye adsorption effect on a flexible dye-sensitized solar cell and a dye-sensitized solar cell prepared at a low temperature is ideal, the volatilization speed of a dye can be effectively controlled, the dosage of the dye is displayed and the preparation technology is easily regulated and controlled; meanwhile, decomposition and dissociation of an oxide semiconductor thin film of which the structure is not compact enough when soaked into a solution are avoided; the dosage of the dye is effectively reduced; the material utilization rate is improved; and the soaking quality is improved.

Description

technical field [0001] The invention belongs to the technical field of solar cell production, and in particular relates to a solar cell anode dye sealing and soaking device and a dye soaking method. Background technique [0002] Clean energy is a topic that must be paid attention to in today's society, and it involves the country's environmental protection and green development strategy. An important step in the preparation of dye-sensitized solar cells is the preparation of the photoanode, which generally has a structure of conductive glass / titanium dioxide (TiO 2 ) / dye, where TiO 2 Sintering at a temperature above 450°C is generally used to obtain a dense structure. Therefore, for flexible batteries based on polymer substrates and solar cells prepared by low-temperature methods, high-temperature sintering cannot be used, resulting in the subsequent process of soaking dyes. ,TiO 2 Adsorption of the dye by the layer is not ideal. Contents of the invention [0003] In v...
