Method for preparing counter electrode of dye-sensitized solar cell

Abstract

The invention discloses a method for preparing a counter electrode of a dye-sensitized solar cell, which comprises the following steps of: (1) weighing chloroplatinic acid and isopropanol, and fully mixing the chloroplatinic acid and the isopropanol to prepare solution A; (2) weighing ethyl cellulose and terpineol, and fully mixing the ethyl cellulose and the terpineol to prepare solution B; (3) mixing and stirring the solution A and the solution B to prepare a platinum sizing material for screen printing; (4) taking a piece of conductive glass, printing the platinum sizing material on the conductive glass through screen printing, and dying and sintering the conductive glass to obtain an initial platinum electrode; and (5) soaking the initial platinum electrode in aqueous solution of TiCl4, taking the initial platinum electrode out of the aqueous solution of TiCl4, washing the initial platinum electrode, raising the temperature in a muffle furnace to between 400 and 550 DEG C and keeping the temperature for 20 to 60 minutes to prepare the needed counter electrode. Because the counter electrode prepared by the method has a large specific area, and the conversion efficiency of the cell is high, the method is favorable for industrialized development.

Description

【Technical field】

[0001] The invention relates to a solar cell, in particular to a method for preparing a counter electrode of a dye-sensitized solar cell. 【Background technique】

[0002] Since entering the 21st century, energy and environmental issues facing mankind have become increasingly prominent. On the one hand, there is a huge demand for energy from economic development; on the other hand, the traditional fossil energy such as coal, oil, and natural gas, which have been accumulated for hundreds of millions of years, has been irreversibly exhausted after hundreds of years of huge consumption, and the development and utilization of traditional fossil energy The process will cause serious harm to the ecological environment. Therefore, these two practical issues have become the focus of attention in recent years.

[0003] Solar energy is the green renewable energy with the most widespread distribution and the largest amount of resources on the earth. Compared with othe...
