Tellurium counter electrode, solar battery with same and manufacturing method thereof

Abstract

A tellurium counter electrode is a conductive glass substrate with telluride. The telluride is one of cobalt telluride and nickel telluride or a mixture of the cobalt telluride and the nickel telluride. A manufacturing method of the tellurium counter electrode includes manufacturing a reaction raw material of the tellurium counter electrode; conducting low temperature reaction, arranging a reaction mixture into a reaction kettle, sealing the kettle and arranging the kettle into a drying box with preset temperature for reaction; conducting cooling washing; conducting high temperature sintering, arranging a dried solid object into a tubular furnace and conducting sintering under the nitrogen atmosphere; manufacturing the tellurium counter electrode. A solar battery adopts the tellurium counter electrode, and greatly improves the photoelectric conversion efficiency. The tellurium counter electrode is low in cost and meets the industrial production requirement. Meanwhile, the manufacturing method of the tellurium counter electrode adopts a low temperature reaction and high temperature sintering process, the obtained tellurium counter electrode is excellent in catalytic performance, the manufacturing process is simple, and the rigorous condition required by a traditional manufacturing process is avoided.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a counter electrode containing tellurium, a solar cell with the counter electrode and a manufacturing method thereof. Background technique [0002] Dye Sensitized Solar Cells (DSCs) have attracted widespread attention due to their advantages such as simple production process, low manufacturing cost, high theoretical photoelectric conversion efficiency, and good application prospects. In terms of production cost, the production cost of dye-sensitized solar cells is only 1 / 5-1 / 10 of the production cost of traditional silicon solar cells, and its theoretical service life can reach more than 20 years. [0003] As is well known, in a dye-sensitized solar cell, the counter electrode is mainly used to transport electrons from the photoanode, and to catalyze the reduction reaction of the redox couple in the electrolyte. At present, the counter electrode of existing dye-sensitized s...
