Abstract

The invention relates to an electrode material of a crystalline silicon solar cell, in particular to front-face electrode slurry with the low silver content for a silica-based solar cell main grid and a preparation method of the front-face electrode slurry. The front-face electrode slurry with the low silver content for the silica-based solar cell main grid is mainly formed by mixing, by weight, 65-75% of silver powder, 21-31% of organic bond, 1-8% of glass powder and 0.5-3% of inorganic additives. The front-face electrode slurry is used for crystalline silicon solar cell main grid lines, and developed for reducing the production cost and the manufacturing cost of the silica-based solar cell. The front-face electrode slurry is printed on the back face of the crystalline silicon solar cell, and forms a silver electrode with the high adhesive force and the high reliability on the main grid on the front face of the crystalline silicon solar cell through the infrared fast-burning process, wherein the actual peak temperature of the surface of a silicon wafer is 780-810 DEG C, and the peak time is 1-2s.

Description

technical field

[0001] The invention relates to an electrode material for a crystalline silicon solar cell, in particular to a front electrode paste with a low silver content for a main grid of a silicon-based solar cell and a preparation method thereof. Background technique

[0002] Crystalline silicon solar cell is a semi-permanent physical battery that converts sunlight energy into electrical energy. With the extreme consumption of fossil (petroleum, coal, natural gas, etc.) The demand for clean energy is becoming more and more urgent. For a long time in the future, the sun will be an effective provider of clean energy for human beings. At present, crystalline silicon solar cells are one of the effective devices for converting solar energy into civil energy. Its application range is expanding from aerospace, military, to people's Daily life, while not generating new pollution, the cost reduction will make solar cells more widely used.
