摘要
Disclosed are a conductive silver paste for the front surface of a crystalline silicon solar cell and a preparation method therefor and a solar cell. The conductive silver paste for the front surface of a crystalline silicon solar cell comprises the following raw materials in part by weight: 80.0~93.0 parts of metal powder; 6.0~15.0 parts of organic carrier; 1.0~5.0 parts of glass powder; and 0.06~3.75 parts of silicone oil; the silicone oil is at least one selected from the group consisting of methyl silicone oil, ethyl silicon oil, phenyl silicone oil, methyl hydrogen-containing silicone oil, methyl phenyl silicone oil, methyl chlorophenyl silicone oil, methyl-ethyloxy silicone oil, methyl trifluoropropyl silicone oil, methyl vinyl silicone oil, methyl hydroxy silicone oil, ethyl hydrogen-containing silicone oil, hydroxy hydrogen-containing silicone oil, and cyanide-containing silicone oil. The conductive silver paste has excellent fine grid wire screen printing performance, can be printed on a screen printing plate with a 23 μm opening, and finally obtains a front surface electrode having excellent aspect ratio, so that the solar cell has the characteristics of high current and high conversion rate.
