The invention relates to silver paste on the obverse side of a silicon solar cell. The silver paste comprises, by weight, 4.8-20% of organic carriers, 80-95% of silver powder, 0.1-10% of glass powder and 0.1-10% of inorganic additives. According to the silver paste on the obverse side of the silicon solar cell, conversion efficiency is high, the silver powder with the specific surface of 0.6-1.2 square meters per gram is adopted to meet performance requirements of a battery piece, production cost is low, surface contact between the metal silver powder and a silicon wafer is guaranteed, and photovoltaic conversion efficiency is guaranteed; a silver conducting layer compact and uniform in sintering is obtained finally, and the silver paste is suitable for large-scale popularization and application.
