A front-side conductive paste for a crystalline silicon solar cell is provided. The front-side conductive paste for a crystalline silicon solar cell includes, in parts by weight, 80.0-93.0 parts of a metal powder, 6.0-15.0 parts of an organic carrier, and 1.0-5.0 parts of an oxide etching agent, where based on 100% by mole of the oxide etching agent, the oxide etching agent includes 15-30% of PbO; 25-40% of TeO2; 8.0-15.0% of Li2O; 9.0-20.0% of SiO2; 5.0-15.0% of Bi2O3; 0.5-10.0% of ZnO; and either one or both of 0.1-10.0% of MgO and 0.1-10.0% of CaO; and no more than 5.0% of an oxide of additional metal elements. The metal powder forms good ohmic contact with crystalline silicon substrate during the sintering process of the front-side conductive paste applied overlying an insulation film on the substrate. Finally, a front-side electrode of low contact resistance, good electrical conductivity, and strong adhesion is obtained.
