An antioxidant conductive copper paste and a method for preparing the same are revealed. The antioxidant conductive copper paste includes conductive particles, a pasting agent, and a solvent. The conductive particles are copper nanoparticles or copper alloy nanoparticles. The pasting agent can be ethyl cellulose, Poly(3,4-ethylenedioxythiophene) (PEDOT), or epoxy. The solvent can be terpineol, ethylene glycol or diethylene glycol. The antioxidant conductive copper paste with features of high stability and low cost can be applied to produce electrodes of heterojunction solar cells.
