Abstract:
1. A method for manufacturing a solar battery cell, the method comprising: a first step of forming a passivation film on a first surface of a crystalline silicon substrate of a first conductive type; a second step, after the first step, of diffusing an element of a second conductive type into a second surface of the crystalline silicon substrate by thermal diffusion to form a diffusion layer, whereby a pn junction is formed; a third step of forming an antireflection film on the diffusion layer; a fourth step of disposing a first electrode paste on the second surface of the crystalline silicon substrate; a fifth step of disposing a second electrode paste on the passivation film; and a sixth step of firing the first electrode paste and the second electrode paste to form electrodes.
