A method for manufacturing a solar cell includes disposing a first doping layer on a substrate, disposing a diffusion preventing layer on the first doping layer, patterning the first doping layer and the diffusion preventing layer to expose a portion of the substrate, forming a second doping layer which is disposed on the exposed portion of the substrate on the diffusion preventing layer, diffusing an impurity from the first doping layer to form a first doping region in a surface of the substrate and diffusing an impurity from the second doping layer to form a second doping region in the surface of the substrate surface, wherein the exposed portion of the substrate formed by patterning the first doping layer and the diffusion preventing layer and a portion of the remaining first doping layer and the diffusion preventing layer which are not patterned are alternately arranged with a lattice shape, and the first doping region and the second doping region are alternately arranged with the lattice shape. |
