ABSTRACT:
A method of manufacturing a solar cell includes forming a diffusion layer on a crystal-type silicon substrate. The diffusion layer has a conductivity opposite to that of the substrate. Furthermore, the method includes etching and removing a part of the diffusion layer by using sodium silicate, and forming a first electrode that makes an electric contact with the diffusion layer and forming a second electrode that makes an electric contact with the substrate.
