Patent ID: 8198115

Claim:
A method for manufacturing a solar cell, comprising: forming, on a silicon substrate whose conductivity type is p-type or n-type, a silicon layer including a dopant whose conductivity type is different from that of the silicon substrate, the silicon layer contacting the silicon substrate, and the silicon layer being formed by a chemical vapor deposition method; diffusing the dopant included in the silicon layer into the silicon substrate by heat-treating the silicon layer, wherein the dopant is diffused at a temperature higher than or equal to 600° C. and less than or equal to 1200° C.; generating a PN-junction within the silicon substrate; forming an anti-reflective film on the silicon layer after the silicon layer is formed; and forming a top electrode on the anti-reflective film, wherein when the dopant included in the silicon layer is diffused in the silicon substrate, the top electrode is electrically-conducted to the silicon layer or the silicon substrate and the dopant is diffused in the silicon substrate by heating the silicon substrate in which the silicon layer, the anti-reflective film, and the top electrode were formed.
