Patent ID: 8338221

Claim:
A method for manufacturing a thin film type solar cell comprising: forming a front electrode layer on a substrate; sequentially depositing P-type, I-type, and N-type semiconductor layers on the front electrode layer; and forming a rear electrode layer on the N-type semiconductor layer, wherein the process for forming the I-type semiconductor layer comprises forming an amorphous silicon layer by a plasma CVD method under such circumstances that a chamber pressure is maintained at a range between 2.0 Torr and 2.4 Torr, and a substrate temperature is maintained at a range between 225° C. and 250° C., and a content ratio of silicon-containing gas to hydrogen-containing gas is within a range between 1:7 and 1:10, wherein the process for forming the I-type semiconductor layer comprises forming an amorphous silicon layer at a deposition rate of 200 Å/min to 250 Å/min.
