Patent ID: 8268714

Claim:
A method for fabricating a solar cell comprising a first electrode, a first-type layer, an intrinsic layer, a second-type layer and a second electrode, the method comprising: preparing a first-type Si substrate; forming a first electrode on a rear surface of the first-type Si substrate; forming an intrinsic layer on a front surface of the first-type Si substrate; forming a second-type layer including an amorphous silicon (Si) carbide thin film by an inductively coupled plasma chemical vapor deposition (ICP-CVD) device using mixed gas including hydrogen (H 2 ) gas, silane (SiH 4 ) gas, diborane (B 2 H 6 ) and ethylene (C 2 H 4 ) gas, wherein the ethylene (C 2 H 4 ) gas includes 60% hydrogen gas diluted ethylene gas, the diborane gas is 97% hydrogen gas diluted diborane gas, the mixed gas includes 1 to 1.2% ethylene gas and 6 to 6.5% diborane gas; and forming a second electrode on the second-type layer.
