Abstract:
In manufacturing a crystalline silicon-based solar cell, a first intrinsic thin-film is formed on a conductive single-crystalline silicon substrate, and then a hydrogen plasma etching is performed. A second intrinsic thin-film is formed on the first intrinsic thin-film after the hydrogen plasma etching, and a conductive silicon-based thin-film is formed on the second intrinsic thin-film. The second intrinsic thin-film is formed by plasma-enhanced CVD with a silicon-containing gas and hydrogen being introduced into a CVD chamber. The amount of the hydrogen introduced into the CVD chamber during formation of the second intrinsic thin-film is 50 to 500 times an introduction amount of the silicon-containing gas.

Claim (Index 13):
The method according to  claim 11 , wherein\n a total plasma etching amount is 0.5 to 5 nm, wherein the total plasma etching amount is a sum of a plasma etching amount in the intermediate hydrogen plasma treatment performed after formation of each of the first to (n\u22121) th  sublayers and a plasma etching amount in the hydrogen plasma etching performed after formation of the n th  sublayer, and the thickness of the second intrinsic thin-film is 0.5 to 2 times the total plasma etching amount.
