A thin-film solar cell is provided. The thin-film solar cell comprises an
a-SiGe:H (1.6 eV) n-i-p solar cell having a deposition rate of at least
ten (10) .ANG./second for the a-SiGe:H intrinsic layer by hot wire
chemical vapor deposition. A method for fabricating a thin film solar
cell is also provided. The method comprises depositing a n-i-p layer at a
deposition rate of at least ten (10) .ANG./second for the a-SiGe:H
intrinsic layer.
