Patent ID: 8288196

Claim:
A process for fabricating a photovoltaic cell, comprising: a) depositing a p-doped or n-doped amorphous silicon film, an X-ray diffraction spectrum of which has a line centered at between 27.9Â° and 28.1Â° having a mid-height width, denoted a, such that 4.7Â°<a<6.0Â°, by electron beam physical vapor deposition (EBPVD) on a substrate heated to a temperature T such that 400Â° C.<Tâ‰¦480Â° C. at a pressure P of between 1Ã—10 âˆ’7 mbar and 1Ã—10 âˆ’4 mbar inclusive and at a deposition rate of between 0.5 and 4 nm/s inclusive, and further comprising b) crystallizing the p-doped or n-doped amorphous silicon film by baking at a second temperature of between 545Â° C. and 655Â° C. inclusive.
