Doping of sputtered amorphous-silicon solar cells

The paper describes the progress that has so far been made in the sputtering of amorphous silicon for solar-cell applications. An alternative form of doping to doping from the gas phase is described. The results obtained are compared with those found for glow-discharge silicon. Finally, a discussion of the relative advantages of sputtering techniques emphasises their considerable potential for commercial exploitation in the production of thin-film solar cells.
