Patent ID: 8460983

Claim:
A method of forming a doped silicon film, comprising the steps of: a) coating or printing a composition onto a substrate, the composition comprising a formulation including a Group IVA compound containing at least five Si and/or Ge atoms, a dopant in an amount effective to provide a film with a dopant atom concentration of from 0.1 to 50 ppm, relative to the number of Group IVA atoms, and a solvent; b) heating the coated or printed composition sufficiently to form a doped, amorphous, hydrogenated semiconductor; and c) annealing and/or irradiating the doped, amorphous, hydrogenated semiconductor sufficiently to at least partially crystallize, reduce a hydrogen content of, and/or electrically activate the dopant in the doped, amorphous, hydrogenated semiconductor and form the doped semiconductor film.
