Abstract
Metal chalconide films having improved photo-electrical properties are obtained from electrodeposition baths containing solvents having a low power for solvating metal cations such that decreased quantities of solvent molecules become intercalated into the chalconide film.
Claims38
A bath for the electrodeposition of metal chalconides comprising an organic polar solvent having dissolved therein (a) an ionized salt of at least one metal selected from the group consisting of Cd, Pb, Hg, Cu, Bi, Co, Ni, Tl, Ag, In, and Fe, and (b) at least one chalcogen in elemental form selected from the group consisting of S and Se said solvent being characterized by having a power of intercalation into metal chalconide films electrodeposited therefrom lower than that of dimethylsulfoxide and having power for dissolving elemental chalcogen greater than that of ethylene glycol.
