Electrodeposition of CdTe for thin-layered photovol-ataics has been well investigated by many research groups.Although acidic aqueous sulfate solutions have historically been employed as the electrolytes in electrodeposition,we have proposed that ammoniacal basic aqueous solutions are also suitable,since the basic solutions have a relatively high solubility of Te(IV) species as TeO_3~(2-) ions.
