DIFFUSION BARRIERS FOR PHOTOVOLTAIC DEVICES BY LEACHING

摘要

A method of leaching alkali ions from a glass substrate to form a glass substrate having an intrinsic alkali barrier layer including providing a glass substrate comprising alkali metal ions, alkaline earth metal ions, or a combination thereof and contacting the surfaces of the substrate with a solution comprising a hydrogen bearing species such that at least a portion of the hydrogen bearing species replaces at least a portion of the alkali metal ions, alkaline earth metal ions, or the combination thereof in the at least one surface to form the glass substrate having the intrinsic alkali barrier layer.
