Abstract
A protective layer is disposed between a silver reflective electrode and a layer of transparent conductive oxide in a photovoltaic device so as to prevent oxidation of the silver. The protective layer may be continuous or discontinuous and may be fabricated from MgF.sub.2, Si.sub.x N.sub.y or T.sub.ix N.sub.y where x and y are positive numbers.
