Abstract
Certain example embodiments of this invention relate to an electrode (e.g., front electrode) for use in a photovoltaic device or the like. In certain example embodiments, a transparent conductive oxide (TCO) based front electrode for use in a photovoltaic device is of or includes zinc oxide, or zinc aluminum oxide, doped with yttrium (Y). In certain example embodiments, the addition of the yttrium (Y) to the conductive zinc oxide or zinc aluminum oxide is advantageous in that potential conductivity loss of the electrode can be reduced or prevented. In other example embodiments, a low-E coating may include a layer of or including zinc oxide, or zinc aluminum oxide, doped with yttrium (Y).
