FRONT ELECTRODE INCLUDING TRANSPARENT CONDUCTIVE COATING ON PATTERNED GLASS SUBSTRATE FOR USE IN PHOTOVOLTAIC DEVICE AND METHOD OF MAKING SAME

摘要

This invention relates to a photovoltaic device including an electrode such as a front electrode/contact. In certain example embodiments, the front electrode of the photovoltaic device includes a multi-layered transparent conductive coating which is sputter-deposited on a textured surface of a patterned glass substrate. In certain example embodiments, a maximum transmission area of the substantially transparent conductive front electrode is located under a peak area of a quantum efficiency (QE) and/or QEx (photon flux of solar radiation) curve of the photovoltaic device and a light source spectrum used to power the photovoltaic device. In certain example embodiments, the front electrode includes a transparent conductive layer of or including one or more of (i) titanium zinc oxide doped with aluminum and/or niobium, and/or (ii) titanium niobium oxide.
