1. An optical device comprising:
a substantially transparent substrate;
a first transparent conductive oxide (TCO) layer disposed on the substantially transparent substrate;
a bus bar disposed on the first TCO layer in a bus bar pad expose area of the substantially transparent substrate;
wherein a remaining area of the substantially transparent substrate includes a stack of one or more material layers comprising a titanium dioxide (TiO2) layer disposed on the first TCO layer; and
wherein the remaining area of the substantially transparent substrate also includes a second TCO layer disposed on top of the stack of one or more material layers.
