Abstract
A layered construct including: a substrate, a transparent electrically conductive layer positioned along an upper surface of the substrate, and an index-matching layer positioned adjacent the transparent electrically conductive layer that reduces the refractive index differential between the transparent electrically conductive layer and the substrate.
Claims23
A layered construct comprising:
- a substrate;
- a transparent electrically conductive layer positioned along an upper surface of the substrate;
- and
- an index-matching layer positioned adjacent the transparent electrically conductive layer, said index-matching layer comprising:
- a metal oxide layer containing titanium and having a refractive index of at least 1.5, the metal oxide layer having the structure below:
- wherein each R1 is an independent hydrogen, an alkyl group having 1 to 6 carbons, alkylene oxide, or titanium connected groups
- wherein each R2 is an independent hydrogen or an alkyl group.
