Patent ID: 8486282

Claim:
A method of texturing a transparent conductive oxide (TCO) layer, comprising providing a substrate comprising a TCO; applying a texturing formulation to the substrate to texture the TCO, and using the texturing formulation to etch the TCO such that the etched TCO exhibits increased light scattering, wherein the texturing formulation comprises a surface passivating acid and a passivation surface modifier selected from n-octadecyldimethylmethoxysilane, 2-(methoxypolyethylyneoxy)-propyl)trimethoxysilane, n-octyldimethylchlorosilane, noctadecyldimethyl(dimethylamino)silane, (tridecafluoro-1,1,2,2- tetrahydrodecyl)triethoxysilane, 3-mercaptopropyltrimethoxysilane, 3-(N,N-dimethylaminopropyl)trimethoxysilane, or 3-aminopropyltriethoxysilane.
