Abstract:
1. A process for producing a layer comprising zinc oxide on a substrate, the process comprising: (A) applying a porous layer comprising zinc oxide to a substrate, (B) treating the porous layer of (A) with a solution comprising a precursor compound of zinc oxide, to at least partly fill pores of the porous layer with the solution, to obtain a solution-treated porous layer, and (C) thermally treating the solution-treated porous layer of (B) to convert the precursor compound to zinc oxide, wherein the precursor compound in (B) is at least one compound selected from the group consisting of the compound of the formula (III) the compound of the formula (IV) the compound of the formula (IVa) Zn[(NH the compound of the formula (IVb) the compound of the formula (IVc) at least one zinc alkoxide of a formula selected from the group consisting of (Va), (Vb), and (Vc) [(OH) a mixture thereof.
