We present a functional glass coating that embed several functionalities suitable for cover glass applications in solar energy harvesting applications, including omnidirectional anti-reflection, dynamic solar control, and self-cleaning. Yttrium hydride oxide (YHO) and sulphated titania (SO4-TiO2) thin films were deposited on the nanopillar structures using magnetron sputtering methods. Nanopillar terminated glass were achieved by colloidal lithography templating methods on iron free glass, realizing nanopillar structures with dimensions /2. The resulting nanopillar structures exploit Mie scattering for wide angle light collection. The YHO and SO4-TiO2 films block UV light and YHO photo-darkens upon solar light absorption with and reverts to its transparent state in darkness in reproducible manner with colour neutral spectral characters. The results demonstrate possibilities to increase e.g. solar cell device efficiency by smart cover glass materials without adding further control and maintenance solutions.
