Glass cover with optical-filtering coating for managing color of a solar roof tile

Abstract:

One embodiment can provide a solar roof tile. The solar roof tile can include a front cover, a back cover, one or more photovoltaic structures positioned between the front cover and the back cover, and a band-stop optical filter positioned between the front cover and the photovoltaic structures. The band-stop optical filter is configured to block light within a predetermined spectral range, thereby preventing the light from reflecting off surfaces of the photovoltaic structures to exit the solar roof tile.
