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.
Claims20
A solar roof tile, comprising:
- 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, wherein 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.
2 more elements
A cover for a solar roof tile, comprising:
- a layer of glass, which comprises a first surface facing incident sunlight and a second surface facing a plurality of photovoltaic structures encapsulated within the solar roof tile;
- and
- a band-stop optical filtering layer positioned on the second surface of the glass layer, wherein the band-stop optical filtering layer 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.
