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 an optical filter positioned between the front cover and the photovoltaic structures. The 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.
Claims18
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
- an optical filter positioned between the front cover and the one or more photovoltaic structures, wherein the optical filter comprises:
- an optical absorbing layer,
- a first anti-reflection (AR) coating positioned on a first surface of the optical absorbing layer, and
- a second AR coating positioned on a second surface of the optical absorbing layer.

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
- an optical filter positioned on the second surface of the glass layer, wherein the 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, the optical filter, comprising:
- an optical absorbing layer,
- a first anti-reflection (AR) coating positioned on a first surface of the optical absorbing layer, and
- a second AR coating positioned on a second surface of the optical absorbing layer.
