  • System and method for improving color appearance of solar roofs
    Patent number: 11955921
    Abstract: One embodiment can provide a photovoltaic roof tile. The photovoltaic roof tile can include a transparent front cover, a transparent back cover, and a plurality of polycrystalline-Si-based photovoltaic structures positioned between the front cover and the back cover. A respective polycrystalline-Si-based photovoltaic structure has a front surface facing the front cover and a back surface facing the back cover. The photovoltaic roof tile can further include a paint layer positioned on a back surface of the back cover facing away from the front cover. A color of the paint layer substantially matches a color of the front surface of the respective polycrystalline-Si-based photovoltaic structure.
    Type: Grant
