Abstract: One embodiment can provide a photovoltaic roof tile module. The photovoltaic roof tile module can include a front encapsulant layer and a back encapsulant layer where both the front and back encapsulant layers include different pigments. The front encapsulant layer can include a small amount of pigment that absorbs and scatters particular frequencies of visible light to give the photovoltaic roof tile a desired color. The small amount of pigment does not absorb or scatter a significant amount of infrared light. Two or more photovoltaic roof tiles can be combined to form a photovoltaic module. The two or more photovoltaic roof tiles can have different concentrations of pigment in the front encapsulant layer to give the photovoltaic module a small amount of color variation.

Abstract: One embodiment can provide a photovoltaic roof tile (200). The photovoltaic roof tile can include a transparent front cover (204), a transparent back cover (206), and a plurality of polycrystalline-Si- based photovoltaic structures (202) 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 further includes a paint layer (212) 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.
