摘要： 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.
