摘要： A low-reflection-loss low-angle-sensitive colored photovoltaic (PV) module is described. This colored PV module includes a transparent substrate; an array of solar cells encapsulated between a top encapsulation sheet and a bottom encapsulation sheet; and a color filter structure embedded between the top encapsulation sheet and the transparent substrate and configured to cause wavelength-selective reflections of incident light received by the colored PV module. Moreover, the transparent substrate includes a flat front surface configured to receive the incident light and a texture back surface configured with an array of features. The color filter structure is formed on the textured back surface of the transparent substrate to create a textured interface between the textured back surface and the color filter structure.
