Uniformly and directionally colored photovoltaic modules

A photovoltaic roof tile, comprising:

• a front glass cover having a front surface and a back surface, wherein the back surface is textured, wherein the textured back surface comprises at least a first set of facets facing a first direction and a second set of facets facing a second direction, and wherein a respective facet is further textured using a layer of sphere shaped metal nanoparticles;
• a back cover facing the back surface of the front cover;
• and
• a plurality of photovoltaic structures positioned between the front glass cover and the back cover;
• and
• a directional color filter positioned between the back surface of the front glass cover and the plurality of photovoltaic structures, wherein the directional color filter is configured to directionally reflect light of a first color, wherein the directional color filter is deposited directly on the first and second sets of facets, and wherein a thickness of the directional color filter on the first set of facets is larger than a thickness of the directional color filter on the second set of facets.

A directionally colored photovoltaic roof tile, comprising:
