Crystalline Silicon Solar Cell an overview ...

The colour of crystalline silicon solar cells is determined by the width of the antireflective coating, a thin layer of silicon nitride that prevents reflection of solar energy from the cells. The colours we normally see in solar cells (, dark grey for single crystalline, dark blue for multicrystalline) are produced by the antireflective coating thickness that allows the highest efficiencies.
