PHOTOVOLTAIC MODULES WITH A CONTROLLED COLOR ON THEIR WINDOW SURFACE AND ARRAYS THEREOF

摘要

Thin film photovoltaic devices are provided that include a transparent substrate defining an inner surface and an outer surface; a thin film stack on the inner surface of the transparent substrate; an encapsulation substrate on the thin film stack; and a color reflection film on the outer surface of the transparent substrate. The thin film stack has a photovoltaic heterojunction (e.g., formed from a n-type window thin film layer and an absorber thin film layer). Generally, the color reflection film comprises a colorant, such as a refractive material (e.g., a nitride material, an oxide material, or mixtures thereof). Methods are also provided for forming such a photovoltaic device, and for forming an array of photovoltaic devices to define an image.
