Abstract
Color photovoltaic (PV) devices formed using interferometric stacks tuned to reflect color covering the front side or back side of a PV cell, device, panel, or array are disclosed. Interferometric stacks covering PV devices include interferometric modulators (IMODs), or dichroic pair stacks. Such devices can be configured to reflect enough light of select wavelengths so as to impart a color, while transmitting enough light to the PV active material so as to generate useful electricity.
