Transmissive color filters with a function of photoelectric conversion were proposed. They consisted of metal-insulator-metal (MIM) metamaterials in which p-i-n photodiodes made of amorphous silicon were embedded. Since MIM metamaterials are formed on a transparent substrate, the proposed devices can be used as wavelength-selective see-through filters and windows that can extract electric energy. We successfully fabricated the devices and observed transmissive colors and photo current under white light illumination. The transmittance spectra and current-voltage characteristics were experimentally investigated.
