Photoelectric conversion device (Optical rectenna)

The antenna captures light and extracts it as power
―Enables photoelectric conversion of MIR&FIR―

Overview

　Rectenna composed of an antenna and a diode is known as a device for converting electromagnetic waves into electric power. The rectenna absorbs electromagnetic waves with an antenna and performs photoelectric conversion. In recent years, research on optical rectennas, in which rectenna technology is applied to the optical frequency domain, has been advanced, and results of photovoltaic power generation have been reported. However, the optical rectennas reported at present are difficult to manufacture or have low efficiency.　
　The present invention has succeeded in significantly increasing the photoelectric conversion efficiency by introducing a special structure and material into the metal-dielectric-metal (MIM) tunnel diode and established an device based on hollow resonators.
