Tohoku University Technology: Photoelectric conversion device (Optical rectenna): T19-437
The antenna captures light and extracts it as power ―Enables photoelectric conversion of MIR&FIR―
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.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
