| Outline of Final Research Achievements |
Optical rectenna is a new photo-voltaic conversion system that expected to break through the limit efficiency of existing system. The most important technology to realize this device is ultra-high speed diodes to rectify optical light frequency (>100THz) and controlling broad solar spectrum into narrow band emission. In this study, we developed a technique to control broad thermal radiation spectrum into quasi-monochromatic thermal emission. For the diode, we suppose to apply geometrical e-field enhancement in order to improve response frequency and quantum efficiency of Metal-Insulator-Metal (MIM) tunnel diode that is one of the most hopeful rectifier for optical rectenna.
