Keywords:Optical power transmission system

Optical wireless power feed attracts attention in recent years due to advantages such as possible long distance transmission and less leakage of electromagnetic waves. Since the light receiving device that converts light from electricity has a structure similar to that of a solar cell, by using a light with a short wavelength and a light absorbing material with a large band gap, a voltage defined as a ratio of an open end voltage to an incident light energy Efficiency can be improved. This time, we assumed a device that receives blue laser light. AlGaInP could be shortened to 570 nm by using the inclined substrate.
