Keywords:wireless power transmission, light, solar panel

The power supply efficiency of optical wireless power transmission is the product of the efficiency of the laser and the solar cell the maximum, but the solar cell irradiation condition of the light beam also influences. Deformation of the beam shape affects the diagonal beam incident on the solar cell. Although it is possible to cope with complicated beam control, efficient power supply by a simple configuration is also desired. This research aims to elucidate the characteristic influence of light irradiation method in optical wireless power transmission. In this study, the irradiation characteristics when the focal length (divergence angle) variable and the light source size are different were examined.
