Aiming widespread use of wireless power transmission, optical wireless power transmission at wavelength of 975 nm between vertical cavity surface emitting laser (VCSEL) arrays and a single crystalline Si solar cell was studied. The power generation efficiency of the cell was measured as high as 33% which was higher than the efficiency of 18% at the time of irradiation with sunlight. This is because the transmission loss is mainly eliminated. However, further reduction of the electrical resistance of the solar cell is necessary because the efficiency decreases with increasing incident energy.
