Optical wireless power transmission (OWPT) has characteristics of long-distance power transmission and no leakage of electromagnetic waves compared to existing wireless power transmission. In previous research when the beam was perpendicularly irradiated on solar cell, optimum focused condition was effective for wide transmission distance of OWPT system, because of transmission distance dependence of lens magnification under fixed lens position and variable focal length of liquid lens. In this research, we investigated the influence of focusing condition on the power generation efficiency when the beam is obliquely irradiated on solar cell by experiment.
