Keywords:Optical wireless power transmission, OWPT, solar cell

Optical wireless power transmission (OWPT) system is an attractive photonic system using light source and solar cell. Since most of solar cells are designed for sunlight, the surface of solar cells becomes black in order to absorb various wavelengths of light. Such surface property of solar cells can cause lack of design possibilities of equipment appearance used in our daily life. In the practical application of OWPT, this characteristic will become an obstacle.In this research, we are investigating the possibility of controlling appearance of solar cell surface used for OWPT considering maintaining power transmission efficiency. In this time, color and power transmission performance of wavelength filters are investigated. As the result, it is possible to change the surface appearance of solar cells to some extent without large deterioration of OWPT performance.
