Optical wireless power transmission systems incorporating photovoltaic cells and lasers are expected to serve as next-generation energy supply devices for automobiles and autonomous underwater vehicles. High photoelectric conversion efficiencies over 40% of photovoltaic converters under high-power irradiation over 10Wcm⁻² are required for the practical application in these applications. We achieved a high conversion efficiency of 43.0% of GaInP photonic power converter under high-power 638nm laser irradiation of 17.0Wcm⁻² by incorporating multi-crossed finger electrodes and a distributed Bragg reflector. The highest efficiency, 46.0% of GaInP converter cell, was also obtained at 1.1Wcm⁻² laser irradiation.
