Popis:	An effective cooling method is essential for GaAs concentrator solar cells operated under highly concentrated sunlight, because the conversion efficiencies of the cells decrease at high temperature. We fabricated aluminum-cored printed circuit bases which consist of an aluminum core, anodic oxide layer of aluminum, polymer layer such as polyimide, and metal layer. In this paper we report that this aluminum-cored printed circuit base is effective and that on this base a higher conversion efficiency can be obtained than on a conventional alumina ceramic base. Cell conversion efficiencies of 23.9%, 23.7%, and 22.6% were obtained at 96 suns, 186 suns, and 327 suns, respectively, from the GaAs concentrator solar cell mounted on the aluminum-cored printed circuit base.
