Abstract: The present invention relates to a composite substrate with high thermal conductivity and applicable to concentrating solar power generating plates. The thermal conducting substrate and the circuit substrate are manufactured, respectively, for separating the light concentrating area and the circuit area so that the material with high thermal conductivity can be used completely to the thermal conducting substrate for guiding heat. Then, the material having common thermal conductivity can be chosen as the material for the circuit substrate, which needs no extra thermal conduction. Thereby, regarding to the selection of substrate material, the present can balance well between thermal conducting efficiency and cost control.
