SOITEC : NEW WORLD RECORD FOR SOLAR CELL EFFICIENCY AT 46%
由Soitec公司、法國CEA-Leti、德國Fraunhofer ISE共同研發III-V族四接面太陽能電池，由日本AIST測試實驗室在聚光強度508個太陽光強度下，測到46%，寫下聚光型太陽能電池的世界紀錄。
Multi-junction solar cells are based on a selection of III-V compound semiconductor materials. The world record cell is a four-junction cell, and each of its sub-cells converts precisely one quarter of the incoming photons in the wavelength range between 300 and 1750 nm into electricity. When applied in concentrator PV, a very small cell is used with a Fresnel lens, which concentrates the sunlight onto the cell. The new record 46.0% efficiency was measured at a concentration of 508 suns and has been confirmed by the Japanese AIST (National Institute of Advanced Industrial Science and Technology), one of the leading centers for independent verification of solar cell performance results under standard-testing conditions.
