摘要：

Procedures at NREL and Fraunhofer ISE for evaluating multijunction cells are detailed with a triple-junction GaInP/GaAs/Ge concentrator cell designed and grown at Spectrolab and processed at NREL [1], and a tandem Fraunhofer ISE Ga0.35In0.65P/Ga0.83In0.17As [2] cell as examples. The one-sun efficiency and Ix for the triple-junction device measured at Fraunhofer ISE and NREL agreed within 0.2%, well below the +/-6% uncertainty estimated by NREL. The procedures for determining the one-sun characteristics involve determining the quantum efficiency and using it for spectral correction during the I-V-characterization. The characteristics under concentration are evaluated with a flash simulator.
