首次实现了具有五个有源结（即AlGaInP、GaInP、AlGaInAs、GaInAs和Ge）的单片多结III-V太阳能电池。测得开路电压为 4826 mV。由于每个子电池的厚度仅在 120-1600 nm 范围内，因此这些电池预计将受益于卓越的辐射硬度。单个子电池的 IV 特性或量子效率等重要参数的测量极具挑战性，但首次测量取得了成功，并在本文中进行了讨论。
Monolithic multi-junction III-V solar cells with five active junctions, namely AlGaInP, GaInP, AlGaInAs, GaInAs and Ge have been realized for the first time. An open circuit voltage of 4826 mV was measured. The cells are expected to benefit of a superior radiation hardness as the thickness of each individual subcell is only in the range of 120-1600 nm. The measurement of important parameters like the IV-characteristics or the quantum efficiency of individual subcells is extremely challenging but first measurements were successful and are discussed in this paper.
