在1个太阳、0个空气质量的光照下，在双端AlGaAs/GaAs/InGaAsP三结太阳能电池中测得25.2%的效率。级联电池由单片AlGaAs（E（g）= 1.93 eV）/GaAs双结机械堆叠在InGaAsP（E（g）= 0.95 eV）单结电池上组成。AlGaAs/GaAs双结结构的元件单元使用在后生长处理期间制造的金属互连进行电连接。为了最小化由栅线和金属互连引入的遮蔽效应，将棱镜盖玻璃结合到AlGaAs/GaAs级联电池。用这种结构获得的结果代表了在双端子配置下操作的任何太阳能电池中实现的最高的1太阳、空气质量0效率。实现这一高效率的两个终端，三结太阳能电池的陆地和空间应用的影响进行了说明。
A 25.2% efficiency measured under 1 sun, air mass 0 illumination has been achieved in a two-terminal AlGaAs/GaAs/InGaAsP three-junction solar cell. The cascade cell consists of a monolithic AlGaAs (E(g) = 1.93 eV)/GaAs two-junction mechanically stacked on an InGaAsP (E(g) = 0.95 eV) single-junction cell. The component cell of the AlGaAs/GaAs two-junction structure were electrically connected using a metal interconnect fabricated during post-growth processing. To minimize the obscuration effect introduced by the grid lines and metal interconnect, a prismatic cover glass was bonded to the AlGaAs/GaAs cascade cell. The results obtained with this structure represent the highest 1-sun, air mass 0 efficiency achieved in any solar cell operating under a two-terminal configuration. The implications of achieving this high efficiency in a two-terminal, three-junction solar cell for terrestrial and space applications are described as well.
