综述了III-V族太阳能电池的研究进展。III-V族化合物半导体用于空间太阳能电池、聚光太阳能电池和热光伏发电机。通过MOVPE和LPE外延生长三元和四元材料，我们可以实现各种带隙。具有不同带隙的多结太阳能电池是获得大于30%的效率所必需的。介绍了弗劳恩霍夫ISE研究所III-V族太阳能电池的最新研究成果。机械堆叠的GaAs/GaSb串联聚光太阳能电池在100 x AM1.5d下实现了31.1%的效率。在实际的室外条件下，测量了一个具有菲涅耳透镜的双端聚光器模块（486 cm（2））的效率为23%。
Research activities in the field of III-V solar cells are reviewed. III-V compound semiconductors are used for space solar cells, concentrator solar cells, and in thermophotovoltaic generators. The epitaxial growth of ternary and quaternary material by MOVPE and LPE allows us to realize various band gaps. Multi-junction solar cells with different band gaps are necessary to obtain efficiencies larger than 30%. Recent results of the III-V solar cell research at the Fraunhofer ISE are presented. A mechanically stacked GaAs/GaSb tandem concentrator solar cell achieved an efficiency of 31.1% under 100 x AM1.5d. An efficiency of 23% for a two-terminal concentrator module (486 cm(2)) with Fresnel lenses has been measured under realistic outdoor conditions.
