摘要

高性能太阳能电池的发展为许多应用提供了一条实现高单位成本功率的有希望的途径。由于目前单结太阳能电池的效率已接近Shockley-Queisser极限,因此多结(MJ)太阳能电池对高效太阳能电池非常有吸引力。本文综述了III-V型化合物单结和MJ太阳能电池的研究进展。此外,本文还给出了III-V化合物单结和MJ太阳能电池的效率势、非辐射复合和电阻损耗的分析结果,以进一步了解和减少III-V化合物材料和MJ太阳能电池的主要损耗。结果表明,GaAs单结、III-V 2结和III-V 3结太阳能电池的潜在效率分别为30%、37%和47%。虽然在开发的初始阶段,砷化镓单结和III-V MJ太阳能电池的ERE值较低,但由于器件结构和材料质量等技术的发展,ERE值得到了改善。在III-V MJ太阳能电池的情况下,改进亚电池的ERE被证明是进一步提高MJ太阳能电池效率的必要条件。

Overview and loss analysis of III–V single-junction and multi-junction solar cells
The development of high-performance solar cells offers a promising pathway toward achieving high power per unit cost for many applications. Because state-of-the-art efficiencies of single-junction solar cells are approaching the Shockley-Queisser limit, the multi-junction (MJ) solar cells are very attractive for high-efficiency solar cells. This paper reviews progress in III–V compound single-junction and MJ solar cells. In addition, analytical results for efficiency potential and non-radiative recombination and resistance losses in III–V compound single-junction and MJ solar cells are presented for further understanding and decreasing major losses in III–V compound materials and MJ solar cells. GaAs single-junction, III–V 2-junction and III–V 3-junction solar cells are shown to have potential efficiencies of 30%, 37% and 47%, respectively. Although in initial stage of developments, GaAs single-junction and III–V MJ solar cells have shown low ERE values, ERE values have been improved as a result of several technology development such as device structure and material quality developments. In the case of III–V MJ solar cells, improvements in ERE of sub-cells are shown to be necessary for further improvements in efficiencies of MJ solar cells.
