摘要
论述键合的双结GaAs/InGaAs太阳电池的研制,界面采用p^(++)GaAs/n^(++)GaAs隧穿结,开路电压大于1.15 V,效率比国际报道的同类键合两结电池提高0.3%,电池表面未做减反膜。开路电压表明两结电池可实现串联,为单片集成的高效多结电池提供新的途径,通过分析电池效率性能提出进一步提高效率的技术方案。
The two-junction bonding GaAs/InGaAs solar cell was developed. The solar cell interface used p＋＋GaAs/n＋＋ GaAs tunneling junction. The open circuit voltage is greater than 1.15 V. The efficiency increased 0.3% than the similar two-junction cell by other international laboratory, while the structure parameter is not optimized and the antireflective film wasn＇ t done. The open circuit voltage shows the two sub-solar cells were in series connection. It means that the bonding technology provides a new way for monolithic integration high efficient multi-junction cells. The improvement reasons of the efficiency are analyzed and the measures are given.
