| 摘 要： | 稀土红外量子剪裁为目前国内外的研究热点，它对于提高太阳能电池的效率从而减低太阳能发电的造价很有意义。论文综述了稀土红外量子剪裁的研究意义，在总结了太阳能电池发电和损耗的原理的基础上，分析了稀土红外量子剪裁提高太阳能电池效率的具体途径。同时综述了单掺Er3+材料的稀土红外量子剪裁发光现象：光激发2H11/2能级有很强的4I13/2→4I15/2红外量子剪裁发光，速率很大的{2H11/2→4I9/2，4I15/2→4I13/2}交叉能量传递为导致光激发2H11/2能级有高量子剪裁效率的主要原因。 |

| Abstract: | Infrared quantum cutting of rare earth ion is an international hot research field. It is significant for the enhancement of solar cell efficiency and for the reduction of solar cell price. The present paper summarizes the research significance of infrared quantum cutting of rare earth ion. Based on the summarization of general principle and loss mechanism of solar cell, the possible method to enhance the solar cell efficiency by infrared quantum cutting is analyzed. Meanwhile, the present paper summarizes the infrared quantum cutting phenomena of Er3+ ion single-doped material. There is intense 4I13/2→4I15/2 infrared quantum cutting luminescence of Er3+ ion when the 2H11/2 energy level is excited. The intense {2H11/2→4I9/2，4I15/2→4I13/2} cross energy transfer is the main reason for the result in the high quantum cutting efficiency when the 2H11/2 energy level is excited. |
