The main limited factors of solar photoelectric conversion efficiency is its spectral sensitive area is narrow, most of the sunlight irradiation on the battery has failed to effectively converted into electricity. Rare-earth complexes doped into the anti-reflection film of solar cells,in order to improve the efficiency,is a research hotspot in the field of solar energy in recent years.Rare earth Eu3+ complexes not only make part of the ultraviolet and visible light to convert to a wavelength which is more suitable for solar cell absorption and utilization of 612 nm red band, also can effectively shield against ultraviolet light on solar cell.This paper mainly introduces the turn light mechanism of rare earth Eu3+and its complexes, and its research progress in solar cells decreased reflector.%限制太阳能电池光电转换效率的主要因素是其光谱敏感区域比较狭窄,照射在电池上的大部分太阳光没能有效地转换成电能.将稀土铕配合物掺杂入太阳能电池减反射层中以此来提高太阳能电池效率是近年来太阳能领域的研究热点.稀土铕配合物不仅使部分紫外及可见光转换为波长更适合太阳能电池吸收利用的612nm红光波段,还能有效屏蔽对太阳能电池不利的紫外光,如能将其合理有效地在太阳能电池中加以利用,势必会对太阳能电池的光电转换效率产生重要影响.本文主要介绍稀土铕元素及其配合物的转光机理和其在太阳能电池减反射层中的研究进展.
