摘　　要：制备了一种大分子稀土配合物聚6-(丙烯酰氧基)萘-2-羧酸-铕(p-NJS-Eu),并与小分子稀土配合物NJS-Eu性能对比,TG分析可知大分子有机配体比小分子有机配体配位效率高,荧光光谱分析知p-NJSEu的荧光强度约为Eu Cl3的5倍。将稀土配合物掺杂入EVA胶膜作为太阳能电池封装材料,结果表明,大分子稀土配合物掺杂比小分子稀土配合物掺杂对EVA胶膜在可见光透过率的影响小,且大分子稀土配合物在胶膜中分散性较好,并与基质有良好的相容性,当p-NJS-Eu添加0.2%,EVA胶膜的光电转换效率增加了0.88%。In this paper,polymeric acids macromolecular complexes poly 6-（ acryloyloxy）- 2- carboxylic acid Eu（ p-NJS- Eu） have been prepared,and compared with small molecules complexes NJS- Eu. TG analysis show that the macromolecular ligands have higher coordination ability than small molecule ligands,the fluorescence emission intensity of the complex p- NJS- Eu is far more stronger,about 5 times higher than that of EuCl_3. The complexes doped- EVA film as solar cell encapsulation material was measured by test instrument of photoelectric conversion efficiency. The results show that doping of macromolecular rare earth complexes has less impact on visible light transmittance of EVA film than that of doping of small molecule rare earth complexes,p- NJS- Eu has better dispersion and compatibility in the EVA matrix. When the p- NJS-Eu is 0. 2%,EVA film photoelectric conversion efficiency is increased by 0. 88%.
