基于量子点材料的特殊物理性能和量子点聚合物复合材料高的光电转换性能,本文在MOPPV溶液中制备了粒度可控、结晶性好、颗粒尺寸约为3.75 nm的ZnSe量子点材料,最终获得不同质量比的MOPPV/ZnSe复合材料.分别使用X射线衍射、透射电子显微镜、紫外可见吸收光谱等研究其特性结果表明MOPPV与ZnSe量子点可以有效地复合且发生光诱导电荷转移;通过对MOPPV、ZnSe和MOPPV/ZnSe复合材料太阳电池性能的研究发现,与MOPPV和ZnSe单体相比复合材料光伏特性呈现增加的趋势,并且复合材料光电性能随着ZnSe量子点材料质量浓度的增加呈现先增大后减小的现象,当MOPPV和ZnSe的质量比为1:1时,其转换效率最大,开路电压为0.516 V,短路电流为2.018 mA,填充因子为25.53%,转换效率为0.167%.

Based on some special physical properties of solar cells prepared from quantum dots polymeric materials, which have high photoelectric conversion performance, we use MOPPV solution for obtaining controllable grain sizes, good crystallinity, with a particle size of about 3.75 nm ZnSe quantum dot polymer composite materials, and different quality ratios of the composites. We also use XRD, TEM, UV-vis absorption spectra to study the characterizstics of the materials. The result shows that MOPPV and ZnSe quantum dots have effectively combined together and photoinduced charge transfer. Through the study of MOPPV, ZnSe, and MOPPV/ZnSe composite materal solar cell performance, we found that the composites exhibit an increasing trend compared with MOPPV, ZnSe monomer material photovoltaic characteristics, and the photoelectric properties of the composites showed an increase at first and then reduced with increasing quality of ZnSe quantum dots;when the ratio of MOPPV and the quality of the ZnSe is 1:1, its conversion efficiency reaches a maximum, The Voc, Isc, FF and conversion efficiency of solar cells were 0.516 V, 2.018 mA, 25.53%, and 0.167%.
