制备了由具有各种封端配体的硒化镉纳米晶体和聚3-己基噻吩混合制成的光伏器件。研究了封端配体和退火条件的影响。我们发现封端配体决定形态/相分离。我们的研究结果表明，在 105 至 122 摄氏度之间的温度下进行退火可以产生优化的器件。我们还报告了 CdSe/P3HT 混合器件在 AM1.51D 照明下的效率为 1.8%。由 Elsevier B.V. 出版
Photovoltaic devices made from blended cadmium selenide nanocrystals with various capping ligands and poly-3-hexylthiophene were prepared. The effects of capping ligands and annealing conditions were investigated. We find that capping ligands determine morphology/phase separation. Our findings suggest that annealing at temperatures between 105 and 122 degrees C yield optimized devices. We also report CdSe/P3HT blended devices with an efficiency of 1.8% under illumination by AM1.51D. Published by Elsevier B.V.
