由导电聚合物和纳米半导体颗粒组成的复合材料因其独特的电子和光学性质而在科学和技术上具有吸引力。这些特性被发现依赖于嵌入颗粒的大小。在这项研究中，这种与聚苯胺(PANI)导电聚合物的纳米复合材料被报道。结果表明，硫化镉和硫化铜纳米晶可以成功地包覆到聚苯胺基质中，并且可以通过调节添加剂的浓度来控制其粒径。制备了具有不同US浓度的CDS/PANI体系的光伏器件，并对其性能进行了研究。这些器件的短路电流(I-SC)和开路电压(V-OC)随聚合物基质中硫化镉浓度的增加而增大。纳米晶体的使用允许通过改变纳米晶体的大小、浓度和材料来控制器件的性能。(C)2002 Elsevier Science B.V.保留所有权利。
Composites consisting of conducting polymers and nanosized semiconductor particles are scientifically and technologically attractive because of their unique electronic and optical properties. These properties were found to depend on the size of the embedded particles. In this study such nanocomposites with polyaniline (PANI) conducting polymers are reported. The results have shown that CdS and Cu2S nanocrystals can be successfully incorporated into a polyaniline matrix and their particle sizes can be controlled by adjusting the concentration of the additives. Photovoltaic devices with CdS/PANI systems of various US concentrations were fabricated and their performance were investigated. The short circuit current (I-SC) and open circuit voltage (V-OC) of these devices were found to increase with the concentration of CdS in the polymer matrix. The use of nanocrystals allows great flexibility in controlling the performance of the devices by changing the size, concentration and the material of the nanocrystals. (C) 2002 Elsevier Science B.V.
