| 摘 要： | 利用溶剂热法制备了新型的还原石墨烯-CuInS2(rGO-CuInS2)复合材料. 通过X射线衍射(XRD)、 Raman光谱、 紫外-可见吸收光谱(UV-Vis)、 荧光光谱(PL)、 透射电子显微镜(TEM)及高分辨透射电子显微镜(HRTEM)等对所得材料的结构进行了表征. 结果表明, rGO-CuInS2复合材料中CuInS2的尺寸为3~5 nm. 将不同组成的rGO-CuInS2复合材料应用于杂化太阳能电池, 结果发现, 与还原石墨烯(rGO)的能量转换效率相比, rGO-CuInS2复合材料的能量转换效率得到明显提高, 通过对不同组成的rGO-CuInS2复合材料制备的太阳能电池器件进行分析, 得到性能达到最高效率(1.10%)时复合物的最佳组成.

| Abstract: | A new type of reduced graphene oxide-CuInS2(rGO-CuInS2) composite was successfully synthesized via solvothermal method. The structure of composite was characterized by X-ray diffraction(XRD), Raman, UV-Vis(UV-Vis), photoluminescence(PL) spectra, transmission electron microscopy(TEM) and high-resolution transmission electron microscopy(HRTEM). The results show that CuInS2 quantum dots, with a size of 3—5 nm, disperses uniformly on the surface of graphene. In addition, the growth mechanism of the composite was also investigated. And, the rGO-CuInS2 composites with different rGO/CuInS2 mass ratio were applied in hybrid photovoltaic device. Compared with the power conversion efficiency(η) of the device based on reduced graphene oxide(rGO), the device based on rGO-CuInS2 composites exhibit higher performance with the highest η of 1.10% when the composite mass ratio is 0.5:1. |
