【摘要】：通过利用一种生活中常见的垃圾-鸡蛋壳膜(Chicken Eggshell Membranes,ESM)作为原料,以简单的液相浸渍和炭化的方法制备了负载铜硫铟(CuInS2)纳米晶的碳化鸡蛋壳膜(Carbonized Chicken Eggshell Membranes,CESM),并应用于染料敏化太阳能电池的对电极。利用场发射扫描电镜、X-衍射、透射电镜和激光拉曼等相关测试表征了所制备CuInS2-CESM复合材料的形貌和结构,结果表明其呈现由碳纳米纤维组成的三维多孔网络结构,并且碳纳米纤维上均匀地分布着平均尺寸约为25nm的黄铜矿CuInS2纳米晶。太阳能电池光电性能测试表明,CESMCuInS2对电极比CESM对电极显示了更佳的短路电流密度(J_(sc)=12.48mA/cm~2)、开路电压(V_(oc)=0.78V)和光电转换效率(η=5.79%),并且接近于标准Pt对电极的光电性能。
[Abstract]:The carbonated egg shell film (Carbonized Chicken Eggshell Membranes,CESM) loaded with copper indium sulfide (CuInS2) nanocrystals was prepared by a simple liquid phase impregnation and carbonization method using a common garbage egg shell membrane (Chicken Eggshell Membranes,ESM) as raw material. And applied to the opposite electrode of dye sensitized solar cell. The morphology and structure of CuInS2-CESM composites were characterized by field emission scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM) and laser Raman spectroscopy. And the average size of chalcopyrite CuInS2 nanocrystals about 25nm is distributed uniformly on the carbon nanofibers. The photovoltaic properties of the solar cell show that the CESMCuInS2 pair electrode shows better short circuit current density (J _ (sc) = 12.48mA/cm~2), open circuit voltage (V _ (oc) = 0.78 V) and photoelectric conversion efficiency (畏 = 5.79%) than the CESM pair electrode. And it is close to the photoelectric performance of the standard Pt pair electrode.
