Two kind of CuO-ZnO nanocomposite working electrodes were synthesized by sol-gel technology and applied in dye-sensitized solar cells (DSSCs). Their characteristics were studied by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and UV-Vis diffuse reflectance spectrum (DRS). CuO-ZnO nanocomposite thin films were prepared doctor blade technique on the fluorine-doped tin oxide (FTO) and used as working electrodes in dye sensitized solar cells (DSSC). Their photovoltaic behavior were compared with standard using D35 dye and an electrolyte containing Co(bpy)32, Co(pby)33, LiClO4, and 4-tert-butylpyridine (TBP). The ranges of short-circuit current (JSC) from 0.18 to 0.21 (mA/cm(2)), open-circuit voltage (VOC) from 0.24 to 0.55V, and fill factor from 0.34 to 0.39 were obtained for the DSSCs made using the working electrodes. The efficiency of the working electrodes after the addition of TBL was more than doubled. The light scattering and carrier transport properties of these composites promote the performance of dye-sensitized solar cells (DSSCs).
两种氧化铜-氧化锌纳米复合材料通过溶胶-凝胶技术合成，并应用于染料敏化太阳能电池（DSSC）中。通过场发射扫描电子显微镜（FESEM）、X 射线衍射（XRD）和紫外可见漫反射光谱（DRS）研究了它们的特性。通过刮刀技术将氧化铜-氧化锌纳米复合材料薄膜制备在掺氟氧化锡（FTO）上，并用作染料敏化太阳能电池（DSSC）中的工作电极。将其与使用 D35 染料和含有[Co（bpy）3]（PF6）2、[Co（pby）3]（PF6）3、LiClO4 和 4-叔丁基吡啶（TBP）的电解质的标准进行了比较。使用工作电极制备的 DSSC 的短路电流（JSC）范围为 0.18 至 0.21mA/cm2，开路电压（VOC）范围为 0.24 至 0.55V，填充因子范围为 0.34 至 0.39。添加 TBL 后，工作电极的效率增加了一倍以上。这些复合材料的光散射和载流子传输性能提高了染料敏化太阳能电池（DSSC）的性能。
