Abstract

This paper focuses on fabricating ZnO-based dye-sensitized solar cells (DSSCs) utilizing three types of dyes derived from Rhus, Linaria and Punica flowers. The ZnO thin films were prepared on tin-doped indium oxide (ITO) coated glass substrates at 70 °C according to successive ionic layer adsorption and reaction (SILAR) method. Organic sensitizers were extracted from Rhus, Linaria and Punica flowers using ethanol solvent. The fabricated solar cells were characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), UV-vis spectroscopy and fourier transformation infrared (FTIR) techniques. The maximum photovoltaic values were obtained from ZnO/Linaria-based DSSC which exhibits current density (J sc ) of 0.328 mA/cm−2, open-circuit voltage (V oc ) of 1 V, fill factor (FF) of 64% and energy conversion efficiency (η) of 0.210% having the minimum thickness of 1.381 μm among all the DSSCs studied in this work, though. Energy dispersive X-ray spectrometry (EDS) analysis indicated that the weight contribution of oxygen for Linaria DSSC is 53.30%, and this value is higher than Rhus and Punica DSSCs. The results suggest that Linaria dye-sensitizer can be a good candidate for minimizing the thickness of the photoelectrode films and improving the performance of DSSCs.

利用红属植物、林荫属植物和Punica制备zno基染料敏化太阳能电池

本文主要研究了利用从树属、Linaria和Punica花中提取的三种染料制备zno基染料敏化太阳能电池(DSSCs)。采用连续离子层吸附反应(SILAR)方法，在70℃的温度下，在锡掺杂氧化铟(ITO)镀膜玻璃基底上制备了ZnO薄膜。采用乙醇溶剂从大梁花、Linaria花和Punica花中提取有机增敏剂。利用x射线衍射(XRD)、扫描电镜(SEM)、能量色散x射线能谱(EDS)、紫外可见光谱(UV-vis)和傅里叶变换红外(FTIR)等技术对制备的太阳能电池进行了表征。ZnO/ linaria基DSSC的光伏值最高，电流密度为0.328 mA/cm−2，开路电压为1 V，填充系数为64%，能量转换效率为0.210%，最小厚度为1.381 μm。能量色散x射线光谱(EDS)分析表明，氧对Linaria DSSC的质量贡献为53.30%，高于rthus和Punica DSSCs。结果表明，Linaria染料敏化剂可以减小光电极膜的厚度，提高DSSCs的性能。
