This paper reports the performance of alizarin based SnO₂ dye-sensitized solar cells. A novel template assisted method has been applied for the preparation of tin oxide nanoparticles. For the first time, onion (Allium cepa) was used as a template for the synthesis of tin oxide nanostructures at different pH values. Tin oxide nanostructures were used for the photoanode preparation. A sandwich cell was prepared by using the dye soaked SnO₂ film as a photoanode and platinum as a counter electrode. The structural, morphological and optical properties of the nanoparticles were studied using powder X-ray diffraction (XRD), Scanning Electron microscope (SEM), Photoluminescence (PL), Attenuated Total Reflectance (ATR) spectra and UV–visible spectroscopic techniques. Current–voltage (I–V) characteristics have been measured using electrochemical workstation under the presence of solar illumination. Characteristic parameters of the fabricated cell were determined on the basis of the measured I–V curves.

本文报道了基于茜素的SnO ₂染料敏化太阳能电池的性能。一种新颖的模板辅助方法已被用于制备氧化锡纳米颗粒。首次将洋葱（洋葱洋葱头）用作模板，用于在不同pH值下合成氧化锡纳米结构。氧化锡纳米结构用于光阳极制备。使用浸有染料的SnO ₂制备三明治电池薄膜作为光阳极，铂作为对电极。使用粉末X射线衍射（XRD），扫描电子显微镜（SEM），光致发光（PL），衰减全反射（ATR）光谱和紫外可见光谱技术研究了纳米颗粒的结构，形态和光学性质。电流-电压（IV）特性已在太阳光照射下使用电化学工作站进行了测量。根据测得的I–V曲线确定制造电池的特征参数。
