In this paper we report synthesis and analysis of low cost screen printed coating of TiO 2 in the form of thick film fabricated on glass substrate followed by annealing at 350 °C. The film has been characterized by x-ray diffraction (XRD), Scanning electron microscope (SEM) with energy dispersive x-ray (EDX), UV-visible and Fourier-transform infrared(FTIR) spectroscopy and current-voltage (I-V) measurement via two probe. The XRD analysis showed that the prepared thick film has crystal structure of anatase phase with preferred orientation of (1 0 1)plane. The SEM image identified porous nature of film while EDX spectra revealed the presence of titanium and oxygen atoms in the film. The FTIR spectrum displayed the strong presence of TiO 2 . DC electrical conductivity measurements revealed that electrical conductivity increases on increasing temperature which confirms semiconducting behaviour.

丝网印刷的TiO 2膜：光伏应用的候选材料

在本文中，我们报告了在玻璃基板上制造厚膜形式的TiO 2低成本丝网印刷涂层的合成和分析，然后在350°C进行退火。通过X射线衍射（XRD），具有能量色散X射线（EDX）的扫描电子显微镜（SEM），紫外可见光和傅立叶变换红外（FTIR）光谱以及电流-电压（IV）测量来表征该膜通过两个探针。XRD分析表明，所制备的厚膜具有锐钛矿相的晶体结构，其优选取向为（1 0 1）面。SEM图像确定了膜的多孔性，而EDX光谱表明膜中存在钛和氧原子。FTIR光谱显示出TiO 2的强烈存在。
