Abstract
Transparent conducting oxide (TCO) glasses play important role in many recent modern technologies including its application for dye sensitized solar cell. One of the most commonly used is indium tin oxide (ITO), however its price is rather expensive. Therefore, the main purpose of the current research is aimed at replacing ITO with fluorine-doped tin oxide (FTO) which is easier and more economic for fabrication. For this purpose, tin chloride dehydrate (SnCl2.2H2O) precursor doped with ammonium fluoride (NH4F) source by using sol-gel method and spray pyrolisis technique can be considered as a new breakthrough in the making of conductive glass. In this work, the ammonium floride was doped at a ratio of 2 wt persen to tin chloride precursor with variations of deposition time (10,20 and 30 minutes) and substrate temperature (250, 300 and 350 °C) upon spray pyrolysis technique. The results showed that the longer deposition time the thicker glass layer is, providing smaller resistivity. In this study, the highest transmittance of 75.5 persen and the lowest resistivity of 3,32 x 10-5 Ω.cm resitivitas were obtained from the glass subjected to 20 minutes deposition time and 300 oC substrate heating during the process.
