The Effect of Substrate Heating Temperature upon Spray Pyrolysis Process on the Morphological and Functional Properties of Fluorine Tin Oxide Conducting Glass

Transparent conductive oxide (TCO) is one of the main components in the dye sensitized solar cell (DSSC), adevice which is developed as one of renewable energy sources that has high potential to substitute fossil fuel. Among allTCO glasses, fluorine-doped tin oxide (FTO) has the biggest potential to be developed. The purpose of this research isaimed at finding an optimum substrate temperature during spray pyrolysis process in order to obtain FTO substrates withthe desired characteristics. For this purpose, soda lime glasses were deposited with a mixture of tin and fluorine dopingprecursors using a special modified ultrasonic nebulizer with a variation in substrate heating temperature of 250, 300, 350,400, and 450oC. All the fabricated samples were characterized by using x-ray diffraction (XRD), UV-Vis spectrometry,scanning electron microscope (SEM), and digital multimeter. On the basis of investigation, the best result was obtained inthe substrate heated at 300 oC, providing an electrical resistance of 8 ohm/sq and optical transmittance of 74 persen. This researchcreates a chance for the next fabrication of TCO glass with desired properties using simple-low cost facilities. AIP Conference Proceedings 1826, 020003(1-9) (2017)
