“…As has been investigated by XRD study, this can be attributed to the crystallinity of SnO 2 phase where the higher crystallinity is directly proportional to the easier electron transfer, and thus higher conductivity. This is in agreement with previous work done by Tatar and Duzgun (2012). In our present work, it is also confirmed that the addition of fluorine doping has resulted in the decrease in electrical resistivity significantly.…”

Fluorine-doped tin oxide (FTO) is one of the conductive glasses that have strategic functions in various important applications, including dye-sensitized solar cell (DSSC). In the current work, the effects of deposition time (5, 10, 20, 30, and 40 minutes) upon the fabrication process of FTO thin film using spray pyrolysis technique with modified ultrasonic nebulizer has been studied in regard to its microstructural, optical, crystallinity, and resistivity characteristics. The variation was also performed by comparing the pure tin chloride precursor and the solution that was doped with fluor (F) at 2 wt% in order to see the doping effect on the properties of thin film. The thin films were characterized using x-ray diffraction (XRD), scanning electron microscope (SEM), ultraviolet-visible (UV-Vis) spectroscopy, and digital multimeter. On the basis of current investigation, it has been found that the best FTO was obtained through the pyrolysis technique of 20-minute deposition time, providing optical transmittance of 74%, a band gap energy (E g ) of 3.85 eV and sheet resistance (R s ) of 7.99 Ω/sq. The fabricated FTO in the present work is promising for further development as conducting glass for dye-sensitized solar cell (DSSC).

“…This can be attributed to the value of the measured crystallinity layer as shown in Figure 5. The crystallinity is directly proportional to the conductivity, which is supported by research conducted by Tatar and Duzgun (2012) stating that the higher the value of crystallinity, the lower the resistivity values. Thus, higher substrate temperatures result in lower resistivity values, producing conductive properties.…”

Transparent conducting oxide (TCO) glasses play an important role in various technology, including dye sensitized solar cells. One of the most commonly used glass is indium tin oxide (ITO) glass, which is expensive. Therefore, the main purpose of this research was to determine if ITO glass can be replaced with fluorine-doped tin oxide (FTO) glass, which is easier and more economic to manufacture. For this purpose, a tin chloride dehydrate (SnCl 2. 2H 2 O) precursor was doped with ammonium fluoride (NH 4 F) using a sol-gel method and spray pyrolysis technique to investigate the fabrication process for conductive glass. NH 4 F was doped at a ratio of 2 wt% in the SnCl 2. 2H 2 O precursor at varying deposition times (10, 20, and 30 minutes) and substrate temperatures (250, 300, and 350°C). The results revealed that longer deposition times created thicker glass layers with reduced electrical resistivity. The highest optical transmittance was 75.5% and the lowest resistivity was 3.3210 -5 Ω.cm, obtained from FTO glass subjected to a 20-minute deposition time at deposition temperature of 300 o C.

“…The sheet resistances of above prepared FTO thin films were studied using the four point probe technique [13,14]. We observed that as the low volume of solution was sprayed into the glass substrate, the sheet resistance wasfound to be high due to only athin layer of FTO deposited.…”
