MORPHOLOGY AND RESISTIVITY VALUE OF FLOURINE-DOPED TIN OXIDE (FTO) USING INDONESIAN LOCAL DIMETHYLTIN DICHLORIIDE (DTMC) PRECURSORS

Transparent Conductive Oxide (TCO) is the main component for solar cell fabrication. One of promising types TCO fluorine-doped tin oxide (FTO). The method used in depositing conductive layer FTO spray pyrolysis with an ultrasonic nebulizer. precursor a local Indonesian product, dimethyl dichloride (DMTC), doping ammonium fluoride (NH4F). variable that this study were variations deposition time (5. 10. 15. 20, and 25 minutes) fixed substrate temperature at 300°C (un-doped, 2 wt.% doped 8 doped) to see effect adding F solution. resistivity value 5. 20 minute (2 0.218x100; 0.449x10-1; 1,567x10-2; 0.676x10-2 0.377x10-2 Ω.cm. For wt% 0.883x10-2; 0.377x10-2; 0.506x10-3 There decreasing trend values obtained along increase addition obtain better properties. grain size will increasing doping. optimum was Ω.cm, minutes
