Abstract

Abstract: Three-dimensional macroporous fluorine-doped tin oxide ( p -FTO) films were successfully deposited using commercial ink of FTO powder and SnCl2 salt via Dr. Blade method. Various features of p -FTO thin films were studied as a function of the ink composition and sintering temperature. The morphological studies corroborated formation of porous, uniform, and crack-free FTO films after annealing at 300 °C for 10 min in air. X-ray diffraction pattern demonstrated development of highly crystalline FTO films. The lowest sheet resistance of 47 Ω/□ was obtained for the p -FTO film with a thickness of 21 μm. The capacitance of thin p -FTO films was investigated using a three-electrode system and the results illustrated that the p -FTO films had an ideal electric double-layer capacitive behavior over a wide range of scan rate potential. Electro-deposition of manganese oxide on porous FTO film surface enhanced the real capacitance from 5 to 36 mF/cm 2 .
