Transparent conducting oxide (TCO) films of titania doped with vanadium (V), niobium (Nb) and tantalum(Ta) are obtained by aqueous Chemical Solution Deposition (CSD). The effect of the dopant on the crystallization and microstructure of the resulting films is examined by means of X-ray diffraction and electron microscopy. During annealing of the thin films, in-situ characterization of the crystal structure and sheet resistance is carried out. Niobium doped anatase films, obtained after annealing in forming gas, show a resistivity of 0,28 Ohm cm, which is the lowest resistivity reported for a solution deposited anatase-based TCO so far. Here, we demonstrate that aqueous CSD may provide a strategy for scalable TCO production in the future. ; SoPPoM program of the Strategisch Initiatief Materialen (SIM), Interreg Vlaanderen Nederland, Solar flare (grant number IVA-VLANED-1.59); FWO (grant number G 023709) ; transparent conducting oxide; ceramic; TiO2; solution based synthesis; sol-gel chemistry
