TiO2 (anatase) and Fe2O3 (hematite) nanopowders were mixed in the weight ratio 1:1.5 and 1:2 and homogenized in a planetary ball mill for an hour. After that pastes were prepared of the two powder mixtures, organic vehicle and glass frit. The pastes were screen printed on FTO coated glass substrates and sintered at 800°C/10 minutes. Formation of monoclinic pseudobrookite was confirmed by XRD analysis of the thick film samples. The thick film crystal structure and optical properties were observed by SEM and UV/Vis spectroscopy. Current-voltage analysis was performed on a sandwich structure formed of thick film and two conductive FTO layers (bottom and top).
