Abstract
In this study, we report synthesis and growth of rutile-anatase TiO2 thin film on fluorine-doped tin oxide (FTO) glass by a two-step hydrothermal method. The effects of additional treatments (i.e., TiCl4 post-treatment and seed layer formation were also studied. Photocurrent-voltage (I-V) measurement of rutile-anatase TiO2 thin film was performed under 1.5 G light illumination. Photovoltaic performance was investigated by incident photon-to-electron conversion efficiency (IPCE), electrochemical impedance spectroscopy (EIS), intensity-modulated photocurrent/ photovoltage spectroscopy (IMVS/IMPS) and open-circuit photovoltage decay (OCVD).
