Photoconductivity of Nanocomposite MEH-PPV: TiO₂ Thin Films

Abstract:

The photoconductivity of a nanocomposite MEH-PPV:TiO₂ thin film is investigated. The nanocomposite MEH-PPV:TiO₂ thin film was deposited on a glass substrate by spin coating technique. The composition of the TiO₂ powder was varied from 5 wt% to 20 wt% (with 5 wt% interval). The concentration of the MEH-PPV is given by 1 mg/1 ml. The current voltage characteristics were measured in dark and under illumination. The photoconductivity showed increment in value as the composition of the TiO₂ is raised in the polymer based solution. The absorption showed augmentation as the amount of TiO₂ is increased. The escalation of the current voltage is then supported by the results of surface morphology.
