Abstract We investigate the photovoltaic properties of hybrid organic solar cell based on the blend of poly[2-methoxy-5-(2_-ethylhexoxy-1,4-phenylenevinylene) (MEH-PPV), C60 and titanium dioxide (TiO2) nanotubes. In comparison of the composite devices with different TiO2:[MEH-PPV +C60] weight ratios of 1wt.% (D1-1), 2wt.% (D1-2), 3wt.% (D1-3), 5wt.% (D1-4), 10wt.% (D1-5) and 20wt.% (D1-6), it is found that the device D1-3 exhibits the best performance. The
conversion efficiency is improved by a factor of 3 compared with the MEH-PPV:C60 device.
