%X Photovoltaic properties of photodiodes based on nano-TiO2 and poly[2-methoxy,5-(2¡ä-ethlhexyloxy)-p-phenylenevinylene] (MEH-PPV) composites are investigated. By comparing composite devices with the same weight of TiO2 (nanoparticles and nanotubes):MEH-PPV, it was found that the device with TiO2 nanotubes exhibited better performance. By further optimizing the weight radio of TiO2 nanotubes: MEH-PPV, we gained the device with a short circuit current density of 9.27 ¦ÌA/cm2 with a light intensity of 16.7 mW/cm2 at the 500 nm wavelength, the highest open-circuit voltage of 1.1 V, and a photosensitivity of 332 at reverse bias of  0.6 V. The photosensitivity is improved by a factor of 33 compared with the undoped MEH-PPV device.
