The structure of ITO/P3HT/TiO

/TiO
x
nanoparticle/alheterojunction organic solar cell was fabricated by the specific film technology. Titanium oxide layers were made by using different TiO
x
precursors. The effect of the TiO
x
layer on the performance of the solar cells was studied. We found that the devices made by the TiO
x
layers mixed with organics result in effective open-circuit voltage but correspondingly lower short-circuit current. The effection of low temperature annealing and thickness optimization of TiO
x
layers on the performance of devices was studied. Applying room temperature technology to prepare TiO
x
precursor solution not only gets the excellent results but also simplifies the process.
