摘要

Here we demonstrated an approach to increase performance of P3HT:TiO 2 solar cell either by electron deficient boron or electron rich bismuth doping into TiO 2 nanorods. The B doping increases the absorption, crystallinity and electron mobility of TiO 2 nanorods. The Bi-doped TiO 2 has higher J sc as compared with B-doped TiO 2 , mainly due to the improvement of electron density and increased absorption of TiO 2 nanorods. The devices were fabricated from TiO 2 nanorods being surface modified by organic dye W-4. The dye facilitates the bandgap alignment and compatibility between TiO 2 and P3HT. The power conversion efficiency of solar cell has been increased by 1.33 times and 1.30 times for Bi-doped TiO 2 and B-doped TiO 2 , respectively, as compared with that of as-synthesized TiO 2 . The results suggest the optical and electronic properties of TiO 2 can be tuned by various dopants to enhance the device performance.
