Abstract

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.
