Title: | Improved performance of polymer/ TiO2 nanorod bulk heterojunction photovoltaic devices by interface modification | Authors: | Lin Y.-Y. Chu T.-H. Chen C.-W. WEI-FANG SU CHUN-WEI CHEN |
Issue Date: | 2008 | Journal Volume: | 92 | Journal Issue: | 5 | Source: | Applied Physics Letters | Abstract: | In this article, the polymer photovoltaic devices based on the poly(3-hexylthiophene)/ TiO2 nanorods hybrid material is present. An enhancement in the device performance can be achieved by removing or replacing the insulating surfactant on the TiO2 nanorod surface with a more conductive ligand, which can play the role to assist charge separation efficiency or also to prevent from back recombination, giving a large improvement in the short circuit current and fill factor. The relatively high power conversion efficiency of 1.7% under simulated AM 1.5 illumination (100 mW cm2) can be achieved, providing a route for fabricating low-cost, environmentally friendly polymer photovoltaic devices by all-solution processes. © 2008 American Institute of Physics. |
