Major Field of Science: | Engineering and Technology | Field Category: | Mechanical Engineering | Keywords: | Polymers;Fullerenes;Nanostructured materials;Plastic films;Solar cells | Issue Date: | 5-Feb-2006 | Source: | Nature materials, 2006, vol. 5, no. 3, pp. 197-203 | Volume: | 5 | Issue: | 3 | Start page: | 197 | End page: | 203 | Journal: | Nature Materials | Abstract: | The influence of polymer regioregularity (RR) on the molecular nanostructure, and on the resulting material properties and device performance was analyzed. Annealed blend films show increased α regardless of RR, that indicates improved charge-carrier diffusion. It was found that the highest device efficiencies will be achieved with the highest RR P3HT. It was also found that the dark-current density of as-fabricated devices made with pristine P3HT increases with the RR of P3HT in the higher voltage regime | ISSN: | 1476-4660 | DOI: | 10.1038/nmat1574 | Rights: | © Nature | Type: | Article | Affiliation : | Imperial College London Pusan National University Pohang University of Science and Technology Merck Chemicals |
