Negligible amounts of QBT induce striking modifications in the P3HT lamellar stacking direction, forming both densely packed and non-densely packed P3HT chains. The former reduce the charge carrier recombination rate, enabling an increased fill factor and short-circuit device photocurrent. | URI: | https://hdl.handle.net/20.500.14279/9132 | ISSN: | 20507488 | Rights: | © The Royal Society of Chemistry 2016. | Type: | Article | Affiliation : | Fondazione Istituto Italiano di Tecnologia Politecnico di Milano INAF-Osservatorio Astronomico di Brera Uppsala University Umeå University University of Nottingham Cyprus University of Technology |
