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
