|Title:||A strong regioregularity effect in self-organizing conjugated polymer films and high-efficiency polythiophene: fullerene solar cells||Authors:||Choulis, Stelios A.
|Keywords:||Polymers;Fullerenes;Nanostructured materials;Plastic films;Solar cells||Issue Date:||2006||Publisher:||Nature||Source:||Nature materials, 2006, Volume 5, Issue 3, Pages 197-203||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||URI:||http://ktisis.cut.ac.cy/handle/10488/7613||ISSN:||1476-1122 (print)
