dc.description.abstract | Polymer solar cells have been spotlighted due to their potential for low-cost manufacturing but their efficiency is still less than required for commercial application as lightweight/flexible modules. Forming a dipole layer at the electron-collecting interface has been suggested as one of the more attractive approaches for efficiency enhancement. However, only a few dipole layer material types have been reported so far, including only one non-ionic (charge neutral) polymer. Here we show that a further neutral polymer, namely poly(2-ethyl-2-oxazoline) (PEOz) can be successfully used as a dipole layer. Inclusion of a PEOz layer, in particular with a nanodot morphology, increases the effective work function at the electron-collecting interface within inverted solar cells and thermal annealing of PEOz layer leads to a state-of-The-Art 10.74% efficiency for single-stack bulk heterojunction blend structures comprising poly[4,8-bis(5-(2- ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b0]dithiophene-Alt-3-fluorothieno[3,4-b]thiophene- 2-carboxylate] as donor and [6,6]-phenyl-C71-butyric acid methyl ester as acceptor. © 2015 MacMillan Publishers Limited.
