Title: Tailoring nanoscale morphology of polymer: Fullerene blends using electrostatic field

Abstract

We study the effect of electrostatic field (E-field) on the solidification of poly(3-hexylthiophene-2, 5-diyl) (P3HT):[6,6]-phenyl-C61-butyric acid methyl ester (PC60BM) bulk heterojunction (BHJ) in order to tailor the nanomorphology in polymer/fullerene blends. In addition to control; wet P3HT:PC60BM thin films were exposed to E-field of Van de Graaff (VDG) generator at three different directions—horizontal (H), tilted (T), and vertical (V)—relative to the plane of the substrate. Surface and bulk characterizations of the field-treated BHJs affirmed that fullerene molecules can easily penetrate the spaghetti-like P3HT and move up and down following the E-field. We achieved favorable morphologies with efficient charge separation, transport, and collection by using the E-field treatment,. We improve; (1) the hole mobility values up to 19.4 × 10–4 ± 1.6 × 10–4 cm2 V–1 s–1 and (2) the power conversion efficiency (PCE) of conventional and inverted OPVs up to 2.58 ± 0.02% and 4.1 ± 0.40%, respectively. This E-field approach can serve as a new morphology-tuning technique, which is generally applicable to other polymer–fullerene systems.
