Abstract in another language

Abstract Light-induced X,W-band Electron Spin Resonance (LESR) study of double-crystalline donor-acceptor block copolymers (BCPs) comprised of poly-3-hexylthiophene as the donor and poly-perylene bisimide acrylate as the acceptor segments is presented. It is suggested that, while the intrinsic light-induced charge separation efficiency in the {BCPs} registered by {LESR} could be more efficient than in bulk heterojunction solar cells based on the P3HT/PCBM blends, the photovoltaic performance of the {BCPs} is limited significantly by the incorrect orientation of crystalline π-stack morphology of (poly-perylene bisimide acrylate) domains.
