title: A single cis-2 regioisomer of ethylene-tethered indene dimer-fullerene adduct as an electron-acceptor in polymer solar cells.
abstract: A pure cis-2 isomer of indene dimer-based fullerene bis-adduct has been synthesized, isolated and applied to bulk heterojunction solar cells for the first time. The device based on the cis-2 isomer and poly(3-hexylthiophene) exhibited a power conversion efficiency of 2.8%, which is higher than those of the reference devices.
