A Tetraphenylethylene Core‐Based 3D Structure Small Molecular Acceptor Enabling Efficient Non‐Fullerene Organic Solar Cells. (27th November 2014) - Liu, Yuhang
Abstract A tetraphenylethylene core‐based small molecular acceptor with a unique 3D molecular structure is developed. Bulk‐heterojunction blend films with a small feature size (≈20 nm) are obtained, which lead to non‐fullerene organic solar cells (OSCs) with 5.5% power conversion efficiency. The work provides a new molecular design approach to efficient non‐fullerene OSCs based on 3D‐structured small‐molecule acceptors.
