Organic solar cells (OSCs) is promising candidates for flexible and portable device due to their many attractive characteristics such as light-weight and solution-processability. Recently, Outstanding power conversion efficiency (PCE) over 16% has been achieved in bulk heterojunction (BHJ) OSCs consisted of donor (D) and acceptor (A).[1] Single molecular donor–acceptor (D-A) conjugates where the D and A moieties are integrated by a covalent linkage in a single molecule have been reported for its potential as an alternative photovoltaic material.[2] In order to suppress large phase separation in BHJ films, SCOSCs can be a promising strategy. By Incorporating a SC molecule system in OSCs, efficient charge generation in a single molecules and enhanced morphological stability are expected. In this study, we designed and synthesized a new C70-based SC molecule by incorporating different length of alky chain to optimize the morphology and charge transfer characteristics. The detailed synthesis of molecule, optical, morphological, electrochemical and photovoltaic properties will be presented.
