Development of high-efficiency organic solar cells processed from green solvents
Abstract
The Gao group at Link?ping University, Sweden, proposes a new research effort to be carried out in concert with theoretical studies performed by the Bredas group at The University of Arizona that aims: (i) to advance significantly our understanding of how thefunctionalization of non-fullerene acceptors (NFAs) with oligo(ethylene glycol) (OEG) chains affects the film morphologies of the neat acceptors and of their blends with polymer donors; (ii) to evaluate the impact of the OEG side-chains on the optical, electronic, and electrical properties of neat NFA films and of their blends; and (iii) to understand why the nature of the (green) solvent hardly impacts these properties. Overall, by combining the results of the advanced measurements and computational results, we will provide: (i) a thorough description of the effects that OEG side chains have on the materials properties; (ii) an understanding of the minimal impact that the nature of (green) solvent has on these properties; and (iii) guidelines to design new materials for efficient organic solar cells (OSCs) fabricated via processing with environmentally friendly green solvents. The overall goal is to develop new active-layer materials for large-scale, high-, and stable OSCs fabricated by using environmentally friendly green solvents, opening the way to light-weight, flexible, and shock-resistant mobile power generation during Navy and Marine Corps operations.
