High Performance Ternary Organic Solar Cells due to Favored Interfacial Connection by a Non-Fullerene Electron Acceptor with Cross-Like Molecular Geometry
Abstract
The non-fullerene electron acceptor, TPB, exhibits a unique cross-like molecular geometry which helps it to stay preferentially at the interfaces between PTB7-Th and PC71BM, when it is used as the third component in ternary OPV cells. The four PDI units connected to TPB's core provide multiple contact points between PTB7-Th and PC71BM phases, thus facilitating interfacial charge extraction and improving the overall PCE to 10.6% from 9.8% after 10% TPB was added as the third component. Here, this article describes detailed experimental results and a model to explain these observations.
