Soluble Dicyanodistyrylbenzene‐Based Non‐Fullerene Electron Acceptors with Optimized Aggregation Behavior for High‐Efficiency Organic Solar Cells

Abstract

A new class of small molecules based on dicyanodistyrylbenzene combined with naphthalimide is developed for use as non-fullerene electron acceptors in bulk heterojunction organic solar cells. The optical, electrochemical, and film formation characteristics of the new materials are found to be suitable for preparing solution-processed devices. Solar cells prepared with poly(3-hexylthiophene) (P3HT) as a donor material exhibit a maximum power conversion efficiency of 2.71%.
