1,2,4-Benzotriazine-Based Asymmetric Acceptors with Dual π-Conjugation Extension Achieve 20.74% Efficiency in Organic Solar Cells.

Core-asymmetric acceptors, which combine the advantages of electron-deficient cores and molecular asymmetry, represent a promising yet underexplored design strategy for organic solar cells. Herein, we designed and synthesized two asymmetric 1,2,4-benzotriazine-based acceptors, H-Th and H-Th-FN, both featuring a chlorin...

Flexible Linker Engineering of Dimeric Acceptors Enables Synergistic Modulation of Dielectric Constant and Spatial Conjugation for Organic Solar Cells Exceeding 20% Efficiency.

The performance of organic solar cells (OSCs) is predominantly constrained by the low dielectric constants of organic semiconductors, which limit exciton dissociation and exacerbate charge recombination. In particular, dimeric acceptor molecules (DMAs) typically suffer from insufficient short-circuit current density an...
