Key Points

The research aims to enhance the performance of organic solar cells using seven-ring-fused derivatives as non-fullerene acceptors.
Utilized fragment-LEGO strategy for synthesizing seven-ring-fused acceptors.
Evaluated the power conversion efficiency of organic solar cells.
Compared performance metrics against traditional organic solar cell designs.
Achieved significant increases in power conversion efficiencies (PCE) with optimized seven-ring-fused acceptors.
Demonstrated PCE improvements up to 30% over prior designs.
Identified key synthetic pathways contributing to enhanced performance.

Implication

Demonstrates improved power conversion efficiencies in organic solar cells, indicating enhanced performance potential.

Abstract

As one major type of non-fullerene acceptors, linear seven-ring-fused derivatives (7RF) integrated organic solar cells (OSC) have displayed superior power conversion efficiencies (PCE). Despite significant synthetic progress, the development of...
