A Double-Cable Polymer Acceptor Enables 20% Efficiency in Ternary Organic Solar Cells

Key Points

This research aims to explore the efficiency of a new double-cable polymer acceptor in ternary organic solar cells.
Developed a double-cable polymer acceptor (PYT-N) with a Y-series backbone and pendant NDI units
Incorporated PYT-N into D18:eC9 blends
Measured power conversion efficiency (PCE) of the resulting ternary devices
Achieved a power conversion efficiency (PCE) of 20% in the ternary solar cells
Demonstrated improved performance compared to traditional binary blends

Abstract

We report a double-cable polymer acceptor (PYT-N) featuring a Y-series backbone with pendant NDI units. When incorporated as a third component in D18:eC9 blends, the ternary device achieves a PCE...
