Enhanced <i>ε</i> <sub>r</sub> / <i>L</i> <sub>D</sub> and improved acceptor crystal growth enable all-polymer solar cells with outstanding efficiency, stability, and processability from a chlorinated-dimer diluent additive
A chlorinated dimer acceptor (D-SeV-Cl) was designed as a diluent additive for PM6:PYT. Blade-coated all-PSCs using a green solvent achieved a device efficiency PCE exceeding 20%with excellent stability and processability.
