Revisiting Open‐Circuit Voltage in Heterojunction‐Scarce Organic Solar Cells

Electron, EarlyView.
This work establishes an analytic framework based on the interplay between the composition‐driven density of states and geminate recombination for understanding the open‐circuit voltage of bulk heterojunction‐reduced organic solar cells. ABSTRACT Organic solar cells (OSCs) have reached power conversion efficiencies (PCEs) above 21%, yet their market ...

Thermally activated delayed fluorescence exciplex sensitizers with fast reverse intersystem crossing for improving efficiency stability of organic light‐emitting diodes based on multi‐resonance emitters

FlexMat, EarlyView.
Two exciplex emitters are constructed based on a host‐guest doping strategy, and their exciton dynamics processes are investigated in depth. High‐performance OLEDs are fabricated by employing these exciplexes as emitters or sensitizers, providing excellent electroluminescence efficiencies and low efficiency roll‐offs.

Flexible white thermally activated delayed fluorescence polymer with alkyl spacer and side‐chain encapsulation for efficient solution‐processed white organic light‐emitting diodes

FlexMat, EarlyView.
A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).
