Phosphor‐Sensitized Ternary Organic Solar Cells Achieving 18.6% PCE via Ir(III)‐Mediated Triplet Energy Transfer and Non‐Radiative Recombination Suppression

ABSTRACT Phosphor‐sensitized organic solar cells (PS‐OSCs) enhance exciton utilization and suppress non‐radiative recombination by incorporating triplet‐enabled sensitizers into bulk‐heterojunction blends. Here, we report a green‐emitting Ir‐3 complex as a multifunctional phospho...

Structure‐Guided Balancing of Ambipolar Transport Enables Symmetric Switching in Heterojunction Bilayer Organic Transistor Inverters

ABSTRACT High inverter performance in ambipolar organic electronics requires balanced channel strengths rather than maximized single‐carrier mobility. Here, we demonstrate symmetric switching through balanced ambipolar transport in vertically stacked pentacene/ N , N ′‐ditridecyl...
