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...

Balancing Injection and Short‐Channel Effects in Organic Permeable Base Transistors via Thickness Scaling

ABSTRACT Organic permeable base transistors (OPBTs) have attracted attention as vertical organic transistors that achieve high current density at a low operating voltage. While reducing organic semiconductor thicknesses is a common approach to improve performance in OPBTs, its su...
