High-sensitivity deep shortwave infrared organic photodetectors enabled by selenium-integrated quinoidal molecular semiconductor

Developing organic photodetectors (OPDs) that can detect in deep shortwave infrared (deep-SWIR) region (1.2–1.6 μm) is technologically important. Yet, the performance of the state-of-the-art deep-SWIR OPDs remains substantially limited. Herein, we report a selenium-integrated qui...

Ordered J‐Aggregation Directed by Inner Alkyl Chains Enables Additive‐ and Annealing‐Free Organic Solar Cells With 20.73% Efficiency

ABSTRACT Molecular aggregation behavior of non‐fullerene acceptors (NFAs) plays a pivotal role in the photovoltaic performance of organic solar cells (OSCs). In Y‐series NFAs, excessive H‐like core contacts may increase packing disorder, while terminal group‐mediated J‐like inter...
