Donor‐Selective NiCo‐LDH Templating Directs Polymer Assembly for Enhanced Exciton Transport in Efficient Organic Solar Cells

ABSTRACT Organic solar cells (OSCs) have achieved remarkable progress, yet improving exciton utilization in polymer donors remains challenging due to their intrinsically limited exciton diffusion length ( L D ). Here, we report a donor‐selective templating strategy based on few‐l...

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...
