ABSTRACT All‐polymer solar cells (all‐PSCs) combine the synthetic tunability of non‐fullerene acceptor systems with intrinsic mechanical and thermal robustness of polymer active layers, yet their performance remains limited by pronounced bimolecular recombination, leading to insufficient fill factors (FFs) compared to...

Ordered molecular packing is considered essential for optimizing organic optoelectronic properties. However, despite disordered morphologies with nanoscale phase‐separated structure, bulk heterojunction (BHJ) organic photovoltaics (OPVs) have recently achieved remarkable efficiencies exceeding 20% with Y6‐based non...
While highly ordered self-assembled monolayers (SAMs) are critically important for inverted perovskite solar cells (i-PSCs), precise control over molecular orientation remains a persistent challenge, hindering the concurrent achievement of high efficiency and long-term stability. To address this issue, we unveil that t...
