Precursor‐Level Molecular Coupling Enables High‐Fill‐Factor Wide‐Bandgap Perovskite Solar Cells and 29.63% All‐Perovskite Tandems

ABSTRACT Wide‐bandgap (WBG) perovskites with a ∼1.78 eV bandgap are essential for monolithic all‐perovskite tandem cells, yet their efficiency and stability are limited by complex precursor chemistry, uncontrolled crystallization, defect formation, and photoinduced halide segrega...

Regulating H‐Aggregation via a Thiazole‐Modified Acceptor‐Based Packing Reshaper Toward Highly Efficient and Stable Organic Solar Cells

ABSTRACT Organic solar cells (OSCs) based on non‐fullerene acceptors have achieved power conversion efficiencies (PCEs) exceeding 20%. However, their long‐term stability remains limited by uncontrolled molecular aggregation and morphological degradation in bulk heterojunction (BH...
