Widebandgap (WBG) perovskites are critical for highefficiency tandem solar cells but suffer from rapid crystallization, photoinduced halide segregation, and interfacial losses. We introduce methyl 2(4,4,5,5tetramethyl1,3,2dioxaborolan2yl)1Hindole7carboxylate (MHIC) as a multifunctional modulator for 1.68 eV WBG per...
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 segregation. Here, we report 4-(3-Carbamimidoylguanidino...

Organic solar cells (OSCs) hold promise for building-integrated and wearable photovoltaics, yet excessive H-aggregation of non-fullerene acceptors (NFAs) quenches luminescence and lowers the photoluminescence quantum yield (PLQY), limiting further efficiency gains. Here, we introduce NTCl-4F, a molecular H-aggregation...

Fibrillar networks formed during solution processing play a key role in the high performance of modern organic solar cells (OSCs). Yet their formation is intrinsically non-equilibrium and largely stochastic, leading to discontinuous domains and mismatched donor/acceptor interfaces that limit charge transport. Here, we...
