Summary: Researchers have discovered that lattice distortion in iodide/bromide mixed perovskites can suppress phase segregation, leading to increased ion-migration energy barrier. By using an approximately 2.0-electron-volt rubidium/caesium mixed-cation inorganic perovskite with large lattice distortion, they achieved an efficiency of 24.3% in all-perovskite triple-junction solar cells. This is the first reported certified efficiency for perovskite-based triple-junction solar cells.

Summary: The study demonstrates an effective graded bulk-heterojunction (G-BHJ) strategy using nonhalogenated solvent sequential deposition for nonfullerene acceptor (NFA) organic solar cells, achieving outstanding power conversion efficiency (PCE) of 17.48%. Advanced techniques such as depth-profiling X-ray photoelectron spectroscopy (DP-XPS) and angle-dependent grazing incidence X-ray diffraction (GI-XRD) enable visualization of morphology and crystallinity gradient distributions, leading to high PCEs of thick OSCs. The use of nonhalogenated solvent in G-BHJ OSC via open-air blade coating achieves a record 16.77% PCE by suppressing unfavorable phase separation in bulk-heterojunction. Overall, the G-BHJ strategy shows great promise for highly efficient, eco-friendly, and scalable organic solar cells.

Summary: In this study, a full-solution-processed device framework for semi-transparent intrinsically stretchable organic photovoltaics (is-OPVs) was reported. The device utilized a ferroconcrete-like composite of AZO@silver nanowires (AgNWs)@AZO as the back stretchable transparent electrode (STE), providing a 3D long-range pathway for efficient charge transport and collection while enhancing interfacial stability. The is-OPV achieved a record power conversion efficiency (PCE) of 10.90% by employing thermoplastic polyurethane-embedded AgNWs as the front STE. Mechanical robustness was demonstrated with 76.5% retained initial PCE after 500 cycles of 10% stretch-release. This work lays the foundation for the development of semi-transparent is-OPVs for wearable applications and skin-like electronics.
