Boosting Conversion Efficiency in Zn3P2/InP Solar Cells Via Nanoscale Junction Engineering
Advanced Functional Materials, EarlyView.This study demonstrates the efficacy of selective area epitaxy (SAE) in enhancing the conversion efficiency of a Zn3P2${\rm Zn}_3{\rm P}_2$/InP heterojunction solar cell. The impact of the SAE pattern dimensions on the performance parameters is investigated. Small size opening limits Jsc because of current crowding whereas large size opening limits Voc

Advanced Functional Materials, EarlyView.We demonstrate the direct integration of CsPbBr3 perovskite nanocrystals (PNCs) into optoelectronic devices without post‐synthetic ligand exchange. This is achieved by synthesizing PNCs stabilized by strong‐binding‐energy oleylammonium–bromide pairs instead of oleate ligands. The resultant low ligand density and minimized surface defects enhance charge

Fullerene‐Mediated Iodine Immobilization at Buried Interfaces in Sn–Pb Perovskite Solar Cells
Advanced Functional Materials, EarlyView.Indene‐C60 bisadduct (ICBA) accumulates at the buried interface of inverted tin‐lead perovskite solar cells, limiting undesired electron extraction while maintaining efficient hole transport. ICBA simultaneously scavenges molecular iodine, mitigating Sn2+ oxidation and interfacial recombination. This coupled electronic‐chemical regulation delivers 22.7%

Thermoresponsive Soft and Self‐Anchoring Cuff Electrode for Chronic Peripheral Interfaces
Advanced Functional Materials, EarlyView.A novel thermoresponsive, soft and self‐anchoring (TSSA) cuff electrode utilizing shape memory polymers achieves autonomous, sutureless peripheral nerve fixation. Driven by thermally induced pre‐strain and tissue adhesion, the device self‐closes and softens at body temperature, successfully minimizing mechanical mismatch. This adaptive platform ensures

Advanced Functional Materials, EarlyView.A field‐driven transition from chiral stripes to an achiral fan state is observed in a tetragonal magnet and linked to a temperature‐dependent rotation of the effective Dzyaloshinskii–Moriya interaction axis. This interplay generates pronounced in‐plane anisotropy and provides a new route for controlling chiral spin textures in noncentrosymmetric ...
