Summary: This study investigates the mechanical behavior and structural stability of a highly stretchable woven fabric containing tri-component elastic-conductive composite yarns (t-ECCYs). The study finds that the woven fabric with t-ECCYs has a denser and tighter surface, which enables its weft elastic stretchability over 40% and demonstrates excellent mechanical robustness. The study also proposes a modified standard solid model that accurately replicates the tensile characteristics during stretch. Additionally, the fabric shows nearly unchanged structural stability after cyclic expansion and washing-drying cycles.

Summary: Organic semiconductor single crystal materials have great potential in high-performance optoelectronic devices due to their ordered structure, low defects, and high carrier mobility. However, controlling the nucleation location in crystal growth methods is challenging, hindering the manufacturing of organic crystal devices. This study demonstrated in situ nucleation of perylene crystals using femtosecond laser-induced cavitation, showing that the crystallization is mainly caused by aggregation of laser cavitation bubbles induced by multiphoton absorption. This strategy enables the application of organic single crystals in optoelectronic devices.

Summary: In this study, highly flexible and transparent OLEDs (TrOLEDs) with ultrathin metal films as both anode and cathode were successfully fabricated, providing high transparency and stretchability. The TrOLEDs exhibited excellent transmittance of 73% at 550 nm and nearly Lambertian emission characteristics at a wide angle of view. The symmetric electroluminescent properties of the anode and cathode were important for dual-side display. Two-dimensional TrOLEDs with random wrinkles showed 50% stretchability and retained 80% initial luminance after 200 stretching cycles. The effect of wrinkles on the transmittance of TrOLEDs was investigated, contributing to the development of TrOLEDs in the display industries.

Summary: Flexible perovskite solar cells (FPSCs) have attracted attention for their potential applications in next generation electronics, but the current transparent conductive electrodes (TCEs) hinder their flexible performance. In this study, a hybrid electrode (PUA/AgNWs/PH1000) consisting of a thin layer of silver nanowires (AgNWs) on a flexible substrate (PUA) modified with a conductive layer (PH1000) was proposed. This electrode showed high optical transmittance, electrical conductivity, and mechanical flexibility. When used in FPSCs, the ITO-free devices with the hybrid electrode exhibited desired flexibility and mechanical stability, retaining 77.4% of their initial power conversion efficiency after 10,000 bending cycles with a bending radius of 5 mm.
