Ultra-thin organic photovoltaic with a record power conversion efficiency of 18.46%, a highest power density of 40.31 W g⁻¹ and up-scalability is demonstrated, via precisely optimizing the optoelectronic properties of silver nanowire transparent electrode.

The effective combination of machine learning and design of experiment methods screen the preparation conditions and design fabrication parameters in all-small-molecule organic solar cells, and the experimental device with SQ:ITIC is verfied the screen result.

A reconfigurable FTEG with a Lego structure is proposed for TE chips composed of all-inorganic MXene/Bi₂Te₃ composite films. In this composite film, the MXene acts as a conductive bridge to optimize the TE performance. Our FTEG demonstrates a mechanical plug-in design, achieving an open-circuit voltage of up to 100 mV and an output power of 7.12 μW at a temperature difference of approximately 45 K.

Inspired by an insect visual system, bioinspired photonic waveguide pixelated color convertors (BPW-PCCs) are demonstrated to realize directional excitation and outcoupling. By this strategy, ultrathin BPW-PCCs with 4.4-fold enhanced photoluminescence intensity have been demonstrated in micro-light-emitting diode devices and achieved a record-high luminous efficacy of 1600 lm W⁻¹ mm⁻¹, opening a new avenue for efficient miniaturized displays.

In this review, Liu et al. provide a systematic summary of the challenges hindering the development of electroconductive hydrogel-based bioelectronics. They also present several methods to address these challenges. The authors discuss the applications of electroconductive hydrogels in healthcare monitoring, disease treatment, and human–machine interfaces. Finally, they offer future perspectives on this flexible materials in bioelectronics.

Novel bimetallic ions modified 2-MeIm/PPy/GO nanosheets were successfully prepared, and Co²⁺-Ruⁿ⁺/(2-MeIm)x@PPy/GO (n = 0, 4) exhibited the excellent stability for supercapacitors.
