While self-assembled material based inverted perovskite solar cells have surpassed power conversion efficiencies of 26%, enhancing their performance in large-area configurations remains a significant challenge. In this work, we report hole-selective layer 4-(7H-dibenzo[c,g]carbazol-7-yl)phenyl)phosphonic acid, with π-expanded conjugation. The enhanced intermolecular π–π interactions facilitate the self-assembly acid molecules to form an ordered bilayer hydrophilic surface, which passivates...
Production of functionally graded materials (FGMs, i.e., a gradual transition from one material to another) and components is challenging using conventional manufacturing techniques. Additive (AM) provides new opportunity for producing FGMs. However, current metal AM technologies including powder-bed fusion are limited single or vertical FGM parts, different composition in layers but not within the same layer, situ changing challenging. In this paper, we demonstrate fabrication horizontal 3D...
Strain sensors for smart wearable textiles have recently attracted great attention due to their potential in the healthcare applications, specifically, functions track heartbeat, pulse signals, and movements of limbs joints. Traditional methods typically require complicated procedures including dip-coating different solutions prepare sensing fibers before weaving into fabrics. In this study, we used an ultraviolet picosecond laser directly induce graphene on polyimide (PI) fabric produce a...
This article reviews various dopant‐free hole transporting materials (HTMs) used in perovskite solar cells (PSCs) three main categories including inorganic, polymeric, and small molecule HTMs. PSCs have undergone rapid progress, achieving power conversion efficiencies (PCEs) above 22%. With their low production cost high efficiencies, are considered promising next‐generation cell technology. In all developed architectures for PSCs, planar mesoscopic with conventional inverted structures,...

The commercialization of lithium-sulfur (Li-S) batteries faces several challenges, including poor conductivity, unexpected volume expansion, and continuous sulfur loss from the cathode due to redox shuttling.
