To maximize light coupling into the active layer, plasmonic nanostructures have been incorporated both layers of organic solar cells (OSCs) and perovskite (PSCs) with aim increasing absorption, but reports shown controversial results in electrical characteristics. In this work, we introduce a core-bishell concept to build nanoparticles (NPs) metal-inorganic semiconductor-organic semiconductor nanostructure. Specifically, Ag NPs were decorated titania/benzoic-acid-fullerene bishell...
We propose an efficient multiband absorber comprised of a truncated, one-dimensional periodic metal-dielectric photonic crystal and reflective substrate. The substrate is essentially optically thick metallic film. Such planar device easier to fabricate compared absorbers with complicated shapes. For four-unit cell device, all four the absorption peaks can be optimized efficiencies higher than 95 percent. Moreover, those are insensitive polarization incident angle. influences geometrical...
With the rapid progression of industrialization, water pollution has emerged as an increasingly critical issue, especially due to release organic dyes such methylene blue (MB), which poses serious threats both environment and human health. Developing efficient photocatalysts effectively degrade these pollutants is therefore paramount importance.

Fast and sensitive photodetectors (PDs) with broadband spectral responses are crucial in numerous fields, including image sensing, optical communication, biochemical applications. While organic PDs offer responses, their response speed is typically limited to the microsecond range. This study demonstrates a sensitive, ultrafast PD broad by combining 2D perovskite layer an heterojunction of poly[(4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b;4,5-b']...

The Al O bottom passivation can reduce the pinhole defects in film suppress trap‐related recombination loss, bringing forward much reduced dark current increased...
Late transition metal catalysts represent a significant class of olefin polymerization that have played an essential role in advancing the polyolefin industry owing to their highly tunable ligands and low oxophilicity. A key feature for design late lies steric bulk o-aryl substituents. Bulky 8-arylnaphthylamines emerged as promising aniline candidate conducting high-performance by introducing axially hindrance around center. This review focuses on (Ni, Pd, Fe) derived from...

Solution-processed all-inorganic lead halide perovskites are widely utilized to develop photodetectors (PDs) due their excellent optoelectronic properties. The low-cost titanium nitride (TiN) electrode not only has better corrosion resistance than Ag but also possesses good conductivity comparable Au electrode, the utilization of TiN in perovskite PDs been rarely reported.

Abstract Silicon carbide (SiC) semiconductors with a wide bandgap have attracted much attention because they can endure harsh environments and high temperatures. SiC photodetectors based on conventional principles usually detect ultraviolet (UV) light without the ability to discriminate wavelength.

Hot-electron photodetectors (HEPDs) are triggering a strong surge of interest in applications image sensors and optics communication, since they can realize photoelectric responses when the incident photon energy is lower than bandwidth semiconductor. In traditional HEPD systems, metal layers dressed with regular gratings, which only excite plasmonic resonance over narrow bandwidth, limiting hot-electron effect. To break this limitation, hybrid nanostructures should be applied HEPDs. Here,...
