Abstract:

In living organisms the photosynthesis involves the absorption of light by the light-harvesting (LH) antenna complexes. By mimicking the photosynthesis process the artificial photonic device composed of bio-molecular hetero structure is developed. The proposed photonic device is composed of Chl a, Chl b, phycoerythrin and phycocyanin. To fabricate the highly ordered structure of biomolecules, the deposition of ordered Chl a/Chl b molecules onto solid substrates was done by the Langmuir-Blodgett (LB) technique, and the self-assembly technique was used for the deposition of phycocyanin molecule.

Tetrabenzoporphyrin films on indium-tin-oxide electrodes were prepared by continuous spin-coating of indium-tin-oxide electrodes with a soluble precursor, tetrabicyclo[2.2.2]octadiene-fused porphyrin, and subsequent thermal conversion of the precursor to tetrabenzoporphyrin by annealing the modified electrodes. When the tetrabenzoporhyrin-modified indium-tin-oxide working electrode was irradiated in a three-electrode system, using Pt as a counter electrode and Ag / Ag + as a reference electrode in the presence of hexyl viologen as an electron acceptor, a cathodic photocurrent was observed.

AbstractWe have successfully demonstrated plasmon-enhanced photocurrent generation using gold nanoparticle-loaded titanium dioxide single-crystal (TiO2) photoelectrodes with visible-light irradiation. Water molecules serve as an electron source in photocurrent generation, and oxygen evolution occurs due to water oxidation from a gold nanostructured TiO2 photoelectrode as a half reaction of water splitting. On the basis of this property, the photocurrent generation system was applied to the plasmon-induced water-splitting system using both sides of the same strontium titanate (SrTiO3) single-cr

The photogalvanic effect was studied in a photogalvanic cell containing Ethylene-diaminetetra-acetic acid as reductant and methylene blue and thionine as photosensitizers. The photopotential and photocurrent generated were 752.0 mV and 90.0 μA, respectively. The observed conversion efficiency was 0.43 per cent and the maximum output of cell was 67.68 μW. The photogalvanic cell can be used for 30 min in the dark. The effects of different parameters on electrical output of the cell were observed, and a mechanism for the generation of photocurrent in photogalvanic cells has also been proposed.

Transmission electron microscopy studies show that these NPs decorate the MWCNTs on topological defect sites.

However, a simpler device architecture based on a single organic semiconductor (SS-OPV) offers several advantages: it obviates the need to control the highly system-dependent nanoscale BHJ morphology, and therefore, would allow the use of broader range of organic semiconductors. Unfortunately, the photocurrent in standard SS-OPV devices is typically very low, which generally is attributed to inefficient charge

Abstract:

Structural health monitoring systems are required for detecting damage in structures so as to facilitate their timely maintenance and repair and to prevent catastrophic structural failure. To date, a variety of different sensor platforms (e.g., piezoelectric materials, fiber optics, and wireless sensors) have been proposed for SHM. However, they still suffer from high energy demand, large form factors, and durability issues, particularly when applied for monitoring space structures and reusable spacecraft. In a previous study, a bio-inspired and photocurrent-based strain sensor has been develo

Abstract:

The method of chemical deposition of monocrystalline bismuth thioiodide BiSI needles with a high quantum efficiency of photocurrent generation (up to 55 %) in aqueous solutions of electrolytes has been developed. It was revealed that the introduction of sulfide and iodide anions into the electrolyte solution leads to an increase of the absolute photocurrent values, as well as the presence of sulfide ions causes the significant (about 0.5 V) shift of BiSI bands energy towards more negative electrode potentials. The observed effect is of interest for increasing the photovoltage of solar cells ba

Abstract:

Semiconductormetal nanocomposites provide a simple and convenient way to tailor the properties of photocatalysts. Modification of semiconductor surface improves charge separation and promotes interfacial charge-transfer processes in nanocomposite systems. Charge accumulation in the metal layer results in Fermi-level equilibration raising the quasi-Fermi level of the composite close to the conduction band level of the oxide semiconductor. Phototransformations of such compositesincluding morphological changes, interfacial charge-transfer processes and photocurrent generation of TiO2-capped gold

Abstract:

A photoconductive fractal antenna significantly improves the performance of photomixing-based continuous wave (CW) terahertz (THz) systems. An analysis has been carried out for the generation of CW-THz radiation by photomixer photoconductive antenna technique. To increase the active area for generation and hence the THz radiation power we used interdigitated electrodes that are coupled with a fractal tree antenna. In this paper, both semiconductor and electromagnetic problems are considered. Here, photomixer devices with Thue-Morse fractal tree antennas in two configurations (narrow and wide)

Abstract:

The present study reports the fabrication of CdSe quantum dot (QD)-sensitized photocathodes on NiO-coated indium tin oxide (ITO) electrodes and their H2-generating ability upon light irradiation. A well-established spin-coating method was used to deposit CdSe QD stock solution onto the surface of NiO/ITO electrodes, thereby leading to the construction of various CdSe QD-sensitized photocathodes. The present report includes the construction of rainbow photocathodes by spin-coating different-sized QDs in a sequentially layered manner, thereby creating an energetically favorable gradient for char

AbstractChip-scale microspectrometers, operational across the visible to long-wave infrared spectral region will enable many remote sensing spectroscopy applications in a variety of fields including consumer electronics, process control in manufacturing, as well as environmental and agricultural monitoring. The low weight and small device footprint of such spectrometers could allow for integration into handheld, unattended vehicles or wearable-electronics based systems. This review will focus on recent developments in nanophotonic microspectrometer designs, which fall into two design categorie
