Recent research is focused on few layered graphene (FLG) with various metal oxides (MOs) as (MOs; CeO2, CuO, SnO2, CdO, ZnO, and TiO2) nanocomposite materials are alternatives to critically important in the fabrication of solar cell devices. In this work, FLG different MOs nanocomposites were prepared by a novel eco-friendly viable ultrasonic assisted route (UAR). The FLG/MO performed character...

Silver (Ag) doped ZnO (SZO) nanomaterials were synthesized by hydrothermal method and characterized. nanostructures with 0.0%, 0.5%, 1%, 1.5mol% Ag. These obtained SZO analyzed using X-ray diffraction measurement (XRD), Scanning Electron Microscopy (SEM), Energy Dissipative spectroscopy (EDX). The structural analysis confirmed the formation of samples having a hexagonal wurtzite phase. morpholo...

By replacing volatile and flammable organic-based electrolytes with gel electrolytes, dye-sensitized solar cells (DSSCs) may be a viable more practical alternative to other clean energy sources. Although they present promising alternative, still have some drawbacks for applications, such as low ionic conductivity infusion difficulties into the pores of working electrode. Here, we introduce new ...

Ammonia is commonly synthesized through the Haber-Bosch process, which produces large amounts of CO2 emissions as it carried out at extreme temperatures and pressures. An alternative technology needed to synthesize ammonia consumes less energy environmentally friendly. In this research, a Dye-Sensitized Solar Cell Photoelectrochemical tandem system (DSSC-PEC) was developed for nitrogen reductio...

Ammonia (NH3) is one of the important chemicals for human life. The demand ammonia expected to increase every year. Conventionally, fixation process N2 produce NH3 in industrial sector carried out through Haber−Bosch process, which requires extreme temperature and pressure conditions that consume a high amount energy emit considerable CO2. Therefore, it necessary develop alternative technology ...

Dye-sensitized solar cells are currently under intense academic and industrial investigation, owing to their great potential to serve as a low-cost alternative to existing photovoltaic technologies. This paper puts forward a method, which adopts heterocyclic substituted triarylamine units as electronic donor moieties, to design triarylamine dyes for efficient dye-sensitized solar cells. Three n...

An efficient synthetic protocol to functionalize the cyanoacrylic acid anchoring group of commercially available MK-2 dye with a highly water-stable hydroxamate anchoring group is described. Extensive characterization of this hydroxamate-modified dye (MK-2HA) reveals that the modification does not affect its favorable optoelectronic properties. Dye-sensitized solar cells (DSSCs) prepared with t...

Terpyridine and quaterpyridine-based complexes allow wide light harvesting of the solar spectrum. Terpyridines, with respect to bipyridines, allow for achieving metal-complexes with lower band gaps in the metal-to-ligand transition (MLCT), thus providing a better absorption at lower energy wavelengths resulting in an enhancement of the solar light-harvesting ability. Despite the wider absorptio...
