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...

In this current research, we described an enhanced power conversion efficiency of dye sensitized solar cell (DSSC) and fabricated through Few Layered Graphene (FLG)/CuO nanocomposite synthesized by ultrasonic assisted synthesis (UAS) by varying of FLG (1, 2 and 3 wt%) ratio. The FLG/CuOnanocomposites characteristic features understood through various microscopic techniques such as FE-SEM and HR...

The substitution of iodide electrolytes with cobalt ones has led to the current champion laboratory efficiencies for dye-sensitized solar cells (DSSCs). However, unlike with organic dyes, this strategy does not work with classical ruthenium dyes. Therefore, we compare DSSCs sensitized with a popular Ru dye (N719) using both types of electrolytes by exploring the electron dynamics occurring from...

Introduction Motivated by continuously growing global energy demands and the depletion of readily accessible fossil fuels; the search for alternative energy sources, particularly renewable solar energy, has become vital. Despite the clear advantages associated with the adoption of solar cells, they need to be cost-effective and priced competitively in comparison to conventional energy resources...

In this study, an intriguing difference caused by structural isomerization based on anthracene and phenanthrene stilbazole type ancillary ligands in Ru(ii) sensitizers for dye sensitized solar cells (DSCs) has been investigated using femtosecond transient absorption spectroscopy. Both anthracene and phenanthrene based sensitizers HD-7 and HD-8, respectively, resulted in a similar extinction coe...

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...

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...
