Increasing prerequisite for sustainable energy storage and conversion technologies has necessitated exploration of advanced materials with improved properties. Here, we present the synthesis characterization ZnO nanoparticles (NPs), ZnO/NiO, ZnO/Co3O4 ZnO/NiO/Co3O4 NCs as promising bi-functional dye-sensitized solar cell (DSSC) electrochemical applications. A facile chemical co-precipitation approach was followed to pure NPs, NCs. The structural morphological analyses revealed successful...

Abstract Semiconducting materials are pivotal in various fields, such as solar cells, LEDs, photovoltaic etc. A nature‐friendly chitosan is a good film‐forming, water‐soluble polymer that modified to small band‐gap for optoelectronic applications. Choline chloride:ethylene glycol:glycerin (1:1:1) deep eutectic solvent (DES)‐modified activated carbon incorporated into the matric and this composite fabricated thin films via spin coating methodology. The obtained subjected multiple studies...

Abstract Reactant solubility, which dictates achievable concentrations, and the stability of reaction intermediates (excited states), solvents modulate potential energy landscape influence rates. Consequently, solvent selection is pivotal in optimizing process productivity, economic feasibility, environmental footprint. At present, organic synthesis pivots around idea sustainability. In particular, PEG‐400, a popular phase transfer catalyst, considered greener as it can be reused several...
