Various tandem cell configurations have been reported for highly efficient and spontaneous hydrogen production from photoelectrochemical solar water splitting. However, there is a contradiction between two main requirements of a front photoelectrode in a tandem cell configuration, namely, high transparency and high photocurrent density. Here we demonstrate a simple yet highly effective method t...

this research reports a facile ultrasonic approach for the synthesis of iron vanadate (fevo4) nanoparticles with the aid of ammonium metavanadate (nh4vo3) and fe(no3)3.9h2o as the starting reagents without adding external surfactant, capping agent or template in an aqueous solution. furthermore, to examine the solar cell application of as-synthesized iron vanadate (fevo4) nanoparticles, fto/tio...

Introduction: Accessibility to safe drinking water is an important human health issue, so water reuse and water resources management are critical in arid parts of developing  regions. This study aimed to investigate the use of a combined simple designed solar geyser/photocell for drinking water disinfection. Materials and Methods: In this study, a solar geyser with a simple design was combined...

Thermal modelling and optimal design of a solar absorption cooling system are presented, and hourly analysis is performed over the period of a year. Three design parameters are considered, then the Real Parameter Genetic Algorithm (RPGA) is applied to obtain the minimum total annual cost. The optimization results show that the solar cooling optimum configuration needs 1630 square meter collecto...

The significant market growth of stationary electrical energy storage systems both for private and commercial applications has raised the question battery lifetime under practical operation conditions. Here, we present a study two 8 kWh lithium-ion (LIB) systems, each equipped with 14 lithium iron phosphate/graphite (LFP) single cells in different cell configurations. One system was based on st...
