Extensive research in nanotechnology has been conducted to investigate new behaviours
and properties of materials with nanoscale dimensions. ZnO NPs owing to their distinct …

Zinc oxide (ZnO) is the closest alternative to TiO 2 as the semiconductor material in a dye-
sensitized solar cell (DSSC). This is to be attributed to the facts that both TiO 2 and ZnO have …

Materials with hierarchical porosity and structures have been heavily involved in newly
developed energy storage and conversion systems. Because of meticulous design and …

ZnO was one of the first metal oxides used in dye-sensitized solar cells (DSCs). It exhibits a
unique combination of potentially interesting properties such as high bulk electron mobility …

Nanotechnology opens a door to tailing materials and creating various nanostructures for
use in dye-sensitized solar cells. This review classifies the nanostructures into (1) …

ZnO nanorods doped with different concentrations of Ag and Nd (1–7%) were synthesized
by hydrothermal method. In this article we describe the synthesis, characterization and …

Indium doped zinc oxide nanoparticles (NPs) with various indium concentrations were
prepared by cost effective and low temperature aqueous solution method. The structure and …

Spherical particles are of great interest because they are a thermodynamically favorable
state in terms of surface energy. Recent work has fully demonstrated their potential to obtain …

Zinc oxide (ZnO) hierarchical structures (HSs) have recently demonstrated notable
photochemical and photovoltaic performances attributed to their nano/micro combined …

Zinc oxide-cobalt oxide nanocomposites (ZnO–Co 3 O 4 NCs) with diverse concentrations
(0.03, 0.06, 0.09 and 0.12 M) of Co 2+ ions were synthesized by a simple chemical co …
