Gallium-doped ZnO (GZO) thin films on glass, which can be used as transparent electrodes, were prepared using a spin coating technique. Thermal analysis and Fourier-transform infrared spectroscopy of the dried precursor solution Zn acetate Ga nitrate dissolved in ethanol with diethanolamine confirmed decomposition organic components upon heating formation at 450 °C. The fired 600 °C oxygen air,...

We report on top-illuminated, fluorine tin oxide/indium tin oxide-free (FTO/ITO-free), dye-sensitized solar cells (DSCs) using room-temperature-processed ZnO layers on metal substrates as the working electrodes and Pt-coated Ga-doped ZnO layers (GZO) as the counter electrodes. These top-illuminated DSCs with GZO render comparable efficiency to those employing commercial FTO counter electrodes. ...

The addition of suitable metallic dopants into the indium or zinc oxide matrix is essential to obtain transparent conducting (TCO) thin films for high-performance optoelectronics devices. However, scarcity one major challenges common use doped tin (ITO) as a TCO material future state-of-the-art To overcome challenge, used an alternative traditional ITO and retains both high transparency electri...

Zinc oxide (ZnO) is a potential thermoelectric material with good chemical and thermal stability as well an excellent Seebeck coefficient. However, the extremely low carrier concentration brings poor electrical transport properties. Although Gallium (Ga) doping could increase of ZnO film, its performance still limited due to deteriorated coefficient enhanced conductivity. Interface engineering ...

Purpose: Solar energy is necessary for our global ecosystem. In certain times and parts of the world, heat generated from Sun becomes uncomfortable us we need to use additional cool down Sun. This usage detrimental environment due generation air pollution natural resources. The purpose this paper investigate prevention undesired by using reflective coating materials.
 Methodology: study, l...
