Influence of Spin Coating Speed on Optical Properties of Spin-Coated TiO2 Thin Films

S. Abdullahi, M. Momoh & A. U. Moreh · Journal of Materials Science Research and Reviews · 2023

In this work, nanocrystalline TiO2 thin films have been prepared by the sol-gel spin coating method at different spin speeds. X-ray diffraction (XRD), Scanning electron microscopy, and UV–vis spectroscopy were used to investigate the structural and optical properties of the depos...

Numerical Study of Transparent Conductive Oxide (TCO) Layer on the Performance of Methyl-Ammonium Tin Iodide (CH3NH3SnI3) Perovskite Solar Cells Using SCAPS

Faruk Sani & S. Abdullahi · Asian Journal of Research and Reviews in Physics · 2021

Substrates used in perovskite solar cells as front contact are usually transparent conductive oxide (TCO) to allow light to pass through the device. The dominating TCO employed in perovskite solar cells are indium-doped tin oxide (ITO) and fluorine-doped tin oxide (FTO). However,...
