Effect of Thiourea Concentration on Structural, Optical and Electrical Properties of Spray – pyrolysed Copper – Zinc – Tin – Sulphide Films
Copper-zinc-tin-sulphide (CZTS) thin films were prepared by spray pyrolysis technique using copper chloride, zinc chloride, tin (IV) chloride and thiourea as copper, zinc, tin and sulphur source respectively. In this ...
Red Spinach Dye Extracts as Photosensitizer in Solid State Dye Sensitizer Dye Solar Cells : Varying Relative Ratio of Co-solvents and Dye Extracting Temperature
The natural dye solutions were extracted from red Spinach leaves and used as photosensitizer in solid-state dye-sensitized solar cells (ssDSSCs). The optimal conditions for dye concentration and extracting temperature ...
Fabrication of Titanium Dioxide Nanotubes Array For Photoanode in Mesoscopic Solar Cells
One dimensional (1D) nanostructures have been attracting the research interest and have many potential applications including mesoscopic solar cells. In this work, 1D titanium dioxide (TiO2) nanotubes array have been ...
Crystalline Phase and Photocatalysis Activity of Electrochemically Anodized Titania Nanotubes
Titania (TiO2) nanotubes were developed by electrochemical anodization method. The crystalline phase of TiO2 nanotubes annealed at different temperatures was identified by X-ray diffraction. Anatase phase TiO2 started ...
