Over the past few decades, technological advances have made it possible to deposition of the thin films under vacuum which referred to as "Hard Coatings". These coatings have different applications due to their special structural and physical properties as protective coatings. Hard coatings consist of nitrides, carbides and borides of intermediate metals such as titanium or carbon coatings such as diamonds. These coatings have many applications in improving tools (such as cutting and forming machines) and machine parts like valves. Properties of a thin film of hard coatings can be classified as follows: Structural characteristics such as thickness, crystallography, chemical composition, surface morphology and roughness.Physical and chemical characteristics such as density, electrical properties, magnetic properties, thermal, optical, oxidizability and corrosion.Mechanical properties such as hardness, adhesion, mechanical stress and friction. The…

Pulsed Laser deposition
Proksytic solar cells are a kind of solar cell that combines the structure of Proksytic. This substance is often an organic-mineral hybrid of lead or tin halides. Proksytic materials such as methyl ammonium lead iodide are cheap and easy to make. The structure of Proksytic is a triple structure of materials, and its general formula is ABO3. This structure consists of octahedrons, in which the cations A are located in octahedral cavities. The thin-film propskite solar cells have high conversion efficiency and can be manufactured in cheap and cost-effective ways. Compared to silicon solar cells, which are usually made in multi-stage and expensive processes, propskite solar cells can be constructed easily in laboratory conditions. These cells have been the fastest solar technology ever since. The advantage of propskite solar cells…
