Metal Oxide Thin Films Used as Solar Absorbers: Review| Chapter 1 | Progress in Chemical Science Research Vol. 1

Metal oxide materials are gaining popularity due to their remarkable physical, optical, and electrical qualities. Laser devices, supercapacitors, solar cells, biosensors, biomedicine, photo catalysis, and luminous materials are just a few of the uses for these thin films. Many scientists have documented the synthesis of metal oxide films utilising various deposition processes such as physical and chemical approaches. Characterization is a crucial step in ensuring that the thin films produced can be utilised for certain applications. Based on a literature study, the major goal of this work is to report on the creation or improvement of thin film based solar cells, perovskite solar cells, and dye sensitised solar cells. The photovoltaic properties (short-circuit current, open-circuit voltage, fill factor, and efficiency) of solar cells made under diverse circumstances were examined. The many types of solar cells were built, and the efficiency of power conversion was highlighted. Metal oxide films might be used as an electron transport layer, electron conducting medium, anti-reflecting layer, and hole transport material, according to the overall experimental results.

Current Progress in Applied Materials Research: Thin Film, Carbon Nanotube and Activated Carbon | Chapter 12 | Recent Advances in Science and Technology Research Vol. 6

 

Nano materials are an important field in the science and technology world. Activated carbon, carbon nanotube and metal chalcogenide thin films were explored in this work. Activated carbon has been prepared by carbonization and activation processes using various raw materials. To improve the texture properties and generate better adsorption power, several activation agents such as KOH, NaOH, zinc chloride, phosphoric acid, sulphuric acid have been used. Due to high surface area and high porosity structure, the carbon obtained could be served as adsorbent to remove pollutant, dyes from wastewater. Thin films of metal chalcogenide have been synthesised through different techniques of deposition. For solar cells, sensor devices, laser devices and opto-electronic applications, the films obtained could be used. Different devices have been used to investigate the characterization of various forms of thin films. Many researchers have studied carbon nano tubes due to strong mechanical power, conditions, etc. Such stability, such resistance to corrosion. Ethernet cable, USB and coaxial cable could be used for this.
