Photovoltaics were successfully synthesized using Cu2CdSnS4 quaternary alloy nanostructures on p-type silicon substrate via sol-gel method at different annealing temperatures up to 500 oC. UV-vis and photoluminescence (PL) spectrofluorometers have been utilized to investigate the optical properties of refractive index and optical dielectric constant.
Currently, copper sulphide and silver sulphide thin films have been received a lot of attention from researcher. These films could be used for electronic, photonics, optoelectronic devices, solar cells, solar selective coatings, resistive switches, filament memories, and infrared detectors.
A chalcogenide is a chemical substance including at least one chalcogen anion and at least one electropositive element. In the current scenario, there has been lots of attention in metal chalcogenides, due to their physical and chemical characteristics trade unexpectedly with particle dimension.
Nanostructured thin films (binary, ternary and quaternary) have been prepared using different deposition techniques. During the deposition process, films were deposited onto various clean substrates such as soda lime glass, indium tin oxide coated glass and stainless steel.
In the last two decades, there are several physical and chemical deposition methods have been used to produce nanostructured thin films. Researchers have concluded that both methods present certain advantages over conventional methods and showed promising potential for the deposition process.
Sol gel dip coating technique was employed to produce thin films. Sol gel chemistry is dependent on the nature and particle size of the species. This method includes transformation of liquid solution into solid gel in a phase.
Solar energy is an example of renewable energy. It is free, clean and inexhaustible. Currently, there are two types of semiconductors, namely n-type and p-type. These semiconductors consist of n-type and p-type absorb sunlight, then produce electricity.
