Deposition Techniques

Thin film is used for sensing and electronic devices applications. Various techniques are used for thin film deposition. This chapter presents the Spray pyrolysis deposition technique used for the growth of thin films sensing and device material. Spray pyrolysis is an inexpensive method to grow good crystalline thin film compared to other thin film deposition techniques. The chapter gives an overview of the spray process used for thin film deposition. Basic setup for this process is explained. Parameters affecting the deposition process is explained, as are the various spray methods. Finally, some examples of spray pyrolysis in different applications like a gas sensor, UV photodetector, solar cell, photocatalysis, and supercapacitor are discussed.

Czts Thin Films

Cu2ZnSnS4 generally abridged as CZTS is a potential material for economical thin film solar cells, due to its appropriate band gap energy of around 1.5 eV and great absorption coefficient of above 104 cm-1. All the constituents of this material are plentiful in the earth’s crust, and they are non-hazardous making it an elegant alternative. Subsequent to the early achievement of the CZTS based solar cell with its light to electrical conversion efficiency of 0.6%, significant advancement in this research area has been attained, particularly in the last seven years. Currently, the conversion effectiveness of the CZTS thin film solar cell has enhanced to 24%. More than 500 papers on CZTS have been available and the greater part of these converses the preparation of CZTS thin films by diverse methods. Until now, many physical and chemical methods have been engaged for preparing CZTS thin films. Amongst them, spray pyrolysis is a flexible deposition technique. Spray pyrolysis is a simple deposition technique that finds use in widespread areas of thin film deposition research. This method is appropriate for depositing good quality films with low cost, clean deposition, and simplicity and flexibility in the manufacturing design. This script, reviews the synthesis of CZTS semiconductor thin films deposited by spray pyrolysis. This analysis initiates with a portrayal of the spray pyrolysis system, and then establish the CZTS and preparation of the CZTS precursor for coating. A review of spray pyrolysis of CZTS thin films are discussed in detail. To conclude, we present perspectives for advancements in spray pyrolysis for a CZTS based solar cell absorber layer.

To overcome the difficulties in the fabrication of nanoscale linewidth standards with lithography, a method of fabricating nanoscale multiple linewidth standards based on multilayer thin film deposition technique is presented in this paper. This method can be implemented easily and does not require the use of complex and expensive techniques, and it has advantage of well-controlled linewidth over various millimetres (using thin film thickness control) and versatile materials selection of the grating lines. Nanoscale multiple linewidth samples with nominal linewidths of 20 nm, 25 nm, 35 nm have been fabricated with the presented method. The lines of the fabricated samples have uniform attributes and good linearity over hundreds microns.
