The impact of precursor thickness and surface roughness on the power factor of Cu2ZnSnS4 (CZTS) at near room temperature: Spin-coating deposition
This work investigated the thermoelectric properties of Cu2ZnSnS4 (CZTS) thin films deposited on the soda-lime glass using spin-coating techniques with different layers. X-ray diffraction (XRD) pattern confirms the increase of the layer number leads to improve the crystallite size and all the films exhibit tetragonal structure with the presence of secondary phases. EDX shows a reduction of Cu and Zn contents while an increase in Sn contents is observed when the thickness increases. Surface topography is also carried out to study the surface roughness and it is found to be minimum when we deposit 4 layers. The absorption spectra show that CZTS exhibit a bandgap varied between 1.33 and 1.9 eV, the resistivity and the Seebeck coefficient have been found to increase with the increase of surface roughness. This investigation indicates that Cu2ZnSnS4 thin films can be a suitable material for thermoelectric application at near room temperature range.
期刊介绍：
Micro and Nanostructures is a journal disseminating the science and technology of micro-structures and nano-structures in materials and their devices, including individual and collective use of semiconductors, metals and insulators for the exploitation of their unique properties. The journal hosts papers dealing with fundamental and applied experimental research as well as theoretical studies. Fields of interest, including emerging ones, cover:
• Novel micro and nanostructures
• Nanomaterials (nanowires, nanodots, 2D materials ) and devices
• Synthetic heterostructures
• Plasmonics
• Micro and nano-defects in materials (semiconductor, metal and insulators)
• Surfaces and interfaces of thin films
In addition to Research Papers, the journal aims at publishing Topical Reviews providing insights into rapidly evolving or more mature fields. Written by leading researchers in their respective fields, those articles are commissioned by the Editorial Board.
Formerly known as Superlattices and Microstructures, with a 2021 IF of 3.22 and 2021 CiteScore of 5.4
