“…As a final comment, it can be underlined that the interpretation of the results reported in this paper has a general validity for nanostructured metal oxides used for RH sensors, for which chemisorption is followed by multilayer physisorption and, finally, by water condensation in the micropores or mesopores, and can help in the interpretation of data obtained from different nanostructured active materials [38].…”

In this paper, we investigate humidity sensing through impedance measurements with TiO2 nanoparticles (about 6 nm in diameter). The transient behavior and the impedance spectra are measured and interpreted from the theoretical point of view. Large responses are shown especially in the relative humidity range from 30% to 80%, which are essentially explained by condensation in the nanopores. The effect of the addition of Au nanoparticles is investigated and as expected, the Au/TiO2 interfaces allow for dramatically reducing the sensing film response time and above all, its recovery time; moreover, it seems to favor condensation when the relative humidity overcomes 70%.

“…Presences of water, as well as thiourea are observed in the range of 3550-3750 cm -1 [32]. As a common observation, the shifts indicate a rearrangement of the CZTS network toward that of the stoichiometric structure with a lower structural disorder which gives rise to 2-D nanoplate morphologies witnessed in SEM analysis.…”

“…The peak at 626 and 664 cm −1 is assigned to the ZnS band. The presence of sulphide ions in vibrational modes are observed as broad bands around 858 -893 cm −1 [32]. The peak observed around 1050-1100 cm -1 and 1400-1460 cm -1 is due to NH2 vibrational mode of thiourea.…”

Fabrication of economically viable photocathode for hydrogen energy production through solar water splitting is a major research among the scientific community for a decade. P-type compound Cu2ZnSnS4 (CZTS) is very interesting material due to its absorption property, earth-abundant constituents and environmental friendliness that serves as a suitable candidate to act as a photocathode. In the present work, Cu2ZnSnS4 (CZTS) nanoparticles are synthesized by simple one-step chemical method and annealed at 350 °C for three different times (60 minutes, 90 minutes and 120 minutes). The effect of annealing time on the structural, optical and photoelectrochemical properties are investigated. XRD pattern indicates the formation of tetragonal crystal structure and the crystallinity increases according to the annealing time. 2-D nanoplate morphology is obtained for the sample that was annealed for 120 minutes. From the absorption spectra, it was found that the band gap decreases with increase of annealing time. Further, the prepared nanoparticle thin films are used as a cathode for photoelectrochemical water splitting application. Among these, the nanoparticles that are annealed for 120 minutes showed higher photocurrent density when compared to nanoparticles annealed for 60 minutes and 90 minutes.

Recently, Cu2ZnSn(S,Se)4 (CZTSSe)‐based kesterite thin films have received growing attention in a wide variety of fields due to their suitable physico‐chemical asset nano‐ and micro‐scale. The low elemental cost, earth abundance, and environment‐friendly nature have widened the scope and made it a potential material for developing next‐generation technology. The kesterite thin films have already shown their potential in thin‐film photovoltaics (PVs) with a record efficiency of nearly 12.6%. Apart from solar cells, they have also demonstrated their widespread applicability in the field of photodetectors, gas sensors, thermoelectrics, solar water splitting, energy storage, humidity sensors, antibacterial activities, and many more. This review aims to present an overview of the advancement in the CZTSSe‐based kesterite thin films in terms of synthesis, material properties, and their use in various applications. A comprehensive review of each device application contains ongoing progress, device fabrication, and related issues. Furthermore, this review emphasizes kesterite materials and possible solutions to proposed pitfalls, thus strengthening kesterite's perspective.
