“…Figure 3a–c show the full width at half maximum (FWHM) of (112) peak and calculated mean crystallite grain size of CZTS thin films as a function of the varied concentration of CuCl 2 , ZnCl 2 , and SnCl 2 aqueous precursor solutions that were annealed at a temperature of 350 °C. The grain size enlarges with increasing CuCl 2 concentration, as shown in Figure 3a because of the increase of Cu atomic content in the CZTS thin films [27,28]. This increase in the grain size might be due to agglomeration of grains.…”

Cu 2 ZnSnS 4 (CZTS) thin films were deposited on glass substrates by using spin-coating and an annealing process, which can improve the crystallinity and morphology of the thin films. The grain size, optical gap, and atomic contents of copper (Cu), zinc (Zn), tin (Sn), and sulfur (S) in a CZTS thin film absorber relate to the concentrations of aqueous precursor solutions containing copper chloride (CuCl 2 ), zinc chloride (ZnCl 2 ), tin chloride (SnCl 2 ), and thiourea (SC(NH 2 ) 2 ), whereas the electrical properties of CZTS thin films depend on the annealing temperature and the atomic content ratios of Cu/(Zn + Sn) and Zn/Sn. All of the CZTS films were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDXS), Raman spectroscopy, and Hall measurements. Furthermore, CZTS thin film was deposited on an n-type silicon substrate by using spin-coating to form an Mo/p-CZTS/n-Si/Al heterostructured solar cell. The p-CZTS/n-Si heterostructured solar cell showed a conversion efficiency of 1.13% with V oc = 520 mV, J sc = 3.28 mA/cm 2 , and fill-factor (FF) = 66%.

“…The photoelectrochemical performance of CZTS thin films grown at high temperature was studied by Bhosale et al by varying copper concentration in the precursor solution. The molar concentration of copper was varied in steps of 0.05 M from 0.15 to 0.30 M. The kesterite peak intensity along (112), (002), (114), (220), (312), (008), and (332) (JCPDS 26‐0575) got increased as the crystallinity of the sample increased on increasing the molarity of copper.…”

A review on growth optimization of spray pyrolyzed Cu ₂ ZnSnS ₄ chalcogenide absorber thin film

et al. 2019

Summary The progress of solar cell technology in the development of clean and economic quaternary compound copper zinc tin sulfide (CZTS)‐based absorber thin films using the spray pyrolysis technique are presented in this review. CZTS (Cu2ZnSnS4) is the only potential competitor for the existing solar thin film absorbing materials owing to its environment‐friendly Earth abundant constituents. Even though different nonvacuum thin film technologies have been developed for the large area fabrication of this nontoxic absorber material, spray pyrolysis technique offers more versatility in changing the process parameters which has a direct impact on the cell efficiency. It can be used for depositing a wide variety of materials even with complex composition with good crystallinity, and the method has the advantage of being flexible and straightforward to design and can be quickly adopted for extensive area deposition. A survey on the effects of experimental conditions as well as the nature of precursors on the structural, morphological, electrical, and optical properties on the spray pyrolyzed CZTS thin films is discussed in detail. This analysis certainly could provide a potential to obtain new insights in the fabrication of high‐efficiency CZTS‐based solar cells and to launch it into the commercial market to satisfy the ever‐growing future energy demand.

Low‐Temperature‐Processed Cu₂ZnSnS₄ (CZTS)/CdS/1D‐Titania Tandem Photoanode with Effectual Photoelectrochemical Response

2021

A molecular precursor–based Cu2ZnSnS4 (CZTS) layer deposited at very low temperature (100 °C), without any sulfurization step, over a CdS/1D titania tandem photoanode is explored for its photoelectrochemical (PEC) application. Further, the CZTS‐based tandem photoanode is optimized by varying the composition of Cu and Zn in the molecular precursor solution. With enhanced optical absorption in the visible region and also more efficient separation of the photogenerated charge carriers, the tandem photoanode exhibits an almost 20 times higher PEC response compared to 1D TiO2, on par with the best in the relevant literature.
