SnS: Cu thin films have been successfully prepared on Pyrex substrates using low cost chemical bath deposition (CBD) technique with different copper doped concentration (y = [Cu]/[Sn] = 5%, 6%, 8%, 9% and 10%). The structure, the surface morphology and the optical properties of the SnS:Cu films were studied by X-ray diffraction (XRD), atomic force microscopy (AFM) and spectrophotometer measurements, respectively. To obtain a thickness of the order of 780 ± 31 nm for absorber material in solar cell devices, a system of multilayer has been prepared. It is found that the physical properties of tin sulphide are affected by Cu-doped concentration. In fact, X-ray diffraction study showed that better cristallinity in zinc blend structure with preferential orientations (111)ZB and (200)ZB, was obtained for y equal to 6%. According to the AFM analysis we can remark that low average surface roughness (RMS)value of SnS(ZB) thin film obtained with Cu-doped concentrations equal to y = 6%, is about of 54 nm. Energy dispersive spectroscopy (EDS) showed the existence of Cu in the films. Optical analyses by means of transmission T(λ) and reflection R(λ) measurements show 1.51 eV as a band gap value of SnS:Cu(6%) which is nearly equal to the theoretical optimum value of 1.50 eV for efficient light absorption. On the other hand, Cu-doped tin sulphide exhibits a high absorption coefficient up to 2 × 106 cm−1, indicating that SnS:Cu can be used as an absorber thin layer in photovoltaic structure such as SnS:Cu/ZnS/SnO2:F and SnS:Cu/In2S3/SnO2:F, where ZnS and In2S3 are chemically deposited in a previous studies.

Structural analysis of indium sulphide thin films elaborated by chemical bath deposition

Synthesis and characterization of nanocrystallized In2S3 thin films via CBD technique

Nowadays, removal of pollutants from urban wastewater treatment plants (UWTPs) remains a big challenge. The macrolides antibiotics are particularly present in higher levels in unprocessed wastewater and are often partially reduced by conservative managements. The photocatalysis process was categorised amongst the miscellaneous progressive oxidation methods (AOPs) with high capacity for successful removal of pharmaceuticals from numerous aqueous matrices. In the present work and for the first time, chemical spray pyrolysis was used to synthesize Cu2Fe1-xAlxSnS4 (x = 0, 0.25, 0.50, 0.75 and 1) thin films. Sprayed films were investigated using many techniques such as: MAUD software (Material Analysis Using Diffraction), scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDX), spectrophotometer and Hall effect and drop shape analysis system (DSA). MAUD software revealed a polycrystalline nature for Cu2AlSnS4 (CATS) with slight shift of diffraction peaks depicted at 2θ = 27.84°, 47.03° and 55.93°, which identified respectively to (0 0 2), (1 1 0) and (1 1 2) plans. In addition, SEM images show that Cu2AlSnS4 grows with many rod-shaped structures that closely attached to each other. It is clearly seen that CATS thin film exhibited the highest extinction coefficient value (Kext) than other CFATS films. Additionally, a special emphasis focused on surface wettability of CFATS films showing a hydrophilic character surface using spiramycin (SPY) macrolide antibiotic liquid. Its worth mentioning that the hydrophilic type has a distinguished helpful role on the photocatalytic process that may be associated with the active surface area and the high adsorption of liquid. Based on the relationships between photocatalysis and hydrophilicity, the behaviors of SnO2:F, CATS films and coupled CATS/SnO2:F photocatalysis were tested using 20 mg/L of spiramycin (SPY) macrolide antibiotic in aqueous solution. Spiramycin removal competence using SnO2:F, CATS films and coupled CATS/SnO2:F was increased after being reused 120 min. Consequently, the current work can open a new area for effectiveness of CATS/SnO2:F surface which recognized in order to manufacture a self-disinfecting and self-cleaning, removal of high antibiotics bacteria-resistance.
