“…Other alkaline electrolytes include zincate (Zn(OH) 4 2− ), which is relatively tolerant to impurities but displays low electroplating efficiencies at high current densities, and the pyrophosphate baths, which are quite expensive . The use of synthetic quaternary ammonium compounds (QACs) as additives permitted the development of modern cyanide‐free alkaline zinc electrolytes .…”

This paper aims at providing an updated overview of the main achievements in the development of solar cells based on Cu 2 ZnSn(S,Se) 4 (CZTS(Se)) Kesterite absorbers obtained by electrodeposition. Although undoubtedly challenging, the ultimate goal is to learn from the past works and build a solid framework for future advances in this field. What is the reason for the lower efficiency of electrodeposited CZTS(Se)-based devices (8%) compared to the world record efficiency achieved with a hydrazine-based solution approach (12.6%)? Can this gap be filled, or there are intrinsic limitations for this achievement? The review is divided into the three main electrodeposition approaches: sequential elemental layer, alloy co-deposition, and chalcogenide co-deposition. It is argued that considerable technical challenges must be overcome for the latter approach to be successfully applied.Plot of the record power conversion efficiencies of Kesterite sulfide-based solar cells obtained by electrodeposition (hollow dots), and world record efficiency of CZTS(Se)-based devices (full dots). The dashed line shows the 15% minimum efficiency threshold considered relevant for potential industrial application.

“…The XRD patterns of Zn-Ni alloys, Zn and Cd coatings are shown inFig. Ni atoms can be incorporated into Zn lattice, 238 which causes a significant distortion of the structure of Zn, resulting in the difference 239 between Zn and Zn-Ni alloys[38]. All the 230 coatings exhibit a crystalline structure in the diffractograms.…”

Corrosion mechanism of nanocrystalline Zn–Ni alloys obtained from a new DMH-based bath as a replacement for Zn and Cd coatings

17Nanocrystalline Zn-Ni alloys were proposed from a new developed 18 5,5'-dimethylhydantoin (DMH)-based bath as replacement of Zn and Cd coatings due 19 to their excellent corrosion resistance and environmental friendly properties. However, 20 the mechanism of better corrosion performance of Zn-Ni samples compared with Zn 21 and Cd coatings was rare to be investigated. In the present study, the corrosion 22 36 impedance spectra (EIS) confirm the above facts that Zn-Ni alloys have better 37 corrosion resistance than Zn and Cd coatings, which can be used as the best 38 alternative to Zn and Cd coatings. 39

“…In the electroplating of metals from aqueous solution, additives have been used to optimize the physical and mechanical properties of the resultant coatings. [11,55,56] The additives work as brightening, levelling or grain-refining agents, where such media have been observed to affect the brightness of the coating, the grain size of metal and the throwing power; indeed, some additives can affect the anodic depolarisation and current efficiency. [57,58] The additives appear to work in either of two ways: in the first, they can be adsorbed on the electrode surface, preventing the metal from being deposited on the sites occupied by the organic molecules.…”

A number of studies into the influence of additives on the electrodeposition of metals from aqueous solution have been reported in the literature. However, very few have studied the influence of additives on metal electrodeposition in Deep Eutectic Solvents (DESs). This work will show, for the first time, the effect of sodium bromide on the electrodeposition of tin, copper, silver and nickel from a deep eutectic solvent (DES)-based ionic liquid consisting of a stoichiometric 1:2 mix of choline chloride and ethylene glycol (Ethaline 200). It is shown that in the presence of sodium bromide, bright and smooth Cu and Ni deposits were formed. Cyclic voltammetry and chronocoulometry have been used to examine the electrochemical properties of the plating liquids in both the absence and presence of sodium bromide. It was found that the redox peak currents of the Sn and Ag electrolytes get smaller when sodium bromide is added to the electrolyte solution. The resultant surface morphologies, topography and roughness of Sn, Cu, Ag and Ni were investigated by scanning electron microscopy (SEM/ EDXS) and 3D optical microscopy (3D). The current efficiency of metal deposits was found to increase when the deposition was achieved from an electrolyte that contained sodium bromide.
