    A copper indium gallium selenide solar cell (or CIGS cell, sometimes CI(G)S or CIS cell) is a thin-film solar cell used to convert sunlight into electric power. It is manufactured by depositing a thin layer of copper, indium, gallium and selenium on glass or plastic backing, along with electrodes on the front and back to collect current. Because the material has a high absorption coefficient. The processes of nickel electrodeposition on Pt / Si () substrate from an aqueous sulfate, Watts, and chloride solution have been studied using electrochemical techniques and atomic force microscopy (AFM). It was found that hydrogen evolution reaction (HER) was shifted more cathodically and the nickel electrodeposition obeys to inhibition process, caused by adsorbed species in surface.

    The co-electrodeposition of copper, indium, gallium and selenium from a pH acid bath onto an FTO substrate in the presence of the additive glycerol (GLR) is studied. The concentration of additive in the bath is evaluated, and conditions are optimised for deposition of Cu(In,Ga)Se2 (CIGSe) thin . electrodeposition potentials and study the relation of ap-plied potentials with the morphology and magnetic prop-erty of the thin films deposited on indium tin oxide (ITO). EXPERIMENTAL A computer-controlled potentiostat was used as a po-tential source. A sulfate bath containing M CoSO 4, M NiSO 4, M FeSO 4 and a buffer solution.

However, it is difficult to manage the effects of this high number of parameters including their interaction effects.

For lessening the possible acidification of the solution during the electrodeposition, the sulfate bath acted as buffer at pH around 2. Potassium hydroxide (Sigma Aldrich) was added to the anodic compartment, at a point far enough from cathodic surface to control pH of electrolyte, without hydroxides formation near : Alessandro Dell'Era, Erwin Ciro Zuleta, Mauro Pasquali, Carla Lupi.

In a recent Russian patent [24], an acidic bath comprising tin sulfate, indium sulfate and sulfuric acid has been used for co-electroplating tin-indium alloy, in which the indium content ranges. Although these approaches [24,25] use acidic baths based on sulfuric acid, to date, there has been no report on co-electrodeposition of Sn and In using a methanesulfonic acid (MSA) based bath, which is currently the most widely-used commercial bath for Sn deposition [e.g., 7,26,27], and has also been used for In deposition [28,29].Cited by: 5.

This article focuses on the electrodeposition of indium and its alloys, such as indium-antimony, indium-gallium, and indium-bismuth, in nonaqueous indium plating baths. It also provides information on the stripping of indium plate from plated components and presents an overview of the specifications, standards, and hazards of indium plating.

Electrodeposition of the Sn-In alloy from a sulfate electrolyte in the presence of synthanol, formalin, and butynediol-1,4 was studied. An electrolyte composition and conditions for obtaining an alloy of prescribed composition are suggested. Effect of copper sulfate on CuZn alloys electroplating from non-cyanide baths are investigated by different electrochemical methods.

Cyclic voltammetry and current transient measurements are used to characterize the CuZn alloys electroplating system in order to analyze the nucleation and growth mechanism. The reduction of Cu and CuZn alloy on sheet iron substrates shows an instantaneous. Copper selenide thin films are successfully deposited using electrodeposition method by combining copper sulfate and sodiumseleno sulfate precursors at room temperature in acidic bath.

The chemical composition was a key factor in preparing high-quality uniform and. electrodeposition. Most of the efforts dealt with Cu2þ sulfate–sulfuric acid solutions, butoxalate [14], nitrate [15], acetate [15], fluosilicate [16, 17], and Culþ chloride [16] solutions were also investigated. In more recent times the following solutions have been evaluated: sulfate–oxalate–boric acid [18], sulfate–.

A mechanism of iron‐group elemental metal and binary alloy electrodeposition is proposed. The one‐dimensional diffusion model of Grande and Talbot is used to determine near‐surface concentrations of the ionic species deemed important for electrodeposition; the current model expands upon the surface kinetics by including the effects of competitive adsorption, site blockage by hydrogen.

Tin oxide (SnO 2) thin films were successfully electrodeposited on indium tin oxide (ITO) coated glass substrate from an acidic aqueous solution containing SnSO 4 at room temperature. Oxygen bubbling was employed so that dissolved oxygen serves as oxygen precursor.

With O 2 bubbling and short deposition time, transparent films were obtained. The composition ratios of the films were.

Tin–indium alloys represent attractive lead-free solder candidates. They show lower values of melting point than pure indium, so that they are investigated as materials with significant applications potential in the electronic industry. Electrodeposition is a very convenient route to prepare Sn–In alloys.

The paper presents several experimental results regarding the electrodeposition of Sn. This invention relates to the art of electrodeposition and particularly to compositions, baths, and processes for the electro-deposition of indium.

In certain of its more specific aspects it relates to the electro-deposition of indium together with another metal, and in certain of its broader aspects it relates to the joint deposition of a. The electrodeposition of Ni-Zn alloy coatings having high nickel content ( wt%) from a sulfamate bath was studied.
