Download or read book Electrodeposition of Alloys written by Abner Brenner and published by Elsevier. This book was released on 2013-10-22 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrodeposition of Alloys: Principles and Practice, Volume I covers the general and theoretical aspects of the electrodeposition of alloy containing silver and/or copper. This book is organized into three parts encompassing 21 chapters. The first part considers first the history of electrodeposition, the applications of electrodeposited alloys, and the practical considerations involved in electrodeposition. This part also deals with the effect of operating variables on composition of electrodeposited alloys, and the physico-chemical properties of the alloy. The second part focuses on the theoretical aspects of alloy electrodeposition. This part includes discussions on the role of cathode diffusion layer, the effects of complexing agents, and the concept of alloy plating. The third part discusses the practical aspects of the electrodeposition of alloys, focusing primarily on the electrodeposition of alloys from aqueous solutions. This part examines first brass and bronze plating, followed by the electrodeposition of copper-tin, silver, and iron containing alloys. This book is directed toward electrochemists and researchers.
Book Synopsis Electrodeposition of CIGS/CZTS Components from Aqueous Electrolytes by : Salem Shames Al Zahmi
Download or read book Electrodeposition of CIGS/CZTS Components from Aqueous Electrolytes written by Salem Shames Al Zahmi and published by . This book was released on 2015 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thin films for solar panels can be made more cost-effective if they can be produced by electrodeposition. This exploratory work investigated various electrolytes to be used for a variety of photovoltaic devices, including Cu-In-Ga-Se (CIGS), Cu-In-S (CIS) and Cu-Zn-Sn-S (CZTS) materials, and any combination of them. In particular, two important subset alloy systems were examined in detail: CuSnIn and CuSnZn. The latter alloy combination was then studied with different sources of sulfur in the electrolyte to produce CZTS. To complement and help interpret the electrochemical experiments a complexation model was developed. A variety of electrochemical techniques was used to inspect the polarization behavior, and deposits were fabricated at constant potential. The resultant compositions was analyzed by x-ray fluorescence (XRF) spectroscopy and the surface structure inspected by scanning electron microscopy (SEM). A comparison of the electrodeposition of CuSn with and without In was examined in a citrate electrolyte, with excess citrate, in an effort to fully complex the species to promote electrolyte stability. The current potential behavior of each reacting species, Cu, Sn and In, and their alloy combinations SnIn, CuSn, CuIn, CuSnIn, was examined. The most significant results were that when Sn is codeposited with Cu or CuIn there is an enhancement in the partial current densities of Sn. Also, the reduction rate of In(III) was observed to be accelerated, but only when both Cu and Sn were present. The In(III) reduction enhancement on stationary electrodes occurred when Cu(II) reduction was under mass transport control. In order to evaluate if the In(III) rate was a consequence of the mass transport effect, an upside down rotating disk electrode was used. Even when the deposition occurs in the kinetic range of the codepositing species, the In(III) rate is still enhanced. No change in the surface morphology and roughness occurred when CuSn is codeposited with In, thus the enhancement of In(III) was not due to a change of surface area. An unwanted result was that precipitation in CuSn and CuSnIn electrolytes have been observed after a couple days of preparing the solutions, but could be circumvented at low pH, by changing the type of complexed Sn species. The effect of Zn concentration in the current potential behavior of Zn, CuZn, SnZn, and CuSnZn was investigated in a mixing environment using the upside down rotating disk electrode at pH 2. A shift to more negative potential was observed on the CuZn (or SnZn) polarization when Zn concentration was increased in the electrolyte. A first order reaction order of Zn was found when Zn was singly deposited. The effect of codepositing Zn with Cu (or Sn) on the reaction order of Zn was studied by varying the Zn concentration in the electrolyte. An increased in the apparent reaction order of Zn was observed when Zn was codeposited with Cu (or Sn). It was found to be related to displacements reactions occurring during deposition, and consistent with EIS measurements. Based on knowledge gained in the CuSnIn and CuSnZn experiments, an electrolyte for depositing CZTS was developed using different sources of sulfur where thiourea and thiosulfate were examined. The presence of thiourea (or thiosulfate) in the electrolyte was found to have an inhibiting effect on the reduction rate of Sn for the first time. These findings are a step towards creating CZTS by electrodeposition in a one-step process without the need for a secondary sulfurization step.

Book Synopsis Electrochemical Fabrication of Thin Film Photovoltaic Devices (CIGS & CIGSS) by : Mahfouz Ali Saeed
Download or read book Electrochemical Fabrication of Thin Film Photovoltaic Devices (CIGS & CIGSS) written by Mahfouz Ali Saeed and published by . This book was released on 2014 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Copper Indium Gallium Selenium (CIGS) films are attractive for photovoltaic applications due to their high optical absorption coefficient. Generation of CIGS films by electrodeposition is particularly appealing due to the relatively low capital cost and the relatively high throughput. Numerous publications address the electrodeposition of CIGS; however, very few recognize the significance of transport, and consequently, deposition following published processes often leads to deficient films. We introduce here a new electrolyte composition, which is far more dilute than systems that had been previously described, and which yields much improved CIGS films. The electrolyte consists of: 0.4-0.6 mM CuCl2-H2O; 0.28-0.5 mM InCl3; 0.6-0.85 mM H2SeO3; and 0.35-0.6 mM GaCl3. PHydrion was used as buffer, and LiCl was used as a supporting electrolyte. Deposition experiments, under ambient temperature and pH=1.9 were carried on a rotating disk electrode which enabled to quantitatively control the transport rates. While the conventional electrolyte, which was ten times more concentrated yielded a powdery deposit which was shed into the electrolyte, the new, low concentration electrolyte produced in the preferred potential interval of -0.64 = E = -0.76 V/NHE, smooth deposit, with uniform composition in the desired range across a broad rotation speeds. We further extend the deposition process to the generation of Cu(In,Ga)(S,Se)2 [CIGSS] which offers potential advantages over CuInGaSe2 [CIGS] as a photovoltaic film due to its wider band-gap. Previously reported CIGSS fabrication requires elements addition from the vapor phase -- a slow and difficult to control process. Our electrolyte for the electrodeposition of CIGSS is similar in composition to that used for CIGS electrodeposition, however, it contains also 0.35 mM Na2S2O3, as a source for sulfur. The process provides the CIGSS compound in the desired stoichiometry without requiring elements addition from the vapor phase during annealing. Lastly, we introduce new electrochemical processes for the generation of complete CIGS and CIGSS functional photovoltaic devices, based entirely on electroplating. In addition to the absorber layer, electrochemical processes for the electrodeposition of the cadmium sulfide, and the pure and doped zinc oxide layers are described. The substrate has been stainless-steel coated with a molybdenum barrier layer, enabling continuous strip plating. Complete electrodeposited devices were generated and tested exhibiting efficiencies ranging from 2 to 6%. This is the first that such a comprehensive process had been described, leading the way to a potential fabrication of an entire device using an electrochemical route, enabling effective manufacturing integration and scaling.
