“…In the works mentioned above, little attention was generally devoted to studying the electrochemical behavior of Se(IV) at the SnO 2 electrode, meaning that information on this behavior is still relatively scarce. A literature survey shows that only a few papers have discussed the reduction of Se(IV) on SnO 2 [5,13,[24][25][26].…”

Preliminary results regarding the electrochemical behavior of Se(IV) in sodium citrate solution on a polycrystalline SnO 2 electrode are presented. A schematic diagram of the energy levels for an n-type SnO 2 electrode in contact with the working electrolyte was constructed. The results of cyclic voltammetry (CV) show that SeO 3 2− reduction occurs through a surface state in a complex multistep pathway. After a minute amount of Se is deposited, the electrode is expected to behave locally like a Schottky diode in contact with the solution. CV analysis and current transient results indicate that selenium growth on the polycrystalline SnO 2 surface proceeds without nucleation. A thin Se film obtained at a potential of −0.8 V vs. Ag|AgCl, KCl (sat) was analyzed by lateral force and atomic force microscopy.

“…The presence of cracks in Ga-containing layers is often a serious problem [39,47], though it can be reduced through the use of alcohol-aqueous solutions [48] or supporting electrolytes such as LiCl or Li 2 SO 4 with gelatin as brightening additive [49]. Complexing agents such as citric acid/citrate [50,51], thiocyanate [52], sodium sulfamate [53], sulfosalicylic acid [54], etc., were often used to improve the composition and morphology of the CIGS films. These additives form complexes with the metal ions in the solution such as Cu, thereby resulting in controlled deposition rates and hence the morphology [55,56].…”

“…These additives form complexes with the metal ions in the solution such as Cu, thereby resulting in controlled deposition rates and hence the morphology [55,56]. Good quality CIGS thin films were also prepared from sulfate-citrate and chloride-citrate solutions [53,57,58] and control of the optical band gap by increasing the Ga content in the films was demonstrated [59].…”

CuInSe 2 (CIS) and Cu(In,Ga)Se 2 (CIGS) semiconductors are the most studied absorber materials for thin films solar cells due to their direct bandgap and large absorption coefficient. The highly efficient CIGS devices are often fabricated using expensive vacuum based technologies; however, recently electrodeposition has been demonstrated to produce CIGS devices with high efficiencies and it is easily amenable for large area films of high quality with effective material use and high deposition rate. In this context, this chapter discusses the recent developments in CIS and CIGS technologies using electrodeposition. In addition, the fundamental features of electrodeposition such as direct current, pulse and pulse-reverse plating and their application in the fabrication of CIS and CIGS films are discussed. In conclusion, the chapter summarizes the utilization of pulse electrodeposition for fabrication of CIS and CIGS films while making a recommendation for exploring the group's unique pulse electroplating method.

“…The electrolyte was stabilized using a buffer of pH 3 (pHydrion mixture of sulphamic acid and potassium biphthalate) along with LiCl as supporting electrolyte [55]. Recent works by Liu et al have suggested that by increasing the sodium sulfamate concentration, (Cu + Se)/ (In + Ga) decreases, while gallium content increases and the film composition transforms from Cu rich to Cu poor [58]. Using KCN − as the complexing agent, the reduction potential difference between of Cu 2+ and Ga 3+ was only 80 mV, whereas 870 mV difference for un-complexed (Cu,Ga) species [59].…”

Thin-film solar cell devices based on copper indium gallium diselenide (CIGSe) chalcogenide materials fabricated by vacuum-based deposition techniques have already achieved lab scale efficiency beyond 21%. For industrial-scale applications, non-vacuum deposition technique such as electrodeposition and screen printing is considered to be suitable approaches for reducing the device fabrication cost. Moreover, electrodeposition has the potential to prepare large area thin films as it requires cheap raw material sources and equipment capital. Hence, it is imperative to understand the current status and advancements in the electroplating techniques of the CIGSe thin films. This article reviews on the experimental advances in electroplating of ternary CuInSe 2 and quaternary CIGSe. Various approaches in electrodeposition, influential experimental parameters, and the deposition mechanisms which are related to the final cell efficiency are discussed in detail.
