Book Description
CuInSe2 (CIS) and Cu(In,Ga)Se2 (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.

Formation of Cadmium Telluride Thin Films and Metal Thin Films Using Innovative Electrochemical Deposition Method for Photovoltaic Applications
Author: Xiaoyue Zhang
Publisher:
ISBN:
Category :
Languages : en
Pages : 310
Book Description
This dissertation discusses the formation of cadmium telluride (CdTe) using potential pulse atomic layer deposition (PP-ALD) and metal thin films (copper and gold) using surface limited redox replacement (SLRR). Both materials play important roles in photovoltaic devices. PP-ALD is an electrodeposition methodology similar to co-deposition because it uses one solution containing all precursors. However, instead of maintaining one deposition potential as with codeposition, potentials are varied quickly between a cathodic and an anodic potential throughout deposition. Each short pulse aims to limit the amount deposited during cathodic potential and strip the excess in the following anodic potential so that thermodynamically stable compound remains without elemental excess buried beneath the later-grown film. To achieve high quality CdTe thin film, changes in deposition potential and solution flow effects were first monitored and optimized. Parametric variables for controlling the Cd/Te ratio and morphology are also established. X-ray diffraction (XRD), Scanning electron microscope (SEM), Electron probe microanalysis (EPMA), Energy dispersive X-Ray Analyzer (EDX) were used to characterize the resulting CdTe films. Results indicated that deposited CdTe was stoichiometric, high crystalline with a smooth, continuous morphology using an optimized PP-ALD method. The optimized PP-ALD method was also applied on nanostructured Au electrodes. Initial results showed high quality deposits with reproducible stoichiometry, which could open pathways for semiconductor and nanostructure incorporation. Cu and Au thin films were formed on metal and semiconductor substrates via surface limited redox replacement (SLRR). An atomic layer of cadmium was first deposited as a sacrificial layer, and then replaced with ions of more noble metals such as Cu2+ or Au3+ to form Cu or Au atomic layer. Uniform and reasonably flat metal thin films with controllable thickness were produced by multiple repetitions of SLRR cycles with great linear growth with respect to cycle numbers. The resulting metal thin films were characterized using coulometry, SEM, EDX and EPMA. They confirmed deposited metal thin films had a conformal, flat morphology with no roughness development, nor Cd incorporation in the deposition process.
