Synthesis and Characterization of Nanostructured Thin Films of (CdS)0.6 Se0.4 for Solar Cell

Abstract

Abstract:The high quality thin films of (CdS) 0.6 Se 0.4

Properties of the CdSxTe1-x solid solution: As a single product and as a part of the CdS/CdTe solar cell

“…In CdS/CdTe thin film solar cells, alloy formation has both beneficial and detrimental effects on device performance depending on how the alloys are formed, their composition and their compositional distribution. The proper amount of interdiffusion is necessary for a superior efficiency solar cell [8]. However, diffusion of CdS into CdTe is a faster process than that of CdTe into CdS, and is more difficult to control, especially for cell structures with ultra-thin, <100 nm, CdS films.…”

“…Polycrystalline CdSxTe1-x and CdS1-yTey thin films can be produced by several methods such as: thermal evaporation (co-evaporation of CdS and CdTe) [7][8][9], RF magnetron sputtering [9], brush plating [10], pulsed laser deposition [11], pulse plating [12], closed space sublimation [13][14][15][16][17], metal organic chemical vapor deposition MOCVD [18], chemical bath deposition (CBD) [19], and spray pyrolysis [20][21][22] by first producing CdS films then annealing in Te atmosphere. It is well known that the properties of produced films are affected by the deposition technique and deposition parameters used, such as deposition rate, substrate temperature, and thickness of the films [8].…”

“…Several authors [5,8,10,12,13,[20][21][22] produced and characterized CdSxTe1-x thin films, and others used computational methods to study the CdSxTe1-x solid solution [23], but there is a need to have a review about the production, properties, and significance of CdSxTe1-x solid solutions inside and outside the CdS/CdTe solar cell. The aim of this work is to review the significance and some properties of this alloy when produced as a separate product and in the interfacial region of the CdS/CdTe thin film solar cell.…”

Influence of Thickness on Structural and optical properties of the CdS single crystal nano structure thin films Deposited Via Thermal evapovation

“…In terms of structure, it has been reported that the CdS can exist in cubic (Zinc blend) phase [6][7][8][9][10][11], hexagonal phase of the two phases, depending on the method of preparations and the condition synthesis [12,13]. It has different commercial applications, such as solar cell [14], photo detector [15], LED [16], FET [17], pixel electronics and various semiconducting devices [18]. Various approaches were used to deposit the CdS thin films, comprising evaporation by vacuum [19], and chemical bath deposition (CBD) [20], sol-gel [21] and so on.…”
