BEHAVIOR OF SOLUTION GROWN CdS FOR THIN-FILM SOLAR CELL TECHNOLOGIES†

Study of the physical property of the cadmium sulfide thin film depending on the process condition

“…In addition, as one makes thinner CdS films, the probability to make a short circuit between the CdTe layer and the front contact is increasing. In order to prepare transparent and high resistive CdS thin films with the good conformal coverage, there are various deposition techniques such as the chemical vapor deposition, the electro deposition [3], the spray method [4], the RF sputtering [5] and the chemical bath deposition [6][7][8][9]. So far, the chemical bath deposition (CBD) has been known to be the most promising method to fabricate the state of the art CdTe solar cell.…”

Characterization of CdS films prepared by chemical-bath deposition

“…Among various techniques that can be used for the preparation of thin CdS films (thermal evaporation, chemical spray, electrodeposition and sputtering), CBD is a simple and inexpensive method. In CBD the rate of growth is controllable by pH, temperature and the relative concentrations of the reactants in the bath solution [2][3][4]. The alkaline bath solution (pH > 9) normally consists of a cadmium salt, thiourea [SC(NH 2 ) 2 ], NH 4 OH and a complexing agent such as NH 4 Cl.…”

Preparation of Multi-Wall Carbon Nanotubes/Graphene Composites with Cadmium Sulfide in Dye-Sensitized Solar Cells (DSSCs)

“…Some of them are using physical methods and the others are using chemical methods. Among these are spray deposition, electrodeposition, pulsedlaser deposition [8] [9], RF sputtering [9] [10], sol-gel, hydrothermal processes solvothermal processes [11] [12] [13] [14], vacuum evaporation [15], successive ionic layer adsorption and reaction (SILAR) [16], chemical bath deposition (CBD) [17] [18] [19], chemical vapor deposition (CVD) [9] [20]. Recently, studies have demonstrated that the integration of composite science and technology constituents into the polymeric matrices of electronic components results in several orders of magnitude enhancement of the electrical conductivity.…”
