Abstract

In optoelectronics system, the copper sulfide powder plays an important role as a thin film layer. This paper covers fabrication of Copper sulfide (CuS) Powder and its characterization. The fabricated Copper sulfide powder gives better result as compared to commonly used Copper sulfide (CuS) available in the market. In this experiment, the Copper sulfide powder (CuS) was coated on the tubes as a thin film and measured the outlet water temperature 80°C. and also found that percentage of coating is directly proportional to increasing temperature of the system. The performance and the efficiency of the Solar water heating (SWH) system can be improved by coating Copper sulphide powder (CuS) on the tubes. Chemical composition, microstructure and the particles of the fabricated Copper sulfide (CuS) powder has been analyzed by using SEM, FTIR, UV Spectroscopy. The elemental analysis by EDS revealed that the product contained two kinds of elements Cu and S2. The fabricated powder was uniformly coated on the Aluminum foil at the constant temperature of 303 K with varying coating time by Electro less chemical method. Thin Film coated with less time can be used for photothermic application. The quality of thin film coating of CuS by this method are excellent when comparing with other commonly coating method of thin films used in the ETC type solar heating tubes. Fabicated CuS powder can be used for optical devices, Fabrication of solar cells and Solar heating water applications. The experiment analysis shows that the fabricated CuS has good stability of absorbing of thin film coatings and optical properties. These low-cost and non-toxic materials can be useful in solar energy conversion applications.
