Preparation and characterization of undoped antimony sb zinc zn bismuth bi doped and polyol assisted cuins2 thin films by spray pyrolysis

Abstract

The direct conversion of sunlight into electricity using photovoltaic newlineproperties of suitable material is an elegant energy conversion process The newlinemajor key issue in this area of research is low cost manufacturing processes newlineThin film solar cells have many advantages including low cost processing newlinelight weight and flexibility in comparison to the conventional silicon based newlinesolar cells CuInS2 thin film is one of the most promising ternary chalcopyrite newlinematerials for the solar cell absorber Therefore investigations have been made newlineon the effect of suitable dopants on the physical and optoelectronic properties newlineof CuInS2 and Sb Zn Bi materials and polyol assisted which are motivated newlineto find their suitability in developing efficient and low cost solar cells and it is newlineused the low cost spray pyrolysis technique It also gives the available newlineliterature review on CuS2 SbCl3 ZnCl2 InCl3 and BiCl2 films their materials newlineproperties and preparation techniques The aim and scope of the present thesis newlineis also elaborated newline newline
