Book Properties of Thin Film Cadmium Sulfide Used in Cadmium Telluride cadmium Sulfide Solar Cell

Download or read book Properties of Thin Film Cadmium Sulfide Used in Cadmium Telluride cadmium Sulfide Solar Cell written by Xiawa Wu and published by ProQuest. This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: CdTe/CdS solar cell is one of the promising low cost high efficiency thin film solar cells. In this work, thin film CdS properties and the effect of CdS surface conditions on CdTe growth and performance of polycrystalline CdTe/CdS thin film solar cells are investigated. Thin film CdS optical, structural and chemical properties both as deposited and after CdCl 2 heat treatment are measured. CdS surface chemical state is studied by analyzing its surface chemistry after different surface treatments. Qualitative and quantitative measurements indicate sulfate and sulfite phases on thin film CdS surfaces as well as single crystal CdS, caused by oxidation in the air. The degree of CdS oxidation is highly dependent on thermal treatment ambient, temperature and time. Results indicate reduction in grain size and smoother morphology for CdTe deposited on heavily oxidized CdS compared to chemically reduced CdS surface. Solar cell open circuit voltage is much lower on cells with heavily oxidized CdS surface.

Book Progress in the Development of High Efficiency Thin Film Cadmium Sulfide Solar Cells

Download or read book Progress in the Development of High Efficiency Thin Film Cadmium Sulfide Solar Cells written by A.M. Barnett and published by . This book was released on 1978 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thin film photovoltaic cells of cadmium sulfide/copper sulfide have been developed and optimized for specific cell designs. The optimization has been achieved by changing material parameters and the technology of the electrical contacts as dictated by detailed analyses of loss mechanisms in the cells. Additional design changes are needed to further increase the energy conversion efficiency in direct sunlight beyond the present value of8.5%. The application of analytic techniques to specific cell designs is responsible for the improvements achieved to date, and it is expected to lead to a basic cadmium sulfide/copper sulfide cell with an efficiency over10%.It is anticipated that the application of similar analytic techniques to a modified cell of cadmium -zinc sulfide/copper sulfide, coupled with constant interplay between theoretical and experimental results will lead to an energy conversion efficiency in direct sunlight of up to 14%.The material properties and electro-optical characteristics of the present high efficiency CdS/Cu2S cells and initial results using the mixed cadmium zinc sulfide will be presented. This paper describes the analysis driven technology innovations which have led to the development of reproducible thin film cadmium sulfide solar cells with energy conversion efficiencies in direct sunlight of greater than 8.5%. A photovoltaic effect in CdS was first reported by Reynolds for a junction made by depositing a thin film of copper on a cadmium sulfide film (1). Later work established that the actual junction was between CdS and Cu2S (2). A substantial number of research efforts have since been conducted on this photovoltaic heterojunction and although some variation exists, cells have generally been made by reacting a vapor deposited cadmium sulfide film with a cuprous ion solution. A major research effort aimed towards space applications was conducted during the 1960's (3,4).These and many other investigators have reported conversion efficiencies in sunlight of between 5 and 6% with a limited number reporting efficiencies up to 70. Thin film cells with energy conversion efficiencies of7.8% when measured in direct sunlight were recently reported (5,6). The methodology and experiments which lead to the further development of 8.5%CdS/Cu2S cells follows.
