Study Of Treatment And Application Of Solar Glass

The energy shortage all over the world promotes development of the alternative energy source. As the key material in solar PV module and plat solar collector, solar glass is widely used in the recent years.Solar glass is new developing industry. Solar glass trade in China has beening developed rapidly. China is becoming the biggest solar glass producer and supplier.With the development of solar glass business, some technical problem and the absence of theory has occured. August of 2008, a project undertook by China Triumph International Engineering Co.,Ltd. about the product line design and relevent production technology has been indentificated. But the research of solar glass processing and application is still deficient. A project in this field need to be practiced.The thesis is to proceed some theoretical analysis and discuss about the problem in solar glass processing and application. Also to give some study on new technical route and to give some suggestion to the industry.The relation between solar transmittance and glass surface texture has been studied. Some suggestion on surface texture optimization and solar transmittance test method is given.The thesis has given a preliminary study on anti-refletion film on solar glass. A coating technology with lower cost by using industrial grade silica sol is developed.Stress and strain on the glass in the PV module has been modeled and FEM simulated. It is discovered that the stress due to module formation is not the main reason to the glass failure. There are some suggestion for the structure optimazation and material selection.The differnt composition and surface texyure has brought thermal transfer differnce between solar glass and ordinary float glass. So the process of tempering must be modified and the selection of furnace is very important.Tipical BIPV IGU reasonable structure has been summerized.And the result of solar glass chemical stability shows the usability in the BIPV IGU structure.The study of thesis will enrich the knowledge of solar glass processing and application. It is also a base for further study.
