摘要
Abstract
Multicrystalline wafer production is a part of photovoltaic products' life cycle which costs more energy and has a greater environmental impact.Take an enterprise in Sichuan as an example,bases on the actual production data of two periods respectively with domestic general level and advanced level,the environmental effect of multicrystalline wafer production can be quantitatively calculated by using LCA method which includes classification,characterization,and quantization.The results show that,the domestic advanced level has ahigher utilization of resources and energy compared to the general level,and it reduces emissions of pollutants,especially in dust emissions,acidification potentials,global warming potentials and ozone depletion potentials.The methods of energy conservation of domestic multicrystalline wafer enterprises are using clean energy,improving the utilization of circulating water and ingot process,increasing the grain size in the ingot,as well as using clean materials which has less environmental pollutant emissions.关键词
