Environmental Effects of Technological Improvements in Polysilicon Photovoltaic Systems in China—A Life Cycle Assessment

Due to increasing pollution and the overexploitation of traditional energy, there is both an environmental a resource threat sustainable development. China’s government prioritizes optimization structures with photovoltaic industrial support policies address potential hazards traditionally highly polluting energy resources. However, applying green resources not panacea for solving existing as problems cannot be solved level optimized types. Instead, it necessary further explore carbon emissions from clean Therefore, we construct polysilicon PV system’s whole life cycle emission model by LCA method building coefficient model. More specifically, divided into six components calculated each part separately. In addition, applied case analysis method. We analyzed 280 MW solar cell production project leading global module company in China. The research results indicated that companies should proactively develop advanced technologies upgrade energy-saving safety measures reduce consumption raw materials final disposal process.
