Discussion on Environment Impact Assessment in the Lifecycle of PV Systems

摘要

This paper, taking the crystalline silicon PV power generation system for example, discussed environmental impact assessments of 3 main stages in PV system lifecycle including "manufacture", "use" and "disposal". "Manufacture" stage focused on pollutant generation and discharge coefficient measurement of 4 productive processes in the crystalline Si cell industry chain; In "use" stage, the climate and environment impact assessment of large-scale PV plant was discussed. In addition, "Disposal" stage introduced the technology development and environment evaluation of PV system recycling and safety disposal.
