The process of the production of multi-crystalline silicon is also that of incessant purification of metallurgical grade silicon, during which high energy consumption and environmental pollutants are inevitable. The paper, which is based on life cycle assessment (LCA), presents calculation and analysis on resource input, energy consumption, emissions into and comprehensive impact on environment generated...
A life cycle assessment (LCA) has been performed for the grid-connected electricity generation from a metallurgical route multi-crystalline silicon (multi-Si) photovoltaic (PV) system in China. The energy payback time (EPBT), environmental impacts and total environmental impact indexes were calculated. Based on the contribution analysis, it can find out the most critical stage (or process) and the...
