WebFeb 3, 2024 · Large amounts of hazardous diamond-wire saw powder (DWSP) waste were generated in the photovoltaic (PV) industry, which not only wasted the valuable resources but also polluted the environment and harmed the human health. WebApr 11, 2024 · Silicon wafer slicing is a crucial process during solar cell fabrication, but it often stains the silicon wafer surface. Thus, this work systematically investigated the composition, source, and cleaning method of typical white spot stains on silicon wafer surfaces. The EDS and XPS results showed that the white spot stains contained CaCO3 … WebA new strategy for de-oxidation of diamond-wire sawing silicon waste via the synergistic effect of magnesium thermal reduction and hydrochloric acid leaching.
