Diamond wire saw silicon powder
WebOct 6, 2024 · A diamond wire saw is employed when crystalline silicon is to be cut into wafers for the fabrication of silicon-primarily based photovoltaic cells. Around one-third of the silicon is lost throughout this process, which amounts to approximately 0.3 million tons of DWSSP waste era per annum. WebAbstract Improving the effective utilization of diamond wire saw silicon powder (DWSSP) waste is beneficial to increasing the production profit of the photovoltaic (PV) industry. It is also important to reduce the emissions of DWSSP to control environmental pollution.
