Processing of quartz lumps rejected by silicon

2015-2-10  Although there are several processing methods to reduce impurity levels in quartz, the characteristics of the ore are extremely important for obtaining a good processed quartz powder, able to be transformed into high-quality fused silica. Some of the processing methods include acid leaching (Du et al., 2011), electrochemical treatment (Dal Martello et al., 2011), and biological leaching (Arslan and

Silicon processing: from quartz to crystalline silicon

2011-3-15  The value chain for the production of crystalline silicon solar cells has been reviewed. The primary processing steps for the production of silicon solar cells from quartz are as follows: bulk production of metallurgical-grade silicon via carbothermic reduction in a submerged furnace, refining of metallurgical-grade silicon via the chemical means to polycrystalline silicon, or through the metallurgical route to solar-grade silicon, wafer manufacturing, and, lastly, silicon solar cell manufacturing. During downstream processing, solar cells are interconnected and encapsulated into solar modules (panels), which can be used individually or incorporated into a photovoltaic system for electricity generation and supply. The cost for crystalline silicon based solar cells is approaching one US dollar per watt peak ($1/Wp), while the most cost-effective solar modules in industry have reported costs below $1/Wp, and are based on CdTe thin films. Solar cell energy conversion efficiencies as high as 22% have been reported in industry for crystalline silicon
