Purification And Characterization Of SiO2 Based Quartz Sand

Solar cells are an environmentally friendly energy conversion tool. This equipment utilizes solar energy so that its effectiveness depends on the amount of sunlight intensity. The solar cell industry is an alternative source of renewables. This industry utilizes silica sand as its base material.

China and Indonesia has natural wealth of silica sand. Silica sand reserves with high concentrations are a support for the development of advanced materials. Mastery in advanced technology material, one of the main hope in framework of independence of the community to provide the raw materials of solar cell.

The technology material for solar cell have experienced a rapid progress in developing. In the past years, a few silicon purifying industries had started producing the silicon as the material especially to be applied for the solar cell system by looking at the development of the silicon production for solar cell, as well as the projection of the solar cell marketing in the future

Today, silicon solar cell (first generation) is still dominating the marketing world which is about 80% . The third generation of the solar cell like dye-sensitized solar cell, organic photovoltaic, and others are still under a research phase and haven’t entered the mass production phase yet .

Quartz sand contains crystals of silica (SiO2) as well as sedimentary materials that carry over the settling process. Quartz sand or white sand is the result of weathering rocks containing major minerals, such as quartz and rock ore. Quartz sand as a result of weathering that is naturally washed and carried by water or wind and settles on the banks of a river, lake, or sea. The content of silica in sand is at least 97-98%.

This content depends on the mineralogical characteristics of the original silica sand deposit. The physical properties of silica sand minerals are the specific gravity, magnetism, and electricity. With the overflowing of the spare silica sand in Indonesia, it gives a huge opportunity for the development of the national industry.

The solar cell industry that is being referred to is the industry that has the independence in providing their raw materials for their production. In Hengyang Industry, the purifying of the white sand silica sand have been done by using the purification method.
