"Haifa SILICA Photovoltaic – PV - 100" - Silica Sand for manufacturing photovoltaic (PV) glass
Solar-grade silica sand should have high silica content, typically above 99.5% or even higher. This ensures that the glass produced has excellent transparency and minimal impurities that could affect the performance of solar panels.
Iron impurities can cause discoloration and reduce the efficiency of PV glass. Therefore, solar-grade silica sand needs to have a very low iron content, usually less than 100 parts per million (ppm).
The particle size distribution of the silica sand is important for achieving uniform glass quality. Specific size ranges are often required based on the manufacturing process. The sand may undergo processes like washing, sieving, and grading to achieve the desired particle size distribution.
Apart from iron, other impurities like aluminum, titanium, and boron should be minimized to maintain the desired electrical and optical properties of the PV glass.
