The development of renewable energy is becoming a crucial aspect because fossil fuels are non-renewable energy and will runout in the near future. Since Indonesia is in the equator area which gets sunshine throughout the year, solar cell is one of therenewable energy which is very promising as renewable energy. The obstacle to develop solar cell is the high cost of solar panel. Therefore, new technology to produce silica with high purity is important to be performed in order to be used as material inmaking solar panels. Here we fabricated high purity silica precipitates from quartz sands from Kendawangan, WestKalimantan. We fabricated silica precipitated by roasting quartz sand and then dissolving the sodium silicate into boilingwater followed by leaching, precipitation and repeatedly washing using hydrochloric acid. The content of SiO2 of atomicabsorption spectroscopy of quartz sand from Kendawangan contains SiO2 of 99.2% and the remaining trace elements areimpurities. The roasting process was conducted using sodium carbonate with the comparison of quartz sand: sodiumcarbonate = 55:45 (% ratio) at 1.200 °C for 2 hours obtaining sodium silicate crystal. The final result of silica precipitatesobtained in this research showed that the silica precipitates has very high purity with content of SiO2 up to 99.99%. Thissuccessful result will contribute for domestic industry which can provide high purity silica precipitates for material source ofsolar grade silicon in photovoltaic device.
