EXTRACTION OF SILICON FROM RICE HUSK FOR SOLAR CELL FABRICATION

Abstract

In today’s world, the production of energy mainly depends on Fossil fuels, for instance, petroleum, natural gas, and natural gas. Since these fuels will soon be depleted if we continue their use at the same rate, therefore, we must switch to alternative sources such as solar energy, wind energy, or hydro energy for electrical energy generation since India has a broad scope of solar energy generation due to its geographical location so we must focus on generating it more economically as India receives a good number of sunny days, around 250 to 300 days per year ,and has 1600 – 2200 kWh/m2 of global radiation which is same as that received by the sub-tropical and tropical areas (Choi et al., 2015). This accounts for around 6000 GWh of energy annually. Various states in India have the high potential for solar energy generation like that of other countries like U.S., Japan & Europe where use of solar energy is maximum. Even if power generation from Solar Cells is a well-studied or known technology, its usage in day-to-day life is limited due to high cost of material used in its manufacturing. The main component for the manufacturing of solar cell is silicon. So, the study mainly focuses on the production of Silicon at a comparatively low cost by using the raw material i.e., rice husk which is basically the waste product of rice (Chun and Lee, 2020).
