Silicon is one of Earth’s most abundant elements. Yet demand for the pricey high-purity form of silicon required to make solar cells has risen with the growth of the solar photovoltaic industry. This, together with limitations of the energy-intensive technology customarily used to produce solar-grade silicon, has led many to think about the development of improved technologies for producing solar- grade silicon and using materials other than silicon for solar cells. Investigate means for producing solar cells using silicon, including conventional and improved methods, and for producing cells using other materials. Compare and critically evaluate all methods discovered based on energy use, environmental impact, and cost. Prepare a poster presentation of your findings.
