This process involves the fabrication of PV cells, which are made up of semiconductor materials such as silicon. While some concentrating solar-thermal manufacturing exists, most solar manufacturing in the United States is related to photovoltaic (PV) systems. Solar energy can be captured using two primary methods: Photovoltaic (PV) System: This. . The process of producing high-quality silicon involves two critical steps: purification and ingot growth. This transformation occurs through the photovoltaic effect, discovered in 1839 by Alexandre Edmond Becquerel, which enables solar cells to generate electrical current when exposed to. . Purified quartz is processed into solar-grade silicon, then grown into ingots and sliced into wafers (with M10 and G12 now mainstream). Key steps include: How well these processes are controlled. .
