SUMMARY
The production of photovoltaic cells involves several key steps, including the purification of silicon, the creation of silicon wafers, and the application of anti-reflective coatings. The process begins with metallurgical-grade silicon, which is purified to produce solar-grade silicon. This silicon is then sliced into thin wafers, typically around 180 micrometers thick, and treated to enhance light absorption. Finally, the wafers are coated with materials such as silicon nitride to reduce reflection and improve efficiency.
