Why is silicon used for making solar cells?
Silicon is very often used in solar panels as a semiconductor because it is a cost-efficient material that offers good energy efficiency. Other than that it has high corrosion resistance, long-term durability, optimal thermal expansion properties, good photoconductivity,
How are solar panels made?
Silicone can''t be used in this form to make solar panels. So next, the silicon boules are sliced into thin discs or wafers. These wafers are often cut into hexagonal shapes to minimise waste, although this can increase costs. Since pure silicon is shiny and reflective, which isn''t ideal for solar panels, a non-reflective film is added to
