Can we use aluminum to make solar panels?

Yes, aluminum is indeed used in the production of solar panels. It is primarily employed as a component of the frame that supports and protects the panel. Aluminum's light weight, high strength, and corrosion resistance make it an ideal material for this purpose. Additionally, aluminum can be used in the backsheet of the solar panel, providing structural support and helping to protect the panel from environmental factors. However, aluminum is not used in the actual photovoltaic cells that convert sunlight into electricity; those are typically made from silicon.
