Aluminum is not typically used to make solar cells due to its properties. Solar cells are usually made from materials like silicon, which is a semiconductor and can efficiently convert sunlight into electricity. Aluminum, being a good conductor, is used in the manufacturing process of solar cells for its electrical conductivity, but not as the active material that generates electricity. It is used in the form of aluminum paste in the back surface field of solar cells to create a conductive layer and in the frame to provide structural support. However, for the photovoltaic conversion process itself, other materials are more suitable.
