Foldable Solar Panels
Solar panels are made of photovoltaic (PV) cells that are usually composed of silicon, a chemical element commonly found in sand. The process of manufacturing solar panels involves melting and purifying the silicon to create ingots, which are then sliced into wafers. These wafers are treated with various chemicals to enhance their photovoltaic properties, and then assembled into solar cells. The solar cells are interconnected and encapsulated with a protective layer to form a solar panel. The protective layer, known as a backsheet, is usually made of polymer or glass, and the frame is typically made of aluminum or steel. Some panels also include additional layers for increased energy efficiency or durability.
