These cookies are then subjected to various processes, such as stamping and welding, to create the final can structure. The lids, or top cookies, are equipped with overhangs designed for easy sealing, often using a method known as double seaming. This ensures that the cans not only retain their contents but also withstand the rigors of shipping and storage.

Welding is another critical step in the manufacturing process, where pieces are fused together to create a sturdy structure. Factories today have upgraded their welding techniques, utilizing robotic welders for consistency and strength. After assembly, the metal surfaces undergo cleaning and priming to prepare for painting, which protects against rust and enhances appearance. Finally, drawers are added, and the entire unit is subjected to quality control checks to ensure durability and functionality.

Semiconductor materials, such as silicon, gallium arsenide, and cadmium telluride, are commonly employed in the manufacturing of solar cells. Each material has a specific bandgap that dictates its efficiency in converting sunlight into electricity. Silicon, for example, has a bandgap of about 1.1 eV, which allows it to effectively utilize a significant portion of the solar spectrum. However, while silicon-based solar cells dominate the market due to their cost-effectiveness, they often operate at efficiencies around 15-22% in real-world conditions.
