I. Overview of Solar Panels Solar panels are a form of renewable energy that have been around since the early 1900s. They work by using light from the sun to create electricity, and they can be used in residential or commercial settings. Solar panels are becoming increasingly popular as an alternative source of energy, due to their efficiency ...
In this process, a seed crystal of silicon is dipped into melted silicon. As the seed crystal is withdrawn and rotated, a cylindrical ingot of silicon is formed. Figure 1: Making a Wafer from a Silicon Ingot. The silicon wafer is doped to create the PN junction structure. The n region is much thinner than the p region to permit light penetration.
