It all starts with silicon crystals. The silicon metal needs to be mined then purified in an electric furnace. Pure cylinders, or ingots of silicon are then thinly sliced into rectangles that will fit a solar panel perfectly. The silicon is treated with both boron and phosphorus, resulting in a positive and negative charged semiconductors. Wires are then connected, creating a path for the electricity to power your home.
At this point, the cells are coated with an anti-reflective substance so that sunlight can be absorbed, rather than reflected, as much as possible.
