How Solar Panels Work
Solar Cells convert sunlight directly into electricity. They start of as sand, which is processed into highly purified silicon, in a process called 'doping' small amounts of special impurities are added into the purified Silicon. When Silicon is 'doped' with Boron the resulting material is called 'P-type' and if Silicon is 'doped' with Phosphorus the resulting material is called 'N-type'. The 'P-type' material is negative and the 'N-type' material is positive.
When Silicone is 'doped' with both Boron and Phosphorus in just the right way, a 'P-injunction' is formed. This process establishes a permanent electric field in the crystal. The 'P-injunction' is made so that light can strike its top surface, metal conductors are attached to the 'P' and 'N' type sides. When sunlight strikes the solar cells, electrons are ejected from the atoms and the permanent electric field in the junction, steers them to the 'N-type' side. If a wire connects both sides of the solar cell then electric current can flow whenever sunlight strikes the solar cell.
