Let's visualize the photoelectric effect process through a typical photovoltaic schematic: When photons hit the panel, they create electron-hole pairs. The electric field at the p-n junction then drives these charges apart - that's your DC electricity starting to flow. . The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. The photovoltaic effect was first. . I'm going to use some solar panel diagrams to show you how solar cells work and then describe all of the elements that go up to make a complete home solar system. Learn how sunlight becomes electricity and why panel efficiency matters today.
