Introduction to the Photovoltaic Effect
Four engaging lessons introduce scholars to the photovoltaic effect, solar cells, and electricity. After learning related vocabulary, pupils watch a video to learn why silicon is often used as a photoelectric semiconductor and how solar cells create an electric current. The second installment of the Solar Resources Assessment unit looks at macro-scale photovoltaic (PV) technology. Class members then set up and use Solar Pathfinders to take measurements related to solar insolation and conduct site assessments for possible spots on school grounds to place a solar module.
