How to Make Solar Cells
Solar cells convert the sun's energy into electricity, similar to the
way plants convert the sun's energy into food through photosynthesis.
Solar cells work by using the sun's energy to enable electrons in
semiconducting materials to move from orbits close to the nuclei of
their atoms to higher orbits where they can conduct electricity.
Commercial solar cells use silicon as the semiconductor, but here is a
way to make a solar cell with more accessible materials to see for
yourself how it works.
