This interactive Flash tutorial shows how photovoltaic cells in solar panels convert sunlight into electrical current. It provides a close-up look at each layer of the basic solar panel, with particular emphasis on how electrons cross over the junction that joins the two silicon layers in the cell. When the concentration of negative and positive charge between the two layers reaches equilibrium, an electric field is produced -- the solar cell is ready to capture photons.

4. The Physical Setting

4B. The Earth
  • 9-12: 4B/H8. The earth has many natural resources of great importance to human life. Some are readily renewable, some are renewable only at great cost, and some are not renewable at all.
4D. The Structure of Matter
  • 9-12: 4D/H1. Atoms are made of a positively charged nucleus surrounded by negatively charged electrons. The nucleus is a tiny fraction of the volume of an atom but makes up almost all of its mass. The nucleus is composed of protons and neutrons which have roughly the same mass but differ in that protons are positively charged while neutrons have no electric charge.
  • 9-12: 4D/H9b. Some atoms and molecules are highly effective in encouraging the interaction of others.
4E. Energy Transformations
  • 9-12: 4E/H7. Thermal energy in a system is associated with the disordered motions of its atoms or molecules. Gravitational energy is associated with the separation of mutually attracting masses. Electrical potential energy is associated with the separation of mutually attracting or repelling charges.
4G. Forces of Nature
  • 6-8: 4G/M4. Electrical circuits require a complete loop through which an electrical current can pass.
  • 9-12: 4G/H4ab. In many conducting materials, such as metals, some of the electrons are not firmly held by the nuclei of the atoms that make up the material. In these materials, applied electric forces can cause the electrons to move through the material, producing an electric current. In insulating materials, such as glass, the electrons are held more firmly, making it nearly impossible to produce an electric current in those materials.

Topic: Conservation of Energy
Unit Title: Renewable Energy Sources

How does a solar panel convert sunlight into electrical current? This interactive Flash tutorial provides a close-up look at each layer of the basic solar panel to show how electrons are energized when sunlight strikes the cell.
