How do PV cells convert radiant energy into electricity.?

Question

im doing a science final and i need to know how PV cells convert radiant energy into electricity. thanks.

Answer 1

1. Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon.

   2. Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. The complementary positive charges that are also created (like bubbles) are called holes and flow in the direction opposite of the electrons in a silicon solar panel.

   3. An array of solar panels converts solar energy into a usable amount of direct current (DC) electricity.
