How is Solar Energy Converted to Electricity?

When we install solar panels, we are harnessing light energy from the sun. When the light strikes the surface of the semiconductor material, a reaction takes place, which converts the light energy into electrical energy. But since solar panels aren''t 100% efficient, some of this light energy becomes heat.
