How does solar technology work?

In a PV cell, the sunlight puts electrons in movement to directly produce electricity. The main component of the PV cell is the semiconductor. The electrons in the semiconductor are charged by sunlight and move to their corresponding electrode – producing an electrical current. CSP systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam that heats up molten salt to create steam to drive a turbine that produces electrical power.
