A silicon solar cell behaves like a battery with a 0.40 V terminal voltage. Suppose that 1.0 W of light of wavelength 610 nm falls on a solar cell and that 50% of the photons give their energy to charge carriers, creating a current. (1) What is the solar cell's efficiency-that is, what percentage of the energy incident on the cell is converted to electric energy?

Types of Charge Carriers

A carrier is a type of object which carries a particular thing from one point to another point. For instance, people use different vehicles from one place to another, and the vehicle carries those people and acts as a carrier.
