photovoltaic effect, photovoltaic process
The phenomenon that occurs when photons (the "particles" in a beam of light) strike electrons and free them from their bound position.

When this property of light is combined with the properties of semiconductors, electrons flow in one direction across a junction, setting up a voltage.

With the addition of circuitry, current flows and electric power is available.

photovoltaic effect
The phenomenon that occurs when photons, the "particles" in a beam of light, knock electrons loose from the atoms they strike.

When this property of light is combined with the properties of semiconductors, electrons flow in one direction across a junction, setting up a voltage.

With the addition of circuitry, current will flow and electric power will be available.
