Answer:
The two concepts Photoelectric effect and Photovoltaic effect explain how substances react upon the exposure to light. Photoelectric effect describes the emission of electrons from the surface of a substance in response to incident light. Metals often show this property. Photovoltaic effect is the process in which two dissimilar materials in close contact produce an electrical voltage when struck by light. The main difference between Photoelectric Effect and Photovoltaic Effect is that the electrons in Photoelectric Effect are emitted to open space whereas the electrons in Photovoltaic Effect enter a different material.
