Photoelectric Effect vs. Photovoltaic Effect: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 16, 2023
Photoelectric effect: ejection of electrons by light. Photovoltaic effect: electricity generation by light.

Key Differences

The photoelectric effect involves the ejection of electrons from a material when light hits it, typically observed in metals. Conversely, the photovoltaic effect refers to the creation of voltage or electric current in a material upon exposure to light, usually in semiconductors.
