The photoelectric effect, in which light striking certain materials causes them to emit electrons, forms the basic scientific principle behind which everyday technology?

Explanation

The photoelectric effect describes the phenomenon in which light striking certain materials, typically metals or semiconductors, causes electrons to be emitted or dislodged, generating an electric current in the process. This principle forms the fundamental scientific basis for solar cells, which convert light energy into electrical energy by capturing electrons freed when sunlight strikes the semiconductor material inside the panel. The photoelectric effect was theoretically explained by Albert Einstein in 1905, a contribution that later earned him the Nobel Prize in Physics.
