Answer:
D
Solution:
A solar cell is a semiconductor device that converts light energy directly into electrical energy.
When photons of light fall on the p-n junction of the solar cell, they impart energy to the electrons, creating electron-hole pairs. The built-in electric field of the junction separates these charge carriers, generating a potential difference across the terminals.
This phenomenon of generating a voltage or electric current in a material upon exposure to light is known as the photovoltaic effect.
Thus, a solar cell works on the principle of photovoltaic conversion.
