Question: 1 / 400

What is the function of a "Solar cell"?

a. The sun with the celestial bodies that revolve around it in its gravitational field

b. Air pollution by a mixture of smoke and fog

c. A developed ovule consisting of a protective coat stored food and an embryo

d. A cell that converts solar energy into electrical energy

A solar cell functions by converting solar energy, which comes from sunlight, into electrical energy. This process relies on the photovoltaic effect, where certain materials, typically semiconductors like silicon, absorb photons from sunlight and release electrons. These free electrons create an electric current, which can then be harnessed for power.

The other options relate to entirely different concepts. While option A discusses celestial bodies, it does not pertain to energy conversion. Option B addresses air pollution, which is unrelated to solar technologies. Lastly, option C describes the characteristics of an ovule, which is a part of plant reproduction. None of these options connect to the primary function of a solar cell, which is specifically designed for converting light into electricity.
