Which type of energy is converted into electrical energy by a solar cell?

• A. Magnetic energy
• B. Light energy
• C. Thermal energy
• D. Wind energy

Answer: (B)

Solar cells convert light energy into electrical energy through the photovoltaic effect. When light, specifically photons, strikes the surface of a solar cell, it can excite electrons from their atomic orbits in the semiconductor material, typically silicon. This movement of electrons generates an electric current.

The photovoltaic process makes solar cells a vital component in harnessing solar power, allowing the conversion of abundant sunlight into usable electrical energy for various applications. Other forms of energy mentioned, such as magnetic, thermal, and wind energy, do not directly convert into electrical energy through the mechanism utilized by solar cells. Each of these energy types involves different processes and technologies for conversion into electricity.
