Producing electricity from light involves the use of particles called ____.

Producing electricity from light involves the use of particles called ____.

• A. Electrons
• B. Photons
• C. Protons
• D. Neutrons

Answer: (B)

Light provides energy in discrete packets called photons. When light shines on a solar cell, photons are absorbed by the semiconductor and transfer their energy to electrons, enabling them to move and be collected as electric current. In this context, photons are the particles of light responsible for producing electricity. The actual moving charges in the circuit are electrons, but they’re driven by the energy delivered by photons. Protons and neutrons are parts of atomic nuclei and don’t play a direct role in converting light to electricity.
