Deep Dive: E6F01
The correct answer is C: Electrons. What absorbs the energy from light falling on a photovoltaic cell is electrons. Electrons in the semiconductor absorb photons and create current. For amateur radio operators, this is important for photovoltaic knowledge. Understanding this helps when working with solar cells.
Why Other Answers Are Wrong
Option A (Protons): Incorrect. Protons don't absorb the energy - electrons do. Protons isn't the answer. Option B (Photons): Incorrect. Photons are the light particles, not what absorbs energy - electrons absorb the energy. Photons isn't the answer. Option D (Holes): Incorrect. Holes don't directly absorb the energy - electrons do. Holes isn't the answer.
Exam Tip
Photovoltaic cell energy absorption = electrons. Think 'P'hotovoltaic = 'E'lectrons absorb 'P'hotons. Electrons in the semiconductor absorb photons and create current. Not protons, not photons (the light), not holes - just electrons.
Memory Aid
Photovoltaic cell energy absorption = electrons. Think 'P'hotovoltaic = 'E'lectrons. Electrons in the semiconductor absorb photons and create current. Important for photovoltaic knowledge.
Real-World Example
A photovoltaic cell: Electrons absorb the energy from light falling on it. When photons hit the cell, electrons in the semiconductor material absorb the energy and are excited, creating current. This is what absorbs the energy - electrons.
