About the Science
- A very clear visual and verbal explanation of how a PV panel works. Discusses light as a photon.
- Comments from expert scientist:
- A good non-scientific introduction to the topic. Not much has changed since it was made, so still accurate.
- The video is clear, interesting and has high production values
- This resource ducks the hard-to-explain question of why the electrons flow in the direction they go to develop a voltage, instead of in both directions.
- This resource was made before photovoltaics became and energy-significant (>1%) source of electricity in the U.S. and worldwide, so it is not actually optimistic enough about the potential.
About the Pedagogy
- The main message of the video is that PV systems generate power without pollution as they convert the sun's energy into electricity.

Disciplinary Core Ideas: 3
HS-PS3.D3:Solar cells are human-made devices that likewise capture the sun’s energy and produce electrical energy.
HS-PS4.B1:Electromagnetic radiation (e.g., radio, microwaves, light) can be modeled as a wave of changing electric and magnetic fields or as particles called photons. The wave model is useful for explaining many features of electromagnetic radiation, and the particle model explains other features.
HS-PS4.B3:Photoelectric materials emit electrons when they absorb light of a high-enough frequency
