This video introduces photovoltaic energy resources and the related science and engineering research conducted at the National Renewable Energy Laboratory (NREL).
The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials
Video is closed captioned.
Functionality of watching video in full-screen mode didn't work.
Written text of the script is available from the website.
The video is embedded into the NREL page on learning about photovoltaics.
A variety of scientists and engineers are featured and specific terms are well explained.
A good introductory video to Photovoltaic and a lead into a solar or renewable energy unit.
Most of the video footage is from the NREL laboratories and features scientists who are actively involved in research and development of photovoltaic systems.
Comments from expert scientist: Though Silicon is the second most abundant material on earth, it is not cheap to be purified. So although abundant silicon solar cells are cheap to produce.
Use this video and the other information on the NREL site as a starting point for student research on different renewable energy technologies.
