Homemade Photovoltaics - DIY Silicon PN Junction Solar Cell Testing

From a channel Lumen includes in full: Sam Zeloof built a semiconductor fab in his garage and documents the processes (photolithography, vacuum, thin films, electron microscopy) with real results; the Semiconductor Fabrication Basics series is a rare hands-on course.

A 12-minute video from Sam Zeloof's catalogue; the title names its topic.
