Perhaps thanks to YouTube, more people understand that light emitting diodes (LEDs) and solar cells may be thought of as mirror images of one another because the conversion of energy in each involves similar interactions of charge carriers. It’s easy to find YouTubers who have either created solar arrays from LEDs or rigged solar cells […]
