Why all solar panels are secretly LEDs (and all LEDs are secretly solar panels)

Cited as a neat demonstration that diodes work in both directions in semiconductor and LED discussions.

Steve Mould shows that LEDs and solar panels are both diodes made from semiconductors, so a solar panel can emit light and an LED can generate electricity. He demonstrates a small solar panel lighting up.

“Steve Mould had a video[1] about this a couple of years ago where he shows a small solar panel lighting up.” (HN, 2022)
