Spottyfox斑狐狸@rey Wait, what?!
@spottyfox which part
@rey The solar panel - LED part, had no idea
@spottyfox so they're basically the same: semiconductor junctions that deal with photons. if you apply enough light to a LED, it'll produce a voltage. if you apply enough voltage to a solar panel, it'll emit light. neither do a good job of doing the wrong thing, but they do

@rey @spottyfox the light of typical solar panels is infrared too so you need an infrared camera to see it (i think phones also work?)
H3@charlotte @spottyfox @rey a solar panel lifehack i saw on a youtube channel (bigclivetv if i remember correctly) was applying power to a solar panel, then looking at it with your phone to see which parts of the panel have failed (not lighting up)
@h3 @spottyfox @rey i think it relies on phone camera lenses having poor IR filtering, which phones with better cameras may improve on, but iirc solar panels and the LEDs in remotes use the same semiconductor alloy (pure silicon)
@charlotte @spottyfox @rey yeah. u can also just aquire a cheap shitty webcam and scrape/smash the glass IR filter out of it
