FAQs about Can solar cells be used as lights
Can light be used to power a solar cell?
If light is strong enough to be visible, that means it is strong enough to power a solar cell. Any artificial light, from fluorescent ballasts to incandescent bulbs, can give off some kind of light that is able to be absorbed and used by solar cells. However, there are two caveats to this fact:
