Why do current generation solar panels only operate at ~30% efficiency? What stops us from achieving 100%?
100% efficiency would basically mean the solar panel is a black hole. Any light that hits it disappears and is entirely converted to electricity. The panel itself wouldn't get hot (because the heat is solar energy being converted into infrared), it wouldn't get worn or erode or degrade from the s…
The Short Answer
100% efficiency would basically mean the solar panel is a black hole. Any light that hits it disappears and is entirely converted to electricity. The panel itself wouldn't get hot (because the heat is solar energy being converted into infrared), it wouldn't get worn or erode or degrade from the sun, it wouldn't reflect any light, etc.
