Do Photovoltaic Panels Absorb Natural Light? The Science Behind Solar Energy Conversion
You know, when people see dark solar panels glistening under the sun, they often wonder: "Do these things absorb natural light, or is it just heat that makes them work?" Let's cut through the confusion. Photovoltaic (PV) panels primarily convert sunlight – not ambient heat – into electricity through the photoelectric effect . Here's the kicker: while they do absorb photons from natural light, excessive heat can actually reduce their efficiency by 10-25% .
