The Physical Reason for Why Overheating Lowers Solar Panel Efficiency

“Why does physics dictate that overheated solar panels will have lower efficiencies?”

The amount of solar energy that can be created by a solar panel is dependent on the difference in voltage between the electrons at the rest state and the activated state. However, as a solar panel becomes hotter, the rest state will be pushed outwards while the active state will be held constant. This results in a decrease in voltage and by extension power output. This is The Physical Reason for Why Overheating Lowers Solar Panel Efficiency.
