“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.
