Why are solar panels sensitive to temperature changes?

When sunlight strikes a solar panel, it generates direct current (DC) electricity through the photovoltaic (PV) effect. However, solar cells are sensitive to temperature changes, and this sensitivity is primarily attributed to two key factors: the temperature coefficient of voltage and the temperature coefficient of power.

Do solar panels produce more energy if the temperature rises?

While sunny warm days seem to be best for solar energy generation, silicon PV panels can become slightly less efficient as their temperature rises. This is due to a property of the silicon semiconductor, which means that these class of Solar PV panels have a ‘negative coefficient of temperature’: this means they produce less energy when really hot.
