Effect of Temperature
The above equation shows that the temperature sensitivity of a solar cell depends on the open-circuit voltage of the solar cell, with higher voltage solar cells being less affected by temperature. For silicon, E G0 is 1.2, and using γ as 3 gives a reduction in the open-circuit voltage of about 2.2 mV/°C;
