Temperature coefficient of maximum power The most widely used temperature coefficient in performance studies of PV modules is the maximum power (P MAX) temperature coefficient, γ. This value is used to correct module power to the STC level and calculate the temperature corrected performance ratio.
The temperature coefficient of a solar cell is the amount by which its output voltage, current, or power changes due to a physical change in the ambient temperature conditions surrounding it, and before the array has begun to warm up.
Since the PV cell parameters (V oc , J sc , FF) usually vary linearly with temperature, it is possible to separate the temperature sensitivity of a device performance into the sum of their temperature coefficients:
The efficiency of photovoltaic conversion is fundamentally dependent upon the converter temperature. This temperature dependence is negative and its magnitude depends upon the bandgap of the PV device. In general, solar cells made of larger bandgap semiconductors have lower temperature sensitivities.
As a pv cell’s voltage is directly affected by its operating temperature. The electrical operating characteristics of a particular photovoltaic panel or module, given by the manufacturer, is when the panel is operating at an ambient temperature of 25 C. But the open-circuit voltage of a pv panel will increase as the panels temperature decreases.
This leads to a negative temperature sensitivity of the absorption–emission rate balance that is the origin of the temperature behavior of PV cells and explains why all PV devices become less efficient as they heat up.
