How does temperature affect the output efficiency of a solar cell?

In general, taking the temperature rise into consideration, output efficiency of a solar cell drops remarkably especially for the CPV system if the heat generation is not well dissipated, reducing both the output photocurrent density and the output voltage. 4. Effects of cells' parameters on the loss processes

How does cooling capability affect the efficiency of a solar cell?

The cooling capability affects the value of the short circuit current (Isc) and open-circuit voltage (Voc). Isc and Voc values affect the efficiency of the solar cell. Moreover, the copper-copper material has the lowest temperature, which affects the resulting Voc and Isc values. The lower the temperature value, the higher the Voc and Isc values.
