SUMMARY

The fill factor (FF) of a solar cell is calculated using the formula FF = (Vm * Im) / (Voc * Isc), where Vm is the maximum voltage, Im is the maximum current, Voc is the open-circuit voltage, and Isc is the short-circuit current. The discussion highlights confusion regarding the derivation of a logarithmic relation mentioned in a textbook example. Participants are encouraged to clarify the source of this Ln relation and its relevance to the fill factor calculation.

Homework Statement: a question about the fill factor of a solar cell

Relevant Equations: FF = Vm*Im/Voc*Isc

hi guys
for a solar cell i know that the fill factor is given by the following relation :
$$ FF = \frac{Vm*Im}{Voc*Isc}$$
but when solving the following example :
