John has used a solar simulator setup to measure the relation between the voltage and the current of a small photovoltaic module (40 cm long and 40 cm wide). The measurement setup maintains the standard measurement conditions: the temperature is controlled to 25oC, the incident spectrum is the AM1.5 spectrum and the incident power density is 1000W/m2.
John decides to connect two of these modules with a cable in series. This results in an additional 2 milli-ohms; series resistance loss. What is the new fill factor (in %)? (Hint: use the voltage drop at the maximum power point).
