John decides to connect two of these modules with a cable in series. This results in an additional \(2 m\Omega\) series resistance loss. What is the new fill factor (in %)? (Hint: use the voltage drop at the maximum power point). ______

What is the efficiency of the module (in %)? ______

John determined that the maximum power he could get out of this module is 19.5 W. Calculate the fill factor of the module (in %). ______

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 \(25 ^oC\), the incident spectrum is the AM1.5 spectrum and the incident power density is \(1000 W/m^2\). The result is illustrated in the figure below. Calculate the short-circuit current density (in \(mA/cm^2\)). ______
