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 \(mA/cm^2\)). ______

Calculate the efficiency (in %): ______

A solar cell with dimensions 12cm x 12cm is illuminated at standard test conditions. The cell presents the following external parameters:\(V_{oc} = 0.8V,\, I_{sc} = 3A,\, V_{mp}=0.75V,\, I_{mp}=2.5A\) Calculate the fill factor (in %): ______

The power output of a solar module at STC is \(250Wp\) with an area of \(2m^{2}\), while the spectrum provides \(1000W/m^{2}\) under STC. What is the total efficiency of the module in %? How much radiation power does the module receive in watts (W)? ______
