Measure the voltage from the photovoltaic cell when it is a set distance from the light source. Repeat the experiment with different sized PV cells. Choose a range of different sized PV cells that is sufficient to give a valid conclusion. If the measurements are too close together, it is difficult to have confidence in any trend shown.
