You have come across some evidence that the average efficiency of phovotaic cells made from Monocrystalline Silicon is less than that of Multijunction Gallium Arsenide cells. So, you request a sample of each from the manufacturer to test. How would you go about gaining insight whether (or not) the Multijunction Gallium Arsenide cells are more efficient than the Monocrystalline Silicon? Be very specific about your sample and design.
