Suppose that a solar cell is placed in sunlight, where it absorbs solar radiation and outputs useful electrical energy at a rate of 200 W. This particular solar cell is made of silicon, has a mass of ~5 g, and its efficiency for converting sunlight to electrical energy is 25 %. The specific heat of silicon is 700 J/(kg k). If the solar cell is left in the sun for 10 minutes, how much energy, in the form of solar radiation, has it absorbed?
