Question- Assume that most of the electromagnetic energy from the sun is the visible region near 500 nm. Calculate the maximum value of the work function for a metal to be used in photovoltaic cells to convert solar energy into electicity.
Then identify which of the following metals could be used in such a capacity:
• silver (phi) = 7.59 x 10-19 J
• silicon (phi) = 7.24 x 10-19 J
• tungsten (phi) = 7.20 x 10-19 J
• titanium (phi) = 6.94 x 10-19 J
• barium (phi) = 4.29 x 10-19 J
• potassium (phi) = 3.78 x 10-19 J
