We wish to use the photoelectric effect to convert light toelectrical power. A photoelectric effect test cell similar to theone shown on the right is constructed with A1 metal (work functionof ΓΒ=4.0eV) for the photoelectric cathode. Monochromatic light ofwavelength 248nm and an intensity of 100mW cm^(-2) is used to testthis new type of solar cell. The light falls on an A1 photoelectriccathode of area 1cm^(-2).
There is 0.01999 amps of electrical current flow in thesystem
2) How much electrical power may be extracted from thisdevice?
