Imagine you are testing a solar cell in your lab. You irradiate the solar cell with photonsfrom an Ar ion laser. The laser output is 532 nm light at 5.0 W power (1 W = 1 J/s), and the diameter of the laser beam is 5 mm. Assuming the laser beam is the only light source incident on the solar cell, and that each photon incident on the solar cell surface produces one electron coming out of the cell, what current, I(in A),would you measure under these irradiation conditions? (1 A = 1 C/s; the charge of one electron e= 1.602 x 10-19C).[hint: how many photons per second strike the surface of the solar cell?]
