1) I need to know how much power is generated from a solar cell at AM1.5?2) When used indoors the available power from the solar cell may reduce by a factor of 1000. Calculate the shortfall in power generation needed for the calculator if the power output of the solar cell is reduced by this amount?From the text book provided:Cell dimension = 1.5 x 3.5 cm^2Calculator power consumption = 0.2 mWAM1.5 at 1000 Wm^-2 is 3 x 10^21 photons m^-2 s^-1Average energy of each photon is 2eV which is2 x (1.6 x 10^-19) joules.I need to show all working out. If any more information is needed please let me know I have the text book.
