Question

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^2

Calculator power consumption = 0.2 mW

AM1.5 at 1000 Wm^-2 is 3 x 10^21 photons m^-2 s^-1

Average energy of each photon is 2eV which is

2 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.
