Use the photo diode equation (25.17)

to compute I_photo/I₀ for a silicon solar cell with V_oc = 0.7 V. Write the power as a function of voltage and compute the fill factor, the maximum power IV attainable as a fraction of I_photoV_oc. Repeat the calculation for cells with V_oc = 0.5 and 0.86 V and compute the maximum efficiency of a single-junction silicon photocell in these cases.
