(a) Using the current-voltage characteristics of the solar cell described in problem 1.60, determine \(V_{D}\) when \(I_{D}=0.8 I_{S C}\).

(b) Using the results of part (a), determine the power supplied by the solar cell.

Data From Problem 1.60:-

The output current of a pn junction diode used as a solar cell can be given by \[I_{D}=0.2-5 \times 10^{-14}\left[\exp \left(\frac{V_{D}}{V_{T}}\right)-1\right] \quad \mathrm{A}\]
The short-circuit current is defined as \(I_{S C}=I_{D}\) when \(V_{D}=0\) and the opencircuit voltage is defined as \(V_{O C}=V_{D}\) when \(I_{D}=0\). Find the values of \(I_{S C}\) and \(V_{O C}\).
