3. The power output of a solar cell varies with the voltage it puts out. The voltage Vmp at which the output power is maximum is given by the equation: q V, 1 kaT Where Voc is the open circuit voltage, Tis the temperature in Kelvin, q 19 is the charge on an electron, and kB 1.3806* 10 23 Jlk is Boltzmann's constant. For V 30.5V and room temperature (T 3297 K), determine the voltage Vmp at which the power output of the solar cell is a maximum. Write a program in a script file that uses the fixed-point iteration method to find the root. For starting point, use V 0.5 V. To terminate the iterations, use (Lecture #4 Eq. (3.18) with E 0.001
