Electrical Engineering

A solar cellfabricated with a p-n junction has an open circuit voltage of 0.6Vand a short circuit current of 20mA/cm2when exposed to asolar insolation of 1000 W/m2, and has a form factorFF=0.7

  1. Draw the current-voltage characteristic of this device, makingsure to identify the Voc and Isc, and the point where the maximumpower is generated.
  2. What is the efficiency of this cell?
  3. Suppose you can improve the manufacturing process of the cellso that the carrier life time is increased by 4 times. What willhappen to the Voc and Isc of the cell? Drawhow the current voltage characteristic will change.
  4. If the solar insolation of 1000 W/m2 is constant for8 hours per day and then is zero for 16 hours per day what is thecapacity factor of this cell? How much electrical energy will itproduce in a day?
