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
- Draw the current-voltage characteristic of this device, makingsure to identify the Voc and Isc, and the point where the maximumpower is generated.
- What is the efficiency of this cell?
- 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.
- 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?
