A solar cell fabricated with a p-n junction has an open circuit voltage of 0.6V and a short circuit current of 20mA/cm²when exposed to a solar insolation of 1000 W/m², and has a form factor FF=0.7

Draw the current-voltage characteristic of this device, making sure to identify the Voc and Isc, and the point where the maximum power is generated.
What is the efficiency of this cell?
Suppose you can improve the manufacturing process of the cell so that the carrier life time is increased by 4 times. What will happen to the V_oc and I_sc of the cell? Draw how the current voltage characteristic will change.
If the solar insolation of 1000 W/m² is constant for 8 hours per day and then is zero for 16 hours per day what is the capacity factor of this cell? How much electrical energy will it produce in a day?

1. Why don’t the short circuit and open circuit voltage produce power in a p-n cell?...

1. Why don’t the short circuit and open circuit voltage produce power in a p-n cell? 2. The power supplied by a solar cell is proportional to its surface area. Using the flux of solar energy under AM1 conditions, estimate the power a 1-cm2 solar cell will yield. State explicitly any assumption you make.
