Question

Q1) An ideal silicon solar cell (i.e. without considering resistive losses), operating at T = 300K , has the following  Open circuit voltage Voc = 800 mV, and short circuit current density 2 Jsc = 23 mA/ cm under 82.1% of the AM1.5G illumination. Open circuit voltage Voc =759 mV, and short circuit current density 2 Jsc = 8 mA/ cm under 28.6 % of the AM1.5G illumination

1.1) Calculate the short circuit current density of the cell under the full AM1.5G illumination.

Answer 1

Where under the 82.1% of the AM1.5G illumination the short circuit current density is Jsc is 23 mA/cm

For the cell under full(100%) AM1.5G illumination the short circuit current density becomes = (23*100)/82.1 = 28.01 mA/cm
