For a 0.017 m2 PV cell, the reverse saturation current is I0 = 4 × 10−11 A and at an insolation of 1-sun (1 sun = 1000 W/m2) the short-circuit current is ISC = 6.4 A. Assume the cell temperature is 25°C, parallel resistance Rp= 5 Ω and series resistance Rs= 0.05 Ω, draw the I-V plots based on the four equivalent electrical circuits we discussed:
1) the simplest circuit without Rp and Rs
2) the circuit with Rp only
3) the circuit with Rs only
4) the circuit with both Rp and Rs
