In a general way, the reverse current of crystalline silicon solar cells originates in cell defects and impurity centers in the materials and can be represented by a shunt resistance. We chose 71 cells (125 mm × 125 mm) whose reverse current is smaller than 1.0 A at V = −12 V and the shunt resistance is larger than 20 Ω.
Internal resistance
In a 0.6V/150mV silicon solar cell, the internal resistance is up to 4 ohms in bright lighting. This is why the voltage drops significantly when a low-resistance load is connected.
