Understanding the Voltage – Current (I-V) Curve of a Solar Cell

The operating point (I, V) corresponds to a point on the power-voltage (P-V) curve, For generating the highest power output at a given irradiance and temperature, the operating point should

Characteristic Resistance

The characteristic resistance of a solar cell is the cell''s output resistance at its maximum power point. If the resistance of the load is equal to the characteristic resistance of the solar cell, then the maximum power is transferred to the load,

Shunt Resistance

The effect of shunt resistance on fill factor in a solar cell. The area of the solar cell is 1 cm 2, the cell series resistance is zero, temperature is 300 K, and I 0 is 1 x 10-12 A/cm 2.Click on the graph for numerical data. An estimate for the value

Shunt Resistance

Low shunt resistance causes power losses in solar cells by providing an alternate current path for the light-generated current. Such a diversion reduces the amount of current flowing through the solar cell junction and reduces the voltage from
