Question

How to calculate series and shunt resistance of solar cells in origin?

Answer 1

Answer:

Step 1

Write down the Ohm's law expression of "V = I * R" where "V" is the voltage drop across shunt resistor, "I" is the current flowing through shunt and "R" is the shunt resistance.

Step 2

Substitute value of voltage "V" and current "I" in the Ohm's law expression. For example, if voltage across shunt is 10 volts and current flowing through it is 1 ampere, then the expression is 10 = 100 * R.

Divide the expression throughout by 100 to calculate the "R" value. Using a calculator, find the value of "R." From the example, the value of "R" will be 0.1 ohm, which is the value of shunt resistor.

Answer 2

Explanation:

this is about the standard equivalent circuit of a solar cell which serves to describe the actual device with all its real-world properties (e.g., internal leakgae currents and/or internal voltage losses) by idealized components (as, e.g., perfect photocurrent source, ideal p-n junction diode). Only in combination with additional components (e.g., series and shunt resistance), put together with the ideal components in a straightforward way, this equivalent circuit is supposed to mimic the behavior of the actual device. Thus, series and shunt resistance are just means to account for the internal leakgae currents and/or internal voltage losses of real-world devices.
