Hi, I am trying to measure IV characteristics of a solar cell, the circuit is very simple, there is the solar cell, potentiometer, and a shunt resistor. The idea is to change value on potentiometer from zero to 1M Ohm and measure voltage on the cell and current it gives (voltage on the shunt resist…

Measuring very low current (using op amps)

What resistance shunt are you using?

Is it possible to increase the resistance of the shunt?
