Greetings.

For measuring DSSC I-V curve, the circuit I use consists of a solar cell, a single multimeter to measure voltage, and a potentiometer.

then I want to calculate current, I = V/R:

First I connect the pot to the DMM and I record a value of resistance (R!), after that

I connect the solar cell to the same circuit,in parallel, and measure the  voltage (V1) ,

then I calculate current (I1)

I1 = V1/R1

Again I disconnect the cell, and repeat the above procedure getting different values

of current.

So, is the above method correct?

I appreciate your response and thank you.
