I tried today to calculate the power that the solar cell produced, connecting it to an ammeter(digital) and a voltmeter(digital) in series, my initial idea was to use the P=IV formula. However as i carried out the experiment the ammeter gave a showed 0.00 whilst the voltmeter showed 0.56 volts.Then i tired to place a resistor in series to increase the resistance of the circuit to see wether the ammeter showed any reading however there where still 0.00 .Is there any other way to calculate the power of the solar cell without having to find the current?
If so could could someone explain how thanks in advance.
