Hi,
I would like to measure the series resistance of a photodiode. Could you please help me on this matter. I bias the photodiode in the forward direction (0.3-0.5 V) and try to analyse the data but I am skeptical about this method as we do not know whether such high currents flowing may damage the optical properties of the photodiode or not.
Thanks in advance!

The series resitance of a photodiode in not as important as the shunt resistance ..
It is common industrial practice to put a 10mV reverse bias on the photodiode and measure current ..
The ratio between the bias voltage and current determine the shunt resistance value ..
