IanP said:A photodiode has two equivalent resistances: series and shunt ..
The series resistance is several ohms and the shunt resistance is 10MΩ - 100 000MΩ ..
The series resistance can be obtained from a particular diode's data sheet ..

IanP said: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 ..
