What is the difference between photodiode & photocell...

Answer / joe gh.

A photocell, also refered as a photoresistor has a resitance that depends on the intensity of light that is hitting it.

This is not the case for photodiodes, which light to current (or tension) conversion depends not on the intensity of light but on the operating mode : (photovoltaic zero biased for example)
