Working principle of the photodiode and photoresistor

[QUOTE="akzo, post: 5462736, member: 581125"] Hello everyone. I feel myself a little bit confused because I can't understand the difference between the working principle of the photodiode and the photoresistor. The photoresistor changes its resistance under the influence of light while photodiode changes the current across iself. Is this right? I also know that photoresistor use the principle called photoconductivity, but what principle is used by photodiode then? I guess there should be some difference, because why we are talking about resistance in one case and about current in another? Thanks in advance. [/QUOTE]
