A photodiode is a type of photodetector capable of converting light into either current or voltage, depending upon the mode of operation. Its characteristics is same as that of an ordinary diode, except that it depends on light.

The 2N5777 is a Darlington silicon NPN photo detector, or, if you prefer a photoDarlington. A link is provided to a bit of data on this device.

Absolutely not. An ideal diode's characteristic would be perfect conduction in the forward direction and perfect insulation (no conduction) in the reverse direction. Silicon diodes come respectably close.
in colleges for GEDS assignment which is well hard mate!

A Photo-diode is used to receive light. whereas the L.E.D. is a Light Emitting Diode.

It conducts in only one direction.
A diode characteristic curve is a curve that describes the characteristic of diode and it is normally based on experiment data. The curve itself has two distinctly separate parts.One part lies in the first quadrant and it stands for the forward-biased situtation.It reflets the barrier voltage(meaning the smallest amount of voltage that can turn on the diode).For Germannium diode,the barrier voltage is 0.3V while silicon diode is 0.7V,but the real value differs according to the temperature and current flows through the diode.The other part lies in the third quadrant which indicates the reverse-biased situation,from which you can find out the leakage current(the current flow through before Breakdown Point). Typcially, a diode characteristic curve varies from diode to diode.But theoretically speaking,we regard them as the same.
