Electrical Engineering | A photoelectric receptor in which absorption of radiation in the neighbourhood of a p-n junction between two semiconductors, or of a contact between a semiconductor and a metal, produces a change of resistance depending on the current direction.

(From Wikipedia, the free Encyclopedia)
Photodiodes can be used in either zero bias or reverse bias. In zero bias, light falling on the diode causes a voltage to develop across the device, leading to a current in the forward bias direction. This is called the photovoltaic effect, and is the basis for solar cells - in fact a solar cell is just a large number of big, cheap photodiodes.
Diodes usually have extremely high resistance when reverse biased. This resistance is reduced when light of an appropriate frequency shines on the junction. Hence, a reverse biased diode can be used as a detector by monitoring the current running through it. Circuits based on this effect are more sensitive to light than ones based on the photovoltaic effect.
A phototransistor is in essence nothing more than a normal bipolar transistor that is encased in a transparent case so that light can reach the Base-Collector diode. The phototransistor works like a photodiode, but with a much higher sensitivity for light, because the electrons that tunnel through the Base-Collector diode are amplified by the transistor function.
