Explain the Photosensitive Detectors?

A wide range of detectors varying in senstivity and cost are available. They contain a light sensitive surface that releases electrons in number proportional to the intensity of light on it, converting light energy into electrical energy. The current thus generated is a direct function of the light intensity. Different detectors used are:

a) Barrier layer cells

b) Photoemissive tubes

c) Photomultiplier tubes

d) Photoconductive cells
