the function of this diode is opposite of LED when light is incident on it,it conducts .it is manufactured with cadmium selenide ,cadmium sulphide in addition to germainum and silicon the current through photodiode depends on the light intensity .photodiode is normally operated in reverse bias when it is exposed to light due of energy of light ,electrons-hole pairs are generated therefore current flows through it.photodiode is a transducer converts light energy into electrical energy.
