Photodiodes are semiconductor light sensors that generate a current or voltage when the P-N junction in the semi- conductor is illuminated by light. The term photodiode can be broadly defined to include even solar batteries, but it usually refers to sensors used to detect the intensity of light. Photodiodes can be classified by function and con- All of these types provide the following features and are widely used for the detection of the presence, intensity Excellent linearity with respect to incident light Wide spectral response range Mechanically rugged Long life Si photodiodes manufactured...
