Photodiode | Construction, Working, and Applications | Explained in 6 Mins

The video offers a comprehensive explanation of the photodiode, an electronic device that converts light energy into electrical energy. It begins by defining the photodiode as a two-terminal device typically operated in a reverse-biased mode where current flows upon exposure to light. The video details the construction of the photodiode using P-type and N-type semiconductor layers, emphasizing the use of an anti-reflection material on the active surface to maximize light conversion. Furthermore, the video thoroughly explains the working principle, including how photons striking the junction dislodge valence electrons to generate current, and discusses the two modes of operation: photo-conductive and photo-voltaic. Watch the video till the end for a complete explanation.
