Difference between LED and Photodiode
Photodiode converts light or photon into electrical current due to the photoelectric effect. When a photon strikes the exposed junction of the photodiode, it generates electron-hole pairs. Due to the built-in electric field between the P-type and N-type semiconductor, the electron and hole flows in the opposite direction and eventually into the external circuit.
