Differences between light emitting diode and photodiode
1. It is forward biased
1. It is reverse biased
2. Recombination of electrons and holes takes place at the junction and light is emitted (hv). Light energy (hv) falling on the p-n junction creates electron-hole pair which increases photocurrent.
