Abstract
An organic photodetector includes an anode and a cathode facing each other and an active layer between the anode and the cathode and including a p-type semiconductor and an n-type semiconductor, wherein an energy barrier between the anode or the cathode and the active layer is greater than or equal to about 1.3 eV, a difference between a HOMO energy level of the p-type semiconductor and a LUMO energy level of the n-type semiconductor is greater than or equal to about 0.8 eV.
