[0002] An organic optoelectronic diode is a device capable of converting electrical energy and light energy.

[0003] Organic optoelectronic devices can be broadly divided into two types based on their operating principles. One is a photovoltaic device that generates electrical energy as excitons formed by light energy are separated into electrons and holes, and the electrons and holes are transferred to different electrodes, and the other is a light-emitting device that generates light energy from electrical energy by supplying voltage or current to electrodes.
