Abstract
The invention relates to an organic light emitting diode (OLED), also referred to as a light emitting diode, which comprises at least one substrate, one anode, one hole transport layer, one emitter layer, one cathode and one encapsulation. It is proposed that an energy carrier, which supplies the voltage that causes the OLED to emit light, be integrated into the OLED. The energy carrier can be a battery (energy storage device) or an energy converter (photovoltaic element).
