Abstract

An electronic device performing as a light emitting diode and a solar cell, and which comprises: a solar cell unit including a first electrode layer, an energy-level compensation layer formed on the first electrode layer, a photoelectric-conversion layer formed on the energy level compensation layer, and a shared electrode layer formed on the photoelectric-conversion layer; and a light emitting diode unit including the shared electrode layer, and a light emitting layer formed on the shared electrode layer and a second electrode layer formed on the light emitting layer, wherein a LUMO energy-level of the energy-level compensation layer is smaller than a work function of the first electrode layer and is larger than a LUMO energy level of the photoelectric-conversion layer, thereby increasing the generating efficiency of the solar cell unit or the luminous efficiency of the light emitting diode unit due to high electron mobility among the respective layers.
