description A tandem Organic Light Emitting Diode (OLED) apparatus and method of fabricating the same, where the tandem OLED apparatus includes a buffer assisted charge generation layer having a junction of a p-type doped semiconductor layer and an n-type doped semiconductor layer, where a hole buffer layer and an electron buffer layer pair surrounding the junction of the p-type and n-type doped semiconductor layers. The OLED apparatus further includes a first OLED emissive layer and a second OLED emissive layer pair surrounding the buffer assisted charge generation layer, and a cathode and anode layer pair further surrounding the first and second OLED emissive layer pair.
