HOLE TRANSPORTING LAYER FOR LIGHT EMITTING DEVICES AND SOLAR CELLS AND METHOD FOR MANUFACTURING THE SAME

摘要

Provided are a hole transporting layer for a light emitting device and a solar cell and a method for manufacturing the same. The hole transporting layer for the light emitting device and the solar cell is formed of nickel oxide (NiO) formed by oxidizing a side of a conductive thin film formed of a flexible metal. A method of manufacturing a hole transporting layer for a light emitting device and a solar cell includes preparing a conductive thin film formed of a flexible metal and thermally treating the conductive thin film in oxygen atmosphere to form an oxide layer, thereby forming a hole transporting layer. Therefore, productivity can be improved, and the hole transporting layer adapted for the light emitting device and the solar cell can be manufactured by selectively changing formation conditions when the oxide layer is formed.
