Organic-inorganic hybrid light emitting device, method for manufacturing the same, and organic-inorganic hybrid solar cell

摘要

The present invention provides an organic-inorganic composite light-emitting device including a luminescent layer emitting high-brightness light using low voltage, wherein the luminescent layer has a sandwich structure in which organic luminescent layers are formed on both sides of an inorganic thin film layer.;The organic-inorganic composite light-emitting device configured as above is advantageous in that an inorganic thin film layer is inserted and formed between organic luminescent layers, and thus the injection of electrons that occurs when low voltage is applied stabilizes the structure of the luminescent layer, thereby emitting brighter light. Further, the organic-inorganic composite light-emitting device is effective in greatly improving the power efficiency of an organic light-emitting device by greatly increasing the luminance efficiency thereof. Moreover, the organic-inorganic composite light-emitting device can exhibit improved luminance efficiency at low cost because it can be manufactured by directly using a conventional organic light-emitting device structure and a conventional process of manufacturing an organic light-emitting device.
