Abstract

The invention discloses an organic photovoltaic and electroluminescent combined display device and a production method thereof. The display device comprises an organic photovoltaic component and an organic electroluminescent component which are arranged on two sides of the same glass substrate. A metallic cathode of the organic photovoltaic component is connected with an ITO (indium tin oxide) conductive layer of the organic electroluminescent component, and an ITO conductive layer of an anode of the organic photovoltaic component is connected with an ITO conductive layer of the organic electroluminescent component. The organic photovoltaic component is used as a direct-current power source supplying direct-current voltage driving for luminescent devices, the open circuit voltage generated from the organic photovoltaic component is lower, and the driving voltage for the luminescent device is met by a series battery structure formed of multiple blocks. An electronic injection layer of the organic electroluminescent component is a polycrystal LaB6 which is transparent and has lower power function, both top emission and bottom emission of the luminescent devices can be realized, and light emitted from the bottoms of the luminescent devices permeates an Ag electrode layer on the other surface of the glass to be further reflected so that the brightness of light emitted from the tops of the luminescent devices can be enhanced.

Description

technical field [0001] The invention relates to a display device combining organic photovoltaic and organic electroluminescence, in particular to a structure and a preparation method of a display device combining organic photovoltaic electroluminescence. Background technique [0002] Organic photovoltaic devices refer to polymer solar cells (Polymer Solar Cells, PSCs). When sunlight irradiates polymer semiconductors, photons with a wavelength not greater than the band gap of the material are used in the sunlight, and the polymer material absorbs the photons to produce bound Electron-hole pairs (excitons) that come together dissociate into electrons and holes (carriers) when they diffuse to the metal cathode and polymer interface. Under the action of the built-in electric field of the semiconductor, the carriers move to the opposite electrode and are collected on the electrode, thereby generating photocurrent in the external circuit. The preparation method is simple, the cos...
