Problems solved by technology

[0005] In addition to German automobile companies investing billions of dollars in research on smart car glass and other related directions, most of the research at home and abroad is focused on the research of single OPV or OLED. These researches make the light conversion efficiency of OPV reach more than 10%, and the life of OLED reaches 50,000 hours Above, the highest brightness can reach more than 10 million cd / m2, but the idea and products of using all organic light source devices have not yet been produced. The existing green light sources are usually connected by different devices through wires, which is not convenient to use. relatively low level of integration

Embodiment 1

[0037] In this example, see Figure 1 ~ Figure 3 , an OPV-driven OLED light source, including a rigid transparent substrate a, OPV component b, common electrode layer c, OLED component d, OPV controller and memory e, the transparent substrate a adopts a rigid ITO substrate, and the OPV device b collects the sun The light energy is converted into electrical energy through the controller, powers the OLED light-emitting component d through the common electrode layer c, and stores it in the OPV controller and memory e. The OPV controller and memory e are made of organic materials. The OPV controller and memory e are effectively connected with OPV component b and OLED component d. The OPV controller, memory e, OPV component b and OLED component d are all transparent devices, which form a plate-shaped integrated system through stacked assembly and embedded assembly. The OPV controller and memory e automatically supply power to the OLED device d when the light is insufficient, so as ...

Embodiment 2

[0053] This embodiment is basically the same as Embodiment 1, especially in that:

[0054] In this embodiment, the transparent electrode substrate is prepared by using the transparent electrode to be deposited on a flexible plastic substrate with relatively high light transmittance. In this embodiment, the organic solar cell obtains electric energy by converting light energy and stores it, so that it can be released again to drive the OLED when the energy needs to be utilized. Since all components can be made into organic products, each component of the present invention can be made flexible and transparent.

Abstract

The invention discloses an OPV-driven OLED light source and a preparation method thereof. The OPV collects sunlight and stores it in an energy storage and a controller. The energy storage and the controller are made of organic materials. The energy storage and the controller, the OPV and the OLED After assembly, OPV, energy storage and OLED are all transparent or translucent devices. A plate-shaped integrated system is formed through stacked assembly and embedded assembly. The energy storage and the controller control the energy storage to automatically supply power to the OLED, thereby realizing the OPV-driven OLED. The light source emits light. The active layer of OPV has a double-layer structure. The active layer is made of materials with narrow bandgap width. The dual emission layer of OLED is formed by doping the guest material in the host molecular material at a low concentration. The integrated system of the present invention uses all organic materials to make a translucent integrated system, which has low preparation cost, is environmentally friendly and simple in process, provides a new idea for the future lighting industry, and has a wide range of uses for the finished product.

Description

technical field [0001] The invention relates to an artificial light source and a preparation method thereof, in particular to a light source which is powered by solar power to drive semiconductor devices to emit light and a preparation method thereof, which is applied in the technical field of green lighting. Background technique [0002] Both organic solar cells (OPV) and organic light-emitting diodes (OLED) originated in the field of inorganic semiconductors. Since American chemist A. G. MacDiarmid, physicist A. J. Heeger and Japanese chemist H. Shirakawa jointly discovered that iodine-doped polyacetylene (PA) has metallic properties in 1977, the organic semiconductor industry has been greatly developed. Because of its environmental friendliness, easy access to raw materials, and many advantages such as free synthesis of structures required by humans, countries have paid great attention to the organic semiconductor industry. [0003] OPV has experienced the development pr...
