Problems solved by technology

[0004] Although the above methods of enhancing the photoelectric conversion efficiency of OPV have certain effects in some aspects, the conventional methods of enhancing light concentration or reflection and refraction of sunlight through optical design to improve device performance have certain limitations.
1. Need to have a certain background in physical optics, and be able to perform more accurate optical simulations and calculations; 2. The structure of the light-condensing plate and reflective / refractive plate needs to be precisely controlled; 3. The manufacturing process is relatively complicated, resulting in higher costs
This affects the promotion of OPV in real-world applications

Abstract

The invention discloses an organic solar cell with adjustable incident light intensity and a preparation method thereof. The device comprises a photoluminescent layer, a transparent substrate, a transparent electrode, a cavity injection layer, a donor layer, a receptor layer, an electronic transport layer and an electrode cathode. The donor layer is a traditional organic solar cell material with strong absorption in a narrowband system, and the receptor layer is a non-fullerene or traditional electronic transport material. The device carefully chooses the photoluminescent layer and deposits the photoluminescent layer on one side of the transparent substrate. By exciting the photoluminescent layer through sunshine, the photoluminescent layer emits blue light, green light or yellow light, and the additional photons of the organic solar cell enhance the incident light intensity. By calcining the photoluminescent layer, the photoluminescence intensity at different degrees can be obtained, and the solar spectrum can be adjusted. The device increases the incident light intensity in a simple way without additional focusing plates, reflection / refraction plates and micro-nanostructures, and the incident light intensity is adjustable. The device is superthin, the preparation technology is simple, and the requirement on equipment is low.

Description

Technical field [0001] The invention relates to an organic optoelectronic device and a preparation method thereof, in particular to an organic solar cell (OPV) and a preparation method thereof, and is applied to the technical field of green solar energy sources. Background technique [0002] Since 1954, Bell Laboratories in the United States successfully developed silicon solar cells, pioneering the research of photoelectric conversion, and then the research on solar cells has developed rapidly. Due to the high production cost of inorganic solar cells, complex production processes, and severe photo-corrosion of narrow band gap semiconductors, the popularization and application of solar power generation technologies are largely restricted. With the rapid development of the field of organic semiconductors, the popularization and application of low-cost solar power generation technology has become possible. Compared with traditional silicon-based and other inorganic metal compound ...
