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 of the invention includes a photoluminescence layer, a transparent substrate, a transparent electrode, a hole injection layer, a donor layer, an acceptor layer, an electron transport layer and electrode cathode. The donor layer is traditional organic solar cell material with narrow band and strong absorption, and the acceptor layer is non-fullerene or traditional electron transport material. The device of the invention selects the photoluminescent layer and deposits it on one side of the transparent substrate. The photoluminescent layer is excited by sunlight to emit blue light, green light or yellow light, and the additional photons of the organic solar cell will enhance the incident light intensity. And by calcining the photoluminescence layer, different intensities of photoluminescence intensity can be obtained, thereby adjusting the sunlight spectrum. The device uses a simple method to increase the incident light intensity without other additional light-condensing plates, reflection / refraction plates and micro-nano structures, and is adjustable. The device is ultra-thin, the preparation process is simple, and the equipment requirements are 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, which are applied in the technical field of green solar energy. Background technique [0002] Since 1954, Bell Laboratories in the United States successfully developed silicon solar cells, pioneering photoelectric conversion research, and then research on solar cells developed rapidly. Due to the disadvantages of inorganic solar cells such as high production cost, complex production process, and severe photocorrosion of narrow-bandgap semiconductors, the popularization and application of solar power generation technology is largely restricted. With the rapid development of the field of organic semiconductors, the popularization and application of low-cost solar power generation technology becomes possible. Compared with traditional silicon-based and other inorganic metal compound sol...
