Abstract

The invention discloses a conjugated polymer bulk heterojunction film with optical anisotropy and a preparation method and application thereof. The preparation method comprises the following steps ofpreparing a mixed solution containing an electron donor and an electron acceptor, then guiding flow on an orthogonal solvent liquid level by using a groove mold printing head, and injecting the mixedsolution to form a regular strip-shaped film. In the solvent volatilization process, two macromolecules form an ordered arrangement structure film through self-assembly, and the film floats on the surface of the orthogonal solvent liquid. The two macromolecules in the film are arranged in order and have optical anisotropy, and the film has the excellent photovoltaic characteristics due to the charge transfer effect between the two macromolecules. A solar cell device and an optical detector prepared by using the film can realize the polarized light angle sensitive response and the polarized light sensitive detection, and have good application prospects in astronomy, medical science, industry, military affairs, civil use and other fields.

Description

technical field [0001] The invention belongs to the technical field of polarized light detectors, and in particular relates to a conjugated polymer heterojunction thin film with optical anisotropy and its preparation method and application. Background technique [0002] The polarization state is an important feature of electromagnetic waves. According to the different polarization states, electromagnetic waves are divided into linearly polarized light, circularly polarized light, and elliptically polarized light. After the light beam interacts with matter, it is reflected, transmitted, and scattered, and its polarization state will change, carrying multiple information such as geometric shape, material structure, and relative distance. Therefore, the detection and utilization of polarized light is an extremely important application. Research has incomparable application advantages in many fields such as astronomy, medicine, industry, military and civilian use. Different fro...
