Abstract

The invention discloses an n-type organic small molecule semiconductor based on indenothiophene as a core as well as a preparation method and an application of the n-type organic small molecule semiconductor, and particularly provides the n-type organic small molecule semiconductor based on indenothiophene as the core, thiophene as a bridge and 1,3-indanedione, malononitrile or 2-(5,6-difluoro-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile as an end group, the preparation method of the n-type organic small molecule semiconductor and the application of molecules as a receptor material in organic non-fullerene solar cells. The n-type organic small molecule semiconductor based on indenothiophene as the core has the advantages of capacity of processing in a solution form, wide absorptionspectrum, high absorption coefficient, excellent thermal stability and appropriate energy level, and is an ideal non-fullerene receptor material for organic solar cells.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to an n-type organic small molecule semiconductor based on indenothiophene as the core and its preparation method and application. Background technique [0002] Solar energy is an inexhaustible clean and green energy. In recent years, with the attention of countries all over the world on energy issues, solar cells have become a research hotspot in this field. Compared with traditional inorganic semiconductor solar cells, organic solar cells have outstanding advantages such as low cost, less material, light weight, simple manufacturing process, and can be prepared into flexible devices, etc., and have broad development and application prospects. [0003] A typical organic solar cell adopts a bulk heterojunction structure, and its active layer consists of a p-type semiconducting polymer as a donor material and an n-type semiconductor as an acceptor material. [1-3] . Fullerene and i...
