Problems solved by technology

However, because the degree of polymerization of the polymer itself is difficult to control, not only is it not conducive to the analysis of its structure, but also the different degree of polymerization will also affect the performance of the device, resulting in differences in batches of polymer devices

Abstract

The invention provides an organic solar cell donor material containing benzoselenadiazole and diindolocarbazole, and an application thereof. The organic solar cell donor material TAT-Th-BSe has a D-pi-A-pi-D structure formed by connecting 2,1,3-benzoseladiazole used as an electron acceptor unit, 5,10,15-tributyl-diindolo[3,2-A:3',2'-C]carbazole as an electron donor unit and 3-dodecylthiophene usedas a pi bridge. The donor material TAT-Th-BSe and the acceptor material PC71BM are used as the active layer of an organic solar cell device to obtain a bulk heterojunction organic solar cell device,and the structure of the battery device is ITO / ZnO / active layer / MoO3 / Al.

Description

Technical field [0001] The invention relates to the technical field of organic solar cell materials, in particular to an organic solar cell donor material containing benzoselenodiazole and diindolocarbazole and its application. Background technique [0002] In 1959, Kallman et al. (Journal of Chemical Physics, 1959, 30, 585) prepared organic solar cell devices for the first time by adding two electrodes to both ends of organic material single crystal anthracene. This was the first time that organic materials were used as solar energy absorption and conversion materials. The low conversion efficiency has not attracted people's attention for a long time. In 1986, Tang et al. (Applied Physics Letters, 1986, 48, 183) reported for the first time an organic solar cell device with a double-layer D-A structure, and the device conversion efficiency was close to 1%. In 1995, Heeger et al. (Science, 1995, 270, 1789) made a breakthrough in the field of organic solar cell devices, and propos...
