| titleOfInvention | A kind of hole transport material based on indeno[1,2-b]carbazole and its preparation method and application |
| abstract | The invention discloses a hole transport material based on indeno[1,2- b ]carbazole, a preparation method and application thereof. The material uses electron-rich indeno[1,2- b ]carbazole as a peripheral modification group, tetrathienopyrrole is a rigid planar molecule with the molecular core, and its general structural formula is as follows: , in the formula, R 1 is one of C1~C12 straight chain, branched chain alkyl or alkoxy chain, R 2 and R 3 are C1~C12 straight chain or branched chain alkyl. The hole transport material of the invention has a simple synthesis route, is easy to separate and purify, and exhibits excellent dissolution film-forming properties and high hole extraction efficiency. The hole transport material based on indeno[1,2- b ]carbazole of the present invention is applied to perovskite solar cells, the short-circuit photocurrent density of the battery device is 23.87 mA cm -2 , the open-circuit voltage is 1.112 V, and the filling factor is 23.87 mA cm-2. It is 0.7923, and the photoelectric conversion efficiency is as high as 21.03%, showing broad commercial application prospects. |
