| titleOfInvention | A kind of asymmetric hole transport material and its preparation method and application |
| abstract | The invention discloses an asymmetric hole transport material, a preparation method and application thereof. The material uses tetrathienopyrrole as the molecular core, and methoxytriphenylamine, indeno[1,2- b ]carbohydrate on both sides respectively. azole is a peripheral modification group, the hole transport material of the present invention can effectively synergize the advantages of the peripheral modification groups on both sides, and utilize the rigid and planar spatial configuration of indeno[1,2- b ]carbazole to enhance hole transport The interaction between the molecules of the material improves the electrical conductivity and hole mobility, and the three-dimensional twisted space structure of methoxytriphenylamine is used to suppress the interfacial carrier recombination; in addition, the reduction of molecular symmetry can also effectively improve the dissolution and film formation of the material performance, which is conducive to obtaining high-quality amorphous thin films. The asymmetric hole transport material of the present invention is applied to the perovskite solar cell, the short-circuit photocurrent density of the battery device reaches 22.98 mA cm -2 , the open-circuit voltage is 1.099 V, the filling factor is 0.7923, the photoelectric conversion efficiency is as high as 20.01%, and the display is broad. prospects for commercial applications. |
