General Description

N-Octyl-2,7-dibromocarbazole is a chemical compound that is a variant of carbazole, distinguished by its octyl chain and two bromine atoms. Current data regarding its specific applications or hazards is limited, but it can be inferred from its structure that it has potential use in organic materials such as electronics due to the semiconducting properties of carbazole compounds. Carbazoles generally are heterocyclic organic compounds containing a three-ring system, known for their fluorescent properties and are key components in a variety of chemical applications. However, specific information about the properties, uses, and safety of N-Octyl-2,7-dibromocarbazole is sparse and is a subject for future research.

Two Anthracene-Based Copolymers as the Hole-Transporting Materials for High-Performance Inverted (p-i-n) Perovskite Solar Cells

Two anthracene-based copolymers, the thiophene-bridged carbazole-anthracene copolymer (abbreviated as PCBZANT) and the thiophene-bridged triphenylamine-anthracene copolymer (abbreviated as PTPAANT), have been developed as the hole-transporting materials (HTMs) for the inverted perovskite solar cells. They were thermally stable with decomposition temperatures of 435 and 420 °C. The High Occupied Molecular Orbitals (HOMO) of -5.15 and -5.24 eV of two copolymers facilitated the hole carriers transfer from the perovskite layer (CH3NH3PbI3, HOMO: -5.4 eV) in contrast to poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS, HOMO: -4.9 eV). The solar cell with PCBZANT (abbreviated as the PCBZANT device) showed the highest power conversion efficiency (PCE) of 15.50%, while the cell with PTPAANT (abbreviated as the PTPAANT device) showed the highest PCE of 14.52%, with increases of 36.2% and 27.6%, respectively, relative to the PEDOT:PSS device. The thorough analysis disclosed that the high performance was mainly ascribed to the enhanced open-circuit voltage (VOC) and short-circuit current density (JSC), being contributed from the efficient hole-carrier extraction, the high hole mobility of two copolymers, and the high-quality perovskite film with large crystal size and less defect. With strong absorption in the range of 350-500 nm, the polymers decreased the destruction of UV-radiation on the perovskite layer as UV-filters and improved the stability of the inverted cells.
