Two asym. three-dimensional (3D) hole-transporting materials (HTMs) containing a triphenylethylene core and peripheral diphenylamine/triphenylamine moieties are first synthesized and successfully used in perovskite solar cells (PSCs). Both HTMs are obtained from facile preparation procedures and simple purification techniques. The X-ray diffraction, aggregation-induced emission properties, absorption and emission spectra, electrochem. properties, thermal stability, d. functional theory calculations, hole mobility, scanning electronic microscopy, at. force microscopy, steady-state and time-resolved photoluminescence, water contact angles, and photovoltaic parameters of the PSCs are compared. The highest power conversion efficiency increases from 12.57% (CJ-02) to 18.56% (CJ-01), rivaling that obtained from the state-of-the-art 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (spiro-OMeTAD) (18.69%). Further, the lab synthetic cost of CJ-01 is only about 15.5% of the price of com. spiro-OMeTAD, and the concentration of CJ-01 solution for device fabrication is less than half of the concentration of spiro-OMeTAD solution (30.0 vs 72.3 mg mL-1). These results demonstrate that the propeller-shaped compounds with a highly twisted conformation are readily available and promising alternative HTMs for PSCs. Moreover, an applicable strategy to design new HTMs with 3D structure for achieving highly efficient PSCs is proposed. In addition to this study using Bis(4-methoxyphenyl)amine, there are many other studies that have used Bis(4-methoxyphenyl)amine(cas: 101-70-2HPLC of Formula: 101-70-2) was used in this study.
Bis(4-methoxyphenyl)amine(cas: 101-70-2) is a diphenylamine derivative used as a chemical additive for cured rubber.Bis(4-methoxyphenyl)amine is highly toxic and may potentially induce chromosome abberation.HPLC of Formula: 101-70-2
