Modulating the structure and property of hole-transporting organic semiconductors is of paramount importance for high-efficiency and stable perovskite solar cells (PSCs). This work reports a low-cost peri-xanthenoxanthene based small-mol. P1, which is prepared at a total yield of 82% using a 3-step synthetic route from the low-cost starting material 2-naphthol. P1 mols. stack in 1-dimensional columnar arrangement characteristic of strong intermol. π-π interactions, contributing to the formation of a solution-processed, semicrystalline thin-film exhibiting one order of magnitude higher hole mobility than the amorphous one based on the state-of-the art hole-transporter, 2,2-7,7-tetrakis(N,N’-di-paramethoxy-phenylamine 9,9′-spirobifluorene) (spiro-OMeTAD). PSCs employing P1 as the hole-transporting layer attain a high efficiency of 19.8% at the standard AM 1.5 G conditions, and good long-term stability under continuous full sunlight exposure at 40°C. The experimental part of the paper was very detailed, including the reaction process of Bis(4-methoxyphenyl)amine(cas: 101-70-2Application In Synthesis of Bis(4-methoxyphenyl)amine)
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.Application In Synthesis of Bis(4-methoxyphenyl)amine
