Two novel phenothiazine 5,5-dioxide (PDO) core building block-based hole transport materials (HTMs), termed PDO1 and PDO2, were designed and synthesized. The introduction of a sulfuryl group in a core unit can deeply influence the energy levels and charge carrier mobilities of relative HTMs. The combined suitable energy level alignment, higher hole mobility and conductivity, as well as highly efficient hole transfer of PDO2 enable the perovskite solar cell (PSC) to achieve an impressive power conversion efficiency (PCE) of 20.2% and good stability when aged under ambient conditions. These results demonstrate the potential versatility of the PDO building block for further development of cost-effective and highly efficient HTMs for PSCs. In the part of experimental materials, we found many familiar compounds, such as Bis(4-methoxyphenyl)amine(cas: 101-70-2Application of 101-70-2)
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 of 101-70-2
