Improving the performance of arylamine-based hole transporting materials in perovskite solar cells: Extending π-conjugation length or increasing the number of side groups?

         

摘要

cqvip:In this work, we prepared three simple arylamine-based hole transporting materials from commercially available starting materials. The effect of extending 7 r-conjugation length or increasing the number of side groups compared with reference compound on the photophysical, electrochemical, hole mobility properties and performance in perovskite solar cells were further studied. It is noted that these two kinds of molecular modifications can significantly lower the HOMO level and improve the hole mobility, thus improving the hole injection from valence band of perovskite. On the other hand, the compound with more side groups showed higher hole injection efficiency due to lower HOMO level and higher hole mobility compared with the compound with extending π-conjugation length. The perovskite solar cells with the modified molecules as hole transporting materials showed a higher efficiency of 15.40% and 16.95%,respectively, which is better than that of the reference compound(13.18%). Moreover, the compound with increasing number of side groups based devices showed comparable photovoltaic performance with that of conventional spiro-OMeTAD(16.87%).
