Their HOMO levels match the valence band energy of CH₃NH₃PbI₃. The introduction of ferrocenyl was aimed to obtain hole transporting materials with high mobility for perovskite solar cells. JW7 shows higher hole mobility (4.2 × 10^-4 cm² V^-1 s^-1) than JW6 (1.3 × 10^-4 cm² V^-1 s^-1) and JW8 (1.5 × 10^-4 cm² V^-1 s^-1). Their film-forming properties are affected by their molecule structures. The methoxyl and <i>N</i>,<i>N</i>-dimethyl terminal substituents of JW7 and JW8 are beneficial for having better solubility than RSC advancesNew ferrocenyl-containing organic hole-transporting materials for perovskite solar cells in regular (n-i-p) and inverted (p-i-n) architectures.PMC9059360215061642167114821576215Duan LZong XXue SWu QChen YSun ZJia JfalseNew ferrocenyl-containing organic hole-transporting materials for perovskite solar cells in regular (n-i-p) and inverted (p-i-n) architectures.Three triphenylamine derivatives containing ferrocenyl groups (JW6, JW7 and JW8) were synthesized by facile syntheses.
