7-bromo-1,1,1-trifluoro-2-heptanone (BTH) can be used as an interfacial modifier.1
| [Description]
P-type dopant molecules 7-bromo-1,1,1-trifluoro-2-heptanone (BTH) was innovatively added in perovskite precursor to decrease the internal reorganization energy including electron reorganization energy (λe) and hole reorganization energy (λh), thus improving Marcus charge transfer rate (KCT) and charge mobility (μ). 1
