Since the report by Lee et al. in 2012, spiro-MeOTAD has been widely used as a hole transport layer in perovskite solar cells, although alternative materials have also been actively investigated.
Poly(3-hexylthiophene) (P3HT), a thiophene-based polymer, exhibits relatively high charge carrier mobility and has been reported as a hole transport material for perovskite solar cells. However, the charge transport properties of P3HT strongly depend on its molecular orientation, and therefore devices employing Lewis acid doping, similar to spiro-MeOTAD, have been developed.
In this study, the film properties of a hole transport layer doped with the Lewis acid tris(pentafluorophenyl)borane (TPFB) were evaluated in comparison with those of spiro-MeOTAD.
