With enhanced crystallinity and hole extraction ability, using PTAA/M2 instead of pure PTAA as HTL, the power-conversion efficiency of inverted PSC increases from 18.67% to 20.23%. Furthermore, its operational stability is also enhanced. Other than PTAA coupled with organic interlayers, inorganic interlayers have also been studied. PTAA with a thin MoO 3 interlayer on top was reported to give both a higher J SC and FF, benefiting from reduced resistance of carrier extraction. PTAA/CuI HTL was also reported recently, where the CuI benefits the grain quality of the perovskite. The formation of the CTC makes the PTAA conjugated backbone electron-deficient, resulting in a quinoidal and stiffer character, which is likely to planarize the PTAA backbone and enhance the ordering of the film in nanoscale. The resultant HTL exhibits a reduced energy disorder, which simultaneously promotes hole transport in the HTL, hole ...
