We report the synthesis and characterisation of tetra{4-[N,N-(4,4´-dimethoxydiphenylamino)]phenyl}ethene (TAE-1) as efficient and robust hole transport material for its application in methyl ammonium lead iodide (MAPI) perovskite solar cells. The solar cells show light-to-energy conversion efficiencies as high as 11.0% under standard measurement conditions without the need of additional dopants.
