Diarylamino-substituted Tetraarylethene (TAE) as an Efficient and Robust Hole Transport Material for 11% Methyl Ammonium Lead Iodide Perovskite Solar

Abstract

<p> We report the synthesis and characterisation of tetra{4-[N,N-(4,40 - dimethoxydiphenylamino)]phenyl}ethene (TAE-1) as an 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.</p>
