文摘
A triphenylamine based molecular “butterfly” is developed as dopant-free hole-transport material for perovskite solar cells exhibiting excellent power conversion efficiency of 16.3% which is comparable to the state-of-the-art doped 2,2′,7,7′-tetrakis(N,N′-di-p-methoxy-phenylamine)-9,9′-spirobifluorene (spiro-OMeTAD). Moreover, the device is much more stable than that of spiro-OMeTAD based device under light irradiation.
