benzoquinone. Moreover, the introduction of conductive CNT
would facilitate the photo-generated electron-hole pairs
separation, which significantly improves the photocurrent
density. Particularly, it is found that the loading amount should
be carefully optimized since excessive CNT will compete with
perovskite NC in light absorption. In addition, alloying iodide to

result, a highest photocurrent density of 417 μA cm is attained
on the CsPbBr1.5 1.5 NC/CNT (200) sample, corresponding to a
