Abstract: Organic-inorganic hybrid perovskite solar cells (PSCs) have recently undergone rapid progress, and since its invention, its photoelectric conversion efficiency (PCE) has been experiencing surprisingly swift and frequently record-breaking growth, and finally reached the present record 23.3%. This makes PSCs an indisputable research hotspot in the field of solar cells. The structure and properties of PSCs have been found significant to the device performance. Moreover, the morphology of electron transport layer not only affects the morphology of perovskite, but also dominates the electron diffusion coefficient and electron lifetime. In this work, zinc oxide nanorod arrays (ZnO NRAs) were firstly applied as the electron transport layer in hole-transport-layer-free, carbon-counter electrode based perovskite solar cells, and in the meanwhile, its feasibility had been confirmed. A series of ZnO NRAs which differ in nanorod length were hydrothermally fabricated. The corresponding PCEs of the solar cells were determined to have a biphasic (increase → decrease) change with the increasing length of ZnO NRAs, and to reach the optimum alue (6.18%) when the length of ZnO NRAs was 454 nm.
