제목 Ultrathin atomic layer deposited TiO2 for surface passivation of hydrothermally grown 1D TiO2 nanorod arrays for efficient solid state perovskite solar cells
초록 In the current work, we have studied the effect of the passivation of atomic layer deposited (ALD) ultrathin TiO2 on the hydrothermally grown one dimensional (1D) TiO2 nanorod (NR) arrays for solid state perovskite sensitized solar cells. Different thicknesses of ALD passivated TiO2 were deposited on the hydrothermally grown 1D TiO2 NR samples. The ALD TiO2 thickness was varied from 1nm to 5nm by varying growth cycles. Our controlled results revealed that, the 4nm thin layer passivated TiO2 nanorod sample shows power conversion efficiency (PCE) as high as 12.53% (without masking) for the CH3NH3PbI3 perovskite absorbing layer.
