| 英文摘要 | compared to the fast electron transport in perovskite and rapid electron injection from perovskite to tio2 nanoparticle scaffold, the slower electron transport rate in mesoporous tio2 is reported to be a hindrance factor for power conversion efficiency. one-dimensional nanomaterials are believed to show faster carrier transport rate. in this paper, vertically aligned one-dimensional tio2 nanocones on transparent conducting oxide were synthesized and utilized as a promising scaffold for perovskite solar cells. a simple concentration-dependent ch3nh3pbi3 seeding spin-coating method was developed to effectively improve the surface coverage at low cost. the resultant perovskite solar cells realized an average power conversion efficiency up to 11%, which is higher than that of rectangular tio2 nanorods-based device. besides the faster electron transport rate and slower recombination in such one-dimensional nanostructures, we attribute the superior performance of the nanocone-based device to the fact tio2 nanocone arrays allow more ch3nh3pbi3 to deposit. by scaling up the nanocone-based devices to 1.2 cm(2), they yielded a decent average power conversion efficiency of similar to 6%. the combination of tio2 nanocones with perovskite paves a way to take full advantage of one-dimensional nanomaterials and organic-inorganic perovskites for photovoltaic applications. |
