摘要
The perovskite solar cells have attracted extensive attention recently.To improve the device efficiency, previous works mainly focused on optimizing quality of perovskite films and applying external interface modifiers.Here, we have developed an innovative method with in-situ growth of one-dimensional perovskite nanowire(1D PNW) over the perovskite films via amine Lewis interaction.The 1D PNWs not only passivate the charge traps on the polycrystalline perovskite surface, but also promote charge transport from the bulk perovskite film to the electron transport layer as a fast channel.Consequently, the perovskite solar cells with 1D PNW modification exhibit significantly enhanced short-circuit current density and an improved PCE from 14.32% to 16.66% with negligible hysteresis, as well as higher stability in the ambient air.
