| 英文摘要 | 2D Ruddlesden-Popper (2DRP) perovskites with hydrophobic bulky cations are proven to improve the environmental stability in photovoltaic devices significantly. However, these spacer cations lead to a weak interplay in the 2DRP perovskites, severely impacting the charge carrier transport and require a systematic understanding of the interaction between spacer cations and inorganic slabs. Herein, a series of novel perovskites (BA(1-x)NMA(x))(2)MA(3)Pb(4)I(13) (NMA = 1-naphthalenemethylammonium, BA = n-butylammonium) are successfully fabricated to reveal the interaction of mixed spacers and inorganic slabs. Incorporating NMA cations enhances the N-HMIDLINE HORIZONTAL ELLIPSISI- hydrogen-bonding interaction between the spacer cations and [PbI6](4-) slabs, resulting in a preferentially crystal vertical orientation of smoothed perovskite films with larger crystal grains. Thus, a significant reduction in the density of trap states of the resulting 2DRP perovskites is achieved which leads to highly efficient charge carrier transport. Consequently, the champion (BA(0.9)NMA(0.1))(2)MA(3)Pb(4)I(13) device yields a power conversion efficiency (PCE) of 14.21%, along with the unencapsulated devices that can retain 85% of their initial PCE for 1200 h under 35-65% relative humidity conditions. This work provides a simple and original method to modulate the interlayer interplay in 2DRP perovskites for highly efficient and air-stable perovskite solar cells. |
