英文摘要	The recent rise of low-dimensional Ruddlesden-Popper (RP) perovskites is notable for superior humidity stability, however they suffer from low power conversion efficiency (PCE). Suitable organic spacer cations with special properties display a critical effect on the performance and stability of perovskite solar cells (PSCs). Herein, a new strategy of designing self-additive low-dimensional RP perovskites is first proposed by employing a glycine salt (Gly(+)) with outstanding additive effect to improve the photovoltaic performance. Due to the strong interaction between C(sic)O and Pb2+, the Gly(+) can become a nucleation center and be beneficial to uniform and fast growth of the Gly-based RP perovskites with larger grain sizes, leading to reduced grain boundary and increased carrier transport. As a result, the Gly-based self-additive low-dimensional RP perovskites exhibit remarkable photoelectric properties, yielding the highest PCE of 18.06% for Gly (n = 8) devices and 15.61% for Gly (n = 4) devices with negligible hysteresis. Furthermore, the Gly-based devices without encapsulation show excellent long-term stability against humidity, heat, and UV light in comparison to BA-based low-dimensional PSCs. This approach provides a feasible design strategy of new-type low-dimensional RP perovskites to obtain highly efficient and stable devices for next-generation photovoltaic applications.
