Dion-Jacobson and Ruddlesden-Popper double-phase 2D perovskites for solar cells

Sajjad Ahmad, Xin Guo, Bowen Yang, Yang Liu, Chen Li

Dion-Jacobson (DJ) phase and Ruddlesden-Popper phase 2D perovskites have been, individually, demonstrated to be more stable than 3D counterparts for perovskite solar cells (PSCs). In order to further improve the efficiency and stability of 2D PSCs, we here ...
