Ruddlesden–Popper Perovskites: Energetics and Energy Loss in 2D Ruddlesden–Popper Perovskite Solar Cells (Adv. Energy Mater. 23/2020)

In article number 2000687, Qinye Bao and co-workers systematically investigate the energetics and energy loss in 2D Ruddlesden-Popper perovskite (RPP) solar cells. The crucial scenario found at the 2D RPP/electron transport layer interface is that the potential gradient across ligands promotes separation of the photogenerated carrier, with electrons transferring from the perovskite crystal to the electron transport layer.
