Web10 apr. 2024 · Apart from Cs 3 Bi 2 X 9, double perovskite is also one of the most attracting lead free IMHPs materials. Yb 3+ ions were successfully doped in double perovskite Cs 2 AgInCl 6 soon after. 37 , 43 Double perovskite Cs 2 AgInCl 6 was less attractive owing to its large bandgap (∼3.3 eV), without strong response to visible and infrared light. Web2 dagen geleden · 2D perovskites including Ruddlesden-Popper (RP) phase and Dion-Jacobson (DJ) phase have attracted much interest thanks to their higher structural stability than 3D ones. In principle, DJ 2D perovskites are more stable than RP counterparts owing to bilateral hydrogen bonds between diammonium cations and inorganic octahedra. Webresistance to solvent-stress (perovskite-soluble polar solvents such as DMF) and annealing-stress when perovskite was cast atop.[51] The VNPB crosslinked layer is intrinsic, and thus incapable of efficient hole extraction from the perovskite. We sought to introduce free holes, and to do so without chemical doping used in Spiro-MeOTAD. brave wireless
