Thermal history controls the optoelectronic response of lead halide perovskites through structure and dynamics
Milos Dubajic, Xia Liang, Johan Klarbring +26
Lead halide perovskites are promising optoelectronic materials for photovoltaics, light emission and detection. Their efficiencies in PV now approach the detailed-balance limit, le…
Mitigating Singlet Exciton Back-Transfer using 2D Spacer Layers for Perovskite-Sensitised Upconversion
Nicholas P. Sloane, Damon M. de Clercq, Md Arafat Mahmud +7
Photon upconversion has potential applications in light-emitting diodes, photocatalysis, bio-imaging, microscopy, 3D printing, and photovoltaics. Bulk lead-halide perovskite films…
Revealing localised dark-exciton populations in 2D perovskites via magneto-optical microscopy
Christopher G. Bailey, Adrian Mena, Tik Lun Leung +5
The successful development of optoelectronic devices is contingent on a detailed understanding of interactions between light and excited energy states in photoactive materials. In…
Increased resistance to photooxidation in Dion-Jacobson lead halide perovskites -- implication for perovskite device stability
Zhilin Ren, Juraj Ovčar, Tik Lun Leung +24
2D metal halide perovskites have enabled significant stability improvements in perovskite devices, particularly in resistance to moisture. However, some 2D perovskites are even mor…
