Formamidinium-lead-iodide (FAPbI3) has established itself as the state of the art for high solar-energy conversion efficiency in perovskite-based solar cells. FAPbI3 has a rich phase diagram, and it has been noted that long-range correlation between organi ...

Layered (2D) hybrid perovskites offer a promising alternative for stabilizing halide perovskite materials, with a growing interest in formamidinium (FA(+)) lead iodide derivatives for photovoltaics due to their exceptional optoelectronic properties. While ...

A-site cation mixing can enhance the photovoltaic performance of a wide-bandgap (WBG) perovskite, but rubidium (Rb) cation mixing generally forms a nonperovskite phase. We report that lattice strain locks Rb ions into the α-phase of the lattice of a triple ...

Microchannels hosting spatially-periodic supports for the stationary phase have drawn intense attention in Liquid Cromatography (LC) research in the last two decades, with second-generation μPACs (micro-pillar array columns) setting the current limit of se ...

The stability of hybrid organic-inorganic halide perovskite semiconductors remains a significant obstacle to their application in photovoltaics. To this end, the use of low-dimensional (LD) perovskites, which incorporate hydrophobic organic moieties, provi ...

Lead halide perovskite light-emitting diodes (PeLEDs) have demonstrated remarkable optoelectronic performance1-3. However, there are potential toxicity issues with lead4,5 and removing lead from the best-performing PeLEDs-without compromising their high ex ...

Monolithic all-perovskite tandem solar cells present a promising approach for exceeding the efficiency limit of single-junction solar cells. However, the substantial open-circuit voltage loss in the wide-bandgap perovskite subcell hinders further improveme ...
