Metal halide perovskites have shown promising optoelectronic properties suitable for light-emitting applications. The development of perovskite light-emitting diodes (PeLEDs) has progressed rapidly over the past several years, reaching high external quantum efficiencies of over 20%. In this Review, we fo...
Lead-halide perovskites have entered the family of colloidal nanocrystals, showing excellent optical properties and easy synthesizability. This Review provides an insight into their chemical versatility, stability challenges and use in optoelectronics. ...
Metal halide perovskites (MHPs) are a class of materials with promising properties for semiconductor applications, such as thin-film transistors (TFTs). In particular, tin (Sn)-based MHPs could be an environmentally benign alternative to lead-based ones, which are toxic. However, some critical i...
One such application is light-induced phase segregation where illumination, for example, sunlight, interrupts the cautiously arranged composition of elements inside the mixed-halide perovskites. This, on the other hand, results in instability in the bandgap of the material, interfering with the waveleng...

To find out why the extrinsic metal ions can n-dope the surface of metal halide perovskites, we carried out first-principles computation within the framework of density functional theory (DFT). The surface doping is realized through the additive metal ions on the surface, therefore the simulation...
The light-soaking effect is the observation that under constant illumination the measured power conversion efficiency of certain solar cells changes as a function of time. The theory of the light-soaking in metal halide perovskites is at present incomple
