A study from the Research Center for Materials Nanoarchitectonics (MANA) has uncovered a theoretical mechanism showing how the electronic band structures of strongly correlated insulators can be ...

Tiny crystal “seeds” could solve a hidden flaw in perovskite solar cells—unlocking high efficiency at larger scales.

Regular perovskite solar cells (PSCs)—which place the electron-transport layer beneath the perovskite absorber and the hole-transport layer on top—have limitations with respect to large-scale ...

Defect-filled lead-halide perovskites rival silicon solar cells because domain walls inside the material separate and guide charges. Researchers visualized these charge-transport networks using a ...

Hypothetical dark matter stars known as ‘boson stars’ could leave telltale ripples across the cosmos, offering researchers a new way to probe the invisible forces shaping the universe. By Jonathan ...

Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current.

Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching ...

Researchers at the University of New South Wales (UNSW) School of Photovoltaic and Renewable Energy Engineering (SPREE) have filed patent protection and are working to scale production of a new class ...

Excitons, bound states between an electron (i.e., a negatively charged particle) and a hole (i.e., the absence of an electron) in materials, are a key focus of condensed matter physics studies. These ...

Scientists directly observed tiny lattice deformations in quantum dots caused by electron-hole pairs, key for advancing solar cells and LEDs. (Nanowerk News) When light hits solar cells, so-called ...
