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 ...

The study of curvature effects on crystal structures and defect dynamics offers pivotal insights into how geometric constraints influence material properties at the micro‐ and nanoscale. Curved ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

Researchers at Università Cattolica, Brescia campus, have discovered that the transition from insulating to conductive behavior in certain materials is driven by topological defects in the structure.

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

Insights into atomic-scale defects may enable next-generation thin-film transistors for smartphones, televisions, and flexible electronics. (Nanowerk News) Many displays found in smartphones and ...

A new hybrid layered perovskite featuring elusive spontaneous defect ordering has been found, report scientists. By introducing specific concentrations of thiocyanate ions into FAPbI3 (FA = ...

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 ...

Imagine a "smart fluid" whose internal structure can be rearranged just by changing temperature. In a new study published in ...
