The article discusses the discovery of ordered columnar defects in a hybrid layered perovskite material by introducing thiocyanate ions into FAPbI3. These defects take up one-third of the lattice space and could lead to innovative strategies for adjusting the properties of hybrid perovskites, potentially advancing optoelectronics and energy generation.
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 = formamidinium), they observed that ordered columnar defects appeared in the stacked crystalline layers, taking up one-third of the lattice space. These findings could pave the way to an innovative strategy for adjusting the properties of hybrid perovskites, leading to practical advances in optoelectronics and energy generation.
