Special Issue Information

Dear Colleagues,

Metal halide perovskites have emerged as a class of semiconductors materials with unique optoelectronic properties, which enable a broad range of energy-related applications. Since the first application, the photoconversion efficiencies have been boosted up to 25% within a few years, but to go toward the commercialization, the scientific community is focusing the efforts on the contemporary challenges associated with the limited operational stability of hybrid perovskites, and on the replacement of lead (Pb) with less toxic metals, commonly tin (Sn). This Special Issue of Nanomaterials aims to publish original research papers and review articles directing on the innovative synthesis and application of stable and/or lead-free perovskite, in the form of methylammonium-free perovskite, nanocomposite perovskite-additives, 2D and quantum dots, in order to understand the fundamental degradation mechanisms and address them. Recent advances in towards deepening the understanding of the nature of instabilities in hybrid perovskite materials and the corresponding devices from the perspective of structural properties and optoelectronics as well as device operation will be covered.

In this Special Issue, we aim at providing a timely perspective on the advances in perovskite optoelectronics, related to the stabilization strategies. Topics to be covered include (but are not limited to):

  • Chemi-structural strategies to stabilize hybrid perovskites
  • Low-dimensional perovskites towards stable devices
  • Stability of hybrid perovskite devices under real-world operation conditions
  • Lead-free stable perovskite synthesis and optical properties
  • Advanced optoelectronic devices (solar cells, LEDs)
  • Photocatalysis

Experimental and theoretical contributions are both welcome.

Accepted papers are published in the joint Special Issue in Nanomanufacturing or Nanomaterials (https://www.mdpi.com/journal/nanomaterials/special_issues/Nano_Optoele_Perov).

The study of the solvent-mediated structural evolution mechanism of the Cs4PbBr6 powders prepared using the solvothermal method is presented. The Cs4PbBr6 powders with a rhombohedral structure and an intense green emission (i.e., mainly due to the presence of complex defect states in the forbidden gap), which is stable in its solid-state form, but a distinct behavior is observed in different dispersions, easily detectable when irradiated with ultraviolet (UV) light. Depending on the polarity of the solvent, a change in the emission color from green to red is observed, easily detectable when irradiated with ultraviolet (UV) light. Our findings suggest that the solvent polarity affects the surface decomposition process, leading to a different change in composition, structure and crystal shape. This peculiar behavior plays a pivotal role in the control of the properties of Cs4PbBr6, and this study, therefore, offers a fundamental understanding needed for Cs4PbBr6 potential future applications.
