Special Issue Information

Dear Colleagues,

Hybrid organic–inorganic perovskites triggered an impressive excitement in the field of photovoltaics since the first evidence of efficient use of MAPbI3 as absorber in 2009. The search for new materials and photovoltaics cell architectures pushed the efficiency of perovskite-based solar cells to 22.1% in 2016. At the same time, analogous materials and new fully inorganic perovskites were shown to be excellent candidates for optical applications, such as light-emitting diodes and lasers. All these experimental achievements, together with theoretical modelling, opened several questions and concerns that still need to be solved, such as the long-term stability of perovskite solar cells, the presence of toxic lead, the ion migration issue, etc. The actual state-of-the-art, on both device design and materials chemistry, is quite mature, but efforts should be made in order to solve the above-mentioned, and other issues. Other important aspects to be considered are the characterization methods of solar cell performance and the fundamental physical and chemical properties of these materials. This Special Issue aims at collecting papers that review the actual status and future directions of hybrid organic–inorganic perovskites topic, from both basic and applied points of view, as well research papers reporting new achievements in this field.

Cation tracer diffusion in polycrystalline AZrO3 (A = Ca, Sr, Ba) perovskites was studied at 1300–1500 °C in air using the stable isotope 96Zr. Thin films of 96ZrO2 were deposited on polished ceramic pellets by drop casting of an aqueous precursor solution containing the tracer. The pellets were subjected to thermal annealing, and the isotope depth profiles were measured by secondary ion mass spectrometry. Two distinct regions with different slopes in the profiles enabled to assess separately the lattice and grain boundary diffusion coefficients using Fick’s second law and Whipple–Le Clair’s equation. The cation diffusion along grain boundaries was 4–5 orders of magnitude faster than the corresponding lattice diffusion. The magnitude of the diffusivity of Zr4+ was observed to increase with decreasing size of the A-cation in AZrO3, while the activation energy for the diffusion was comparable 435 ± 67, 505 ± 56, and 445 ± 45 and kJ·mol−1 for BaZrO3, SrZrO3, and CaZrO3, respectively. Several diffusion mechanisms for Zr4+ were considered, including paths via Zr- and A-site vacancies. The Zr4+ diffusion coefficients reported here were compared to previous data reported on B-site diffusion in perovskites, and Zr4+ diffusion in fluorite-type compounds. Full article
