Perovskite metamaterials and metasurfaces

The development of new materials for clean and efficient energy generation and storage is an important area of research that needs to be urgently addressed in modern science due to concerns about global warming, dwindling fossil fuel reserves, and the need for energy security. Perovskite solar cells using methylammonium lead iodide, introduced by Professor Miyasaka et al. in 2009 in the field of solar cells, was selected as one of the most significant scientific breakthroughs of the year by the journals Science and Nature in 2013. I entered this exciting field as a computational chemist in 2012 with Dr. Giacomo Giorgi, one of the editors of this book, and over the past decade, I have been fascinated by the depth of OIHPs as materials, with their chemical diversity, structural diversity, and unique physical properties. It has been a fascinating and exciting field of research. “Halide Perovskites for Photonics” presents the latest experimental and theoretical methodologies for photonic applications of halide perovskites, discusses prospects for future applications, and gives the reader a timely overview of this exciting field. Topics discussed include the following: Chapter 1, Review and future perspectives on photonic applications focusing on the relationship between the nanostructure of halide perovskites and their luminescence properties; Chapter 2, Physicochemical properties of nanostructured halide perovskites and the state of the art in synthesis methods; Chapter 3, Effect of electron doping on electrical properties, such as carrier concentration, conductivity, band structure, and carrier dynamics in perovskite solar cells; Chapter 4, Role of carbon allotropes charge transport layers in improving the performance of perovskite solar cells; Chapter 5, Effect of electron doping on the performance and electrical properties of perovskite solar cells; Chapter 6, Theoretical modeling of photoexcitation dynamics, such as non-radiative relaxation of charge carriers, charge separation, and recombination at interfaces in metal halide perovskites; Chapter 7, Modeling of spontaneous emission and its amplification mechanism in polycrystalline and nanocrystalline films of lead halide perovskites; Chapter 8, Photophysics of defects in solution-processed halide perovskites and their impact on solar cell performance; Chapter 9, Optical properties of two-dimensional layered perovskites and their application to photonic devices; Chapter 10, Recent advances in perovskite nanophotonics and their paradigm with plasmonic and dielectric metamaterials; and Chapter 11, Orbital-free density functional theory and data-driven approaches to plasmonic effects for photonic applications of halide perovskites. I am confident that this book will be an attractive introduction for those who are new to this exciting field and a valuable reference for experienced researchers who are already working on specific materials development and theoretical modeling.
