Written by respected experts and researchers working on ICT, the book offers a valuable asset for young researchers involved in advanced studies. The work is presented in four volumes.

Perovskite Materials and Devices A comprehensive overview of the important scientific and technological advances in commercialization of this important mineral Perovskite has held much interest for scientists and industrialists, as the mineral is abundantly available in nature. Due to the intriguing and unusual physical properties of perovskite materials—the high-absorption coefficient, low exciton-binding energy, and high dielectric constant, for example—there has been substantial focus on perovskite’s potential in applications. In particular, they have been of great use in sensors and catalyst electrodes, certain types of fuel cells, solar cells, lasers, memory devices, and spintronics, and as a result hold exciting opportunities for physicists, chemists, and material scientists alike. Perovskite Materials and Devices comprehensively covers all the milestone work in perovskites research, systematically introducing the properties, methods, and technologies associated with the mineral from fundamentals to promising applications to commercialization issues. The book focuses on traditional and novel electronic operations, such as solar cells, LEDs, lasing, photodetectors, X-ray detectors, transistors, and more. It also investigates ways to make the use of such materials more environmentally friendly, which in turn can make perovskite minerals more commercially viable. Perovskite Materials and Devices readers will also find Summaries of the latest state-of-the-art developments and technologies, such as perovskite nanocrystals and novel electronic devices Detailed discussion of organic/inorganic hybrid perovskites, all-inorganic perovskite CsPbX3, and lead-free halide perovskites Investigation of the photovoltaic applications, namely single-crystal devices, tandem cells, integrated devices, semi-transparent devices, and flexible devices Description of large-area module fabrication and stability investigating Perovskite Materials and Devices is a useful reference for materials scientists, solid state physicists and chemists, surface physicists and chemists, and electronic engineers. It is also an ideal resource for libraries that supply these fields.

Modern power and energy systems are characterized by the wide integration of distributed generation, storage and electric vehicles, adoption of ICT solutions, and interconnection of different energy carriers and consumer engagement, posing new challenges and creating new opportunities. Advanced testing and validation methods are needed to efficiently validate power equipment and controls in the contemporary complex environment and support the transition to a cleaner and sustainable energy system. Real-time hardware-in-the-loop (HIL) simulation has proven to be an effective method for validating and de-risking power system equipment in highly realistic, flexible, and repeatable conditions. Controller hardware-in-the-loop (CHIL) and power hardware-in-the-loop (PHIL) are the two main HIL simulation methods used in industry and academia that contribute to system-level testing enhancement by exploiting the flexibility of digital simulations in testing actual controllers and power equipment. This book addresses recent advances in real-time HIL simulation in several domains (also in new and promising areas), including technique improvements to promote its wider use. It is composed of 14 papers dealing with advances in HIL testing of power electronic converters, power system protection, modeling for real-time digital simulation, co-simulation, geographically distributed HIL, and multiphysics HIL, among other topics.

This book addresses the rapidly developing class of solar cell materials and designed to provide much needed information on the fundamental principles of these materials, together with how these are employed in photovoltaic applications. A special emphasize have been given for the space applications through study of radiation tolerant solar cells. This book present a comprehensive research outlining progress on the synthesis, fabrication and application of solar cells from fundamental to device technology and is helpful for graduate students, researchers, and technologists engaged in research and development of materials.

This book constitutes selected revised and extended papers from the 10th International Conference on High-Performance Computing Systems and Technologies in Scientific Research, Automation of Control and Production, HPCST 2020, Barnaul, Russia, in May 2020. Due to the COVID-19 pancemic the conference was partly held in virtual mode. The 14 full papers presented in this volume were thoroughly reviewed and selected form 51 submissions. The papers are organized in topical sections on hardware for high-performance computing and its applications; information technologies and computer simulation of physical phenomena.
