This book will provide readers with a good overview of some of most recent advances in the field of technology for perovskite materials. There will be a good mixture of general chapters in both technology and applications in opto-electronics, Xray detection and emerging transistor structures. The book will have an in-depth review of the research topics from world-leading specialists in the field. The authors build connections between the materials' physical properties to the main applications such as photovoltaics, LED, FETs and X-ray sensors. They also discuss the similarities and main differences when using perovskites for those devices.

Perovskite is a calcium titanium oxide mineral, with the chemical formula of CaTiO3. The terms “perovskite” and “perovskite structure” are often used interchangeably, but while true perovskite (the mineral) is formed of calcium, titanium, and oxygen in the form CaTiO3, the perovskite structure is anything that has the generic form ABX3 and the same crystallographic structure as perovskite mineral. Perovskite’s potential applications include catalyst electrodes, solar cells, lasers, memory devices, X-ray and gamma ray sensors, and spintronic applications. The book covers these applications in more depth in the following chapters, so the intent here is to provide some general guidance. Several chapters in various books and review papers can be referenced for earlier reports on perovskite materials.

Depending on the composition, perovskites can have an impressive array of interesting properties including wide bandgap tunability, nonlinear optics, ferroelectricity, charge ordering, spin-dependent transport, and others. Perovskites, therefore, hold exciting opportunities for physicists, chemists, and material scientists. Over the last two decades, halide perovskites (HPs) have been identified as one of the most promising materials in photovoltaic and light-emitting devices. This has led to major breakthroughs in materials science.

Recent advances in halide perovskite materials have resulted in impressive gains in solar cells, photon detectors, and light-emission diodes. This chapter briefly reviews recent advancements in perovskite materials for high-energy photon sensing and contrasts them against state-of-the-art semiconductors, as well as conventional scintillators. A new startup company Actinia is described as a case study. Solar cells are currently the most prominent perovskite application, as perovskites are recognized as potential inexpensive base materials for high-efficiency commercial photovoltaics.
