Perovskite Oxides for Energy Applications

Industrial and population growth is constantly increasing energy consumption. Since 81.3% of consumed energy is produced from fossil fuels, the high pollution and emission rates are leading to climate changes resulting in extreme weather conditions. The development of new materials and technology is necessary to achieve sustainable societal growth and development. In the field of new materials, perovskites are the main subject of much scientific research conducted in the last decade. Perovskites are usually divided into two groups: halides and oxides. The application of perovskite halides in photovoltaic and solar cells is already well-known and investigated. On the other hand, perovskite oxides do not possess optical and light-absorption properties comparable to perovskite halides, but they have promising electrical and magnetic properties and high reducibility rates. This review is dedicated to the perovskite oxides, preparation methods of this material and their application for energy transformation and storage applications. The perovskite oxides have high potential as working materials in solid oxide fuel cells (SOFC), Ca batteries, thermochemical energy storages (TCES) and ambient temperature magnetic refrigerators (MR).
