Perovskite nanostructures for photovoltaic and energy storage devices

Exploring prospective materials for efficient energy production and storage is a big challenge in this century. Numerous research groups working in this field focus on novel materials for such applications and this is reflected in the large number of articles on the topic. At the same time, there has recently been increasing interest in fabricating entirely new types of devices and even exploring new physics, by structuring matter at the nanoscale. Nanostructured materials are acknowledged as viable materials to effectively replace conventional energy materials in such energy applications. Among these nanostructured materials, in this review article we focus on perovskite nanomaterials, such as perovskite oxides and halide perovskites, utilized in high performance energy technologies, including photovoltaics, supercapacitors and batteries. The various approaches used for the fabrication of perovskite nanostructures with centrosymmetric or non-centrosymmetric morphologies are particularly reviewed, while the impact of the structure, morphology, and composition on energy device performance is extensively discussed.
