The outstanding properties of perovskites have brought them to the forefront of emerging new materials in photovoltaics, rapidly approaching the performances of already well-established silicon technology, with the potential to revolutionise from a scientific and technological point of view. Nonetheless, the benefits of perovskites go far beyond photovoltaics stretching towards emitting devices, sensors, memristors or transistors, weaving a network of knowledge around a single material. In this review we highlight these other applications, focusing on the use of perovskites in the fields of lasers, light-emitting diodes and sensors. Recent emerging technologies aimed at space applications, gamma-ray detection, thermochromic devices, storing data and colloidal systems for liquid crystal devices are also included here, contributing to a wider understanding of the extraordinary versatility that lies behind the simple ABX3 structure.
