Following the unprecedented rise in photovoltaic power conversion efficiencies during the past five years, metal‐halide perovskites (MHPs) have emerged as a new and highly promising class of solar‐energy materials. Their extraordinary electrical and optical properties combined with the abundance of the raw materials, the simplicity of synthetic routes, and processing versatility make MHPs ideal for cost‐efficient, large‐volume manufacturing of a plethora of optoelectronic devices that span far beyond photovoltaics. Herein looks beyond current applications in the field of energy, to the area of large‐area electronics using MHPs as the semiconductor material. A comprehensive overview of the relevant fundamental material properties of MHPs, including crystal structure, electronic states, and charge transport, is provided first. Thereafter, recent demonstrations of MHP‐based thin‐film transistors and their application in logic circuits, as well as bi‐functional devices such as light‐sensing and light‐emitting transistors, are discussed. Finally, the challenges and opportunities in the area of MHPs‐based electronics, with particular emphasis on manufacturing, stability, and health and environmental concerns, are highlighted. Their extraordinary electrical and optical properties combined with the abundance of their raw materials, have driven metal‐halide perovskites (MHPs) to the forefront of functional electronic materials research, with envisioned applications spanning across several technology sectors. The recent advances in the use of MHPs in the area of transistors and transistor‐related applications are summarized.
