Perovskite solar cells have the potential to revolutionize the world of photovoltaics, and their efficiency close to 23 % on a lab-scale recently certified this novel technology as the one with the most rapidly raising performance per year in the whole story of solar cells. With the aim of improving stability, reproducibility and spectral properties of the devices, in the last three years the scientific community strongly focused on Cs-doping for hybrid (typically, organolead) perovskites. In parallel, to further contrast hygroscopicity and reach thermal stability, research has also been carried out to achieve the development of all-inorganic perovskites based on caesium, the performances of which are rapidly increasing. The potential of caesium is further strengthened when it is used as a modifying agent of charge-carrier layers in solar cells, but also for the preparation of perovskites with peculiar optoelectronic properties for unconventional applications (e.g., in LEDs, photodetectors, sensors, etc.). This Review offers a 360-degree overview on how caesium can strongly tune the properties and performance of perovskites and relative perovskite-based devices.

“…Recently, hybrid halide perovskites have drawn increasing attention for high‐performance optoelectronic devices due to their unprecedented light‐to‐electricity conversion efficiencies . Generally, halide perovskites have ABX 3 crystal structures ( Figure a), where A is an organic or inorganic cation (i.e., CH 3 NH 3 + (MA), HC(NH 2 ) 2 + (FA), or Cs + ), B is a metal cation (i.e., Pb 2+ or Sn 2+ ), and X is a halide anion (i.e., Cl − , Br − , I − , or their mixtures), with tunable bandgap through varying the halide composition .…”

Based on the understanding and control of the energy levels and density of defect states of 0D, 1D, 2D, and 3D materials, halide perovskite photodetectors (HPPDs) based on different dimensional materials have recently gained significant achievements. In addition, the detection range of HPPDs even extended from ultraviolet–visible–near infrared (UV–vis–NIR) to X/γ photons, and the self‐powered HPPDs also became a hot issue. In this review, a comprehensive summary of the recent advances in HPPDs based on different dimensional materials is proposed, including 0D, 1D, 2D, and 3D perovskite and nonperovskite (without perovskite ABX3 crystal structure) materials, focusing on the relationship among the charge‐carrier transport, operation mechanism, device architectures, and photodetecting performances. First, an introduction of composition and crystal structures of HPPDs is given, followed by the description of their key figure‐of‐merit parameters evaluation system. Next, the recent developments of HPPDs based on different dimensional materials are highlighted. And finally, the characteristics of HPPDs depending on the dimensionality are summarized, and the potential challenges and approaches for future study are also presented.
