“…PL quantum yields (PLQY) were measured with the Labsphere integrating sphere explained in our previous works. 14,18 To check the validity of our PLQY measurements, we used Nanolumi CsPbBr 3 quantum dots as references as they had already been measured previously by the company. 14,18 All optical measurements were performed after a pre-heating step so that there was no afterglow or traps in the samples.…”

“…Moreover, replacing the lead cation with other divalent cations may increase the Stokes shift of the materials. 7 An approach to replace lead with other metal cations has been attempted such as with manganese (Mn), 12 copper (Cu), 13 tin (Sn), 14 and antimony (Sb). 15 In this work, we aim to explore the effect of Pb substitution by Cu or Sn on the optical and scintillation properties of solution-processed 2D BA 2 PbBr 4 perovskite.…”

Hybrid Organic–Inorganic Perovskite Halide Materials for Photovoltaics towards Their Commercialization

Hybrid organic–inorganic perovskite (HOIP) photovoltaics have emerged as a promising new technology for the next generation of photovoltaics since their first development 10 years ago, and show a high-power conversion efficiency (PCE) of about 29.3%. The power-conversion efficiency of these perovskite photovoltaics depends on the base materials used in their development, and methylammonium lead iodide is generally used as the main component. Perovskite materials have been further explored to increase their efficiency, as they are cheaper and easier to fabricate than silicon photovoltaics, which will lead to better commercialization. Even with these advantages, perovskite photovoltaics have a few drawbacks, such as their stability when in contact with heat and humidity, which pales in comparison to the 25-year stability of silicon, even with improvements are made when exploring new materials. To expand the benefits and address the drawbacks of perovskite photovoltaics, perovskite–silicon tandem photovoltaics have been suggested as a solution in the commercialization of perovskite photovoltaics. This tandem photovoltaic results in an increased PCE value by presenting a better total absorption wavelength for both perovskite and silicon photovoltaics. In this work, we summarized the advances in HOIP photovoltaics in the contact of new material developments, enhanced device fabrication, and innovative approaches to the commercialization of large-scale devices.

Inorganic scintillators play a pivotal role in diverse fields like medical imaging, nondestructive detection, homeland security, and high‐energy physics. However, traditional inorganic scintillators encounter challenges such as high fabrication costs and low light yield. Recently, low‐dimensional metal halide scintillators (LDMHS) have witnessed rapid progress, owing to their distinctive crystal structure and superior radioluminescence performance. Herein, an overview of recent advancements and proposed instructive pathways for achieving high‐performance LDMHS is provided. First, the scintillation physical mechanism and emphasis on the essential requirements of scintillators for diverse applications are elucidated. Furthermore, LDMHS by the B‐site, introducing recent advancements and providing insights into their characteristics is categorized. This encompasses the understanding of structure‐property relationships and the routes and rules for optimizing scintillation performance. Finally, the persisting challenges in this burgeoning field and proposed potential research directions for future exploration are discussed.
