Blade-coating of a highly crystallized lead-free silver-bismuth halide double perovskite thin film with improved stability for high-performance photodetection

Abstract

Lead-free double perovskite (Cs2AgBiBr6) has recently attracted intense interest for optoelectronic applications owing to its non-toxicity, high stability, and high detection sensitivity. The current goal for the commercial application of...

Synthesis and Optimization of Cs2B′B″X6 Double Perovskite for Efficient and Sustainable Solar Cells

“…However, the research time of Cs 2 B′B″X 6 double perovskite is still relatively short. At present, it mainly focuses on blade coating for large areas [ 69 ]. The main process drops the precursor solution on the substrate, quickly scrapes it with a glass blade to form a wet film, and then anneals to obtain a pure-phase film with an area of 10 cm 2 .…”

Understanding the polaron behavior in Cs2CuSbCl6 halide double perovskite

“…1–6 These qualities have made them increasingly popular in applications such as solar cells, X-ray detectors, photodetectors, and photocatalysts. 7–10 Achieving high-performance for these applications often requires the use of high-quality perovskite single crystals (SCs). To this end, a variety of techniques such as surface treatment, crystal annealing, additive engineering, and interface engineering have been implemented to optimize the performance of A 2 MM′X 6 SC-based detectors.…”
