All-Inorganic Metal Halide Perovskite (CsPbX3; X = Cl, Br, I) Nanocrystal-Based Photodetectors

Detecting Visible to Near-Infrared II Light via CsPbBr3 Nanocrystals/Y6 Heterojunctions

“…The advent of perovskite materials, renowned for their outstanding optoelectronic properties, has led to diverse applications across various fields, including high-performance solar cells and advanced photodetectors (PDs). − Perovskite materials can be broadly categorized into organic–inorganic hybrid perovskites and all-inorganic perovskite. Among these, organic–inorganic hybrid perovskites are prone to decay in moist environments due to their organic components.…”

“…2,12 In particular, all-inorganic perovskite colloidal nanocrystals (NCs) or quantum dots (QDs) exhibit considerable potential with their large absorption cross-section, high emission efficiency, elevated charge carrier mobility, and tunable bandgap energies spanning the entire visible (vis) spectral region from 410 to 700 nm. 2,3,13 Additionally, they offer the advantages of a solution process and the ease of preparation for large-scale applications. These advantages make them an ideal candidate for photodetection applications.…”

“…Among these, organic–inorganic hybrid perovskites are prone to decay in moist environments due to their organic components. Conversely, all-inorganic perovskites demonstrate enhanced thermal and moisture stability, − attributed to the absence of inorganic cation components in their molecular structure. , In particular, all-inorganic perovskite colloidal nanocrystals (NCs) or quantum dots (QDs) exhibit considerable potential with their large absorption cross-section, high emission efficiency, elevated charge carrier mobility, and tunable bandgap energies spanning the entire visible (vis) spectral region from 410 to 700 nm. ,, Additionally, they offer the advantages of a solution process and the ease of preparation for large-scale applications.
