Recent Progress in Mixed A‐Site Cation Halide Perovskite Thin‐Films and Nanocrystals for Solar Cells and Light‐Emitting Diodes

“…[6,187,188] Recently, the use of ligand-protected colloidal LHP NCs, especially CsPbI 3 and FAPbI 3 NCs, as photosensitizers has received increasing attention in the fabrication of PSCs with improved stability under long-term device operation. [14,47,61,62,160,[189][190][191][192][193][194] Importantly, it has been found that the LHP NC-based solar cells exhibit higher open-circuit voltage (V OC ) compared to their thin-film photovoltaics. [61,195] This was attributed to the reduced non-radiative recombination in perovskite NC solar cells and thus leading to smaller V OC losses relative to their bulk counterparts.…”

Introductory Chapter: The Fame of Quantum Dots in Space-age Improvements for Multifunctional Application

“…Perovskite quantum dots (PQDs) have captured an innovative impression that is exploited to improve the photovoltaic performance of numerous kinds of solar cells and summarized some challenges and perspectives concerning of PQDs [60]. The latest innovations in perovskite technology via diverse schemes, such as the amplify its functionality of methodological procedures, surface amendments, and solid QD inks near the device manner engineering for accomplishing sophisticated PV efficiency and enhanced longstanding steadiness [61]. Quantum dots (QDs) make available a multipurpose component to aid the most precise investigative tools and fluoroimmunoassays, dual imaging, multiplexed imaging, therapeutic platforms, real-time in vivo and cellular process imaging, and so on.…”

Cubic CsPbI3 Nanoarchitectonics with High and Stable Photoluminescence toward White Light-Emitting Diodes

“…Cesium lead halide (CsPbX 3 ) perovskite nanocrystals (NCs) are widely applied in the fields of solar cells, photodetectors, liquid crystal televisions, and other optoelectronics − due to their high photoluminescence quantum yields (PLQYs), , narrow spectral widths, tunable PL spectrum in the whole visible light region, adjustable band gaps, and high color purity. − In addition, low-dimensional perovskite NCs have been continuously studied. , However, the surface ligands of these NCs are easily desorbed during the purification process, resulting in the aggregation and growth of NCs into large particles, which decreases the stability and PLQYs . In particular, cesium lead iodide (CsPbI 3 ) NCs can accelerate degradation under the conditions of water, heat, and strong light.…”
