“…The outcomes show that phosphorus rich in electrons may function as a great core unit in the perovskite absorber layer to passivate surface imperfections for better crystallization and charge transport characteristics. Owing to the passivation effect of P-CQDs on perovskite films, appropriate energy band gap values, and optical characteristics of the MAPbI 3 layer, the device prepared with the addition of 5 vol % of P-CQDs achieved a high fill factor (FF) of 73.44% and a champion power conversion efficiency (PCE) of 13.12%, surpassing the PCE of 10.71% and FF of 58.81% for the control device . Masfer Alkahtani et al combined and added carbon quantum dots (CQDs) and upconversion nanoparticles (UCNPs) at the proper mixing ratios to the layers of perovskite solar cells (PSCs) (Figure A).…”

The manufactured PSCs demonstrated stronger photocurrent, better fill factor (FF), and enhanced power conversion efficiency (PCE) from 16.57% to 20.44% as compared to the pristine PSCs.…”

Carbon nanodots (CNDs), a fascinating carbon-based nanomaterial (typical size 2−10 nm) owing to their superior optical properties, high biocompatibility, and cell penetrability, have tremendous applications in different interdisciplinary fields. Here, in this Review, we first explore the superiority of CNDs over other nanomaterials in the biomedical, optoelectronics, analytical sensing, and photocatalysis domains. Beginning with synthesis, characterization, and purification techniques, we even address fundamental questions surrounding CNDs such as emission origin and excitation-dependent behavior. Then we explore recent advancements in their applications, focusing on biological/biomedical uses like specific organelle bioimaging, drug/gene delivery, biosensing, and photothermal therapy. In optoelectronics, we cover CND-based solar cells, perovskite solar cells, and their role in LEDs and WLEDs. Analytical sensing applications include the detection of metals, hazardous chemicals, and proteins. In catalysis, we examine roles in photocatalysis, CO 2 reduction, water splitting, stereospecific synthesis, and pollutant degradation. With this Review, we intend to further spark interest in CNDs and CND-based composites by highlighting their many benefits across a wide range of applications.
