QUANTUM DOTS: APPLICATIONS IN BIOIMAGING AND SOLAR CELLS
Keywords:
Quantum Dots, Bioimaging, Solar Cells, Photostability, Light Absorption, Multiple Exciton Generation, Semiconductor NanoparticlesAbstract
Quantum dots (QDs) are semiconductor nanoparticles with unique optical and electronic properties resulting from quantum confinement effects. This paper explores the applications of quantum dots in two critical areas: bioimaging and solar cells. In bioimaging, QDs offer enhanced imaging capabilities due to their size-tunable fluorescence, broad absorption spectra, and high photostability. In solar cells, QDs can be used to improve light absorption, enhance charge carrier dynamics, and facilitate multiple exciton generation. This review summarizes recent advancements, highlights key challenges, and suggests future research directions in these applications.
