Abstract
? 2022 Elsevier B.V.The core-shell quantum dots (CSQDs) are three-dimensional (3D) confined semiconductor nanoparticles that are widely researched to accommodate the needs of modern-day applications. In addition to chemical stability, the shape, size, and surface modification of CSQDs play a vital role in the carrier confinement resulting in a wide range of optoelectronic applications such as solar cells, light-emitting diodes (LEDs), luminescent solar concentrators (LSCs), etc. The current review highlights the classifications and applications of CSQD systems based on semiconductor materials. The aspects related to the characterization, properties, and theoretical modeling of colloidal semiconductor CSQDs focusing on the role of the shell have been presented. Also, the altering of bandstructure from the viewpoint of lattice-mismatched strain, carrier dynamics, and its application in optoelectronic devices has been highlighted. Further, the article emphasized the different techniques used for theoretical modeling of the different shaped CSQD systems. To conclude, the article discussed in detail the recent progress in the theoretical modeling of quantum dot solar cells (QDSCs) using the detailed balance model and its limitations based on modification in the recombination current density.
