Semiconductor nanocrystal quantum dots have attracted more and more interests in solar cell, solid-state lighting, and biological labeling fields due to the unique size-tunable light absorption and emission properties. Because of the unique properties of the 2d perovskite materials, the corresponding colloidal nanocrystal is attractive to be developed and investigated to understand their optical properties for future highly luminescent and stable colloidal perovskite nanocrystals. The work is further in collaboration with the optoelectronic materials section of prof laurens siebeles at tu delft, who will employ another phd student with focus on carrier multiplication in these 2dlms, and the functional materials research group at toyota that will develop solar cell designs. 2d materials for optoelectronic & energy applications: unyong jeong: pohang university of science and technology, korea designing new functional materials by colloidal nanocrystal assembly: woo-young shim: new post-device treatment to heal defects of perovskite for improving solar cell efficiency by almost an order of magnitude: taeshik. The vast majority of studies on iv-vi nanomaterial-based solar cells concern the so-called colloidal qd solar cells these colloidal qds can be implemented in a schottky junction solar cell in which the p-type (n-type) qds are in contact with a metal with low (high) work function, or in a p-n junction solar cell.
Cesium lead halide perovskite nanocrystals are being lately explored for optoelectronic applications due to their emission tunability, high photoluminescence quantum yields, and narrow emission bands.

Advanced architecture for colloidal pbs quantum dot solar cells exploiting a cdse quantum dot buffer layer we introduce a cdi2-treated cdse quantum dot buffer layer at the junction between zno nanoparticles and pbs quantum dots to improve the performance of the solar cell devices.
As icrea prof at icfo gerasimos konstantatos concludes, “this is the first efficient inorganic nanocrystal solid-state solar cell material that simultaneously meets demands for non-toxicity, abundance and low-temperature solution processing. Quantum dot in hybrid solar cells colloidal quantum dots are also used in inorganic/organic hybrid solar cells these solar cells are attractive because of the potential for. Gain control over macroscopic optoelectronic properties of polymer/nanocrystal composites by mediating their non-covalent interactions via ligands’ pending moieties, thus opening new possibilities towards efficient solution-processed hybrid solar cells.
A solar cell that relies exclusively on colloidal nanocrystals and has good efficiency and reliable stability will help to break the barriers associated with widespread commercialization of inexpensive photovoltaic devices. A multidisciplinary approach for the production and characterization of colloidal quantum dots, which show great promise for implementation in modern optoelectronic applications, is described. A colloidal dispersion is a system in which particles of colloidal size of anynature (eg solid, liquid or gas) are dispersed in a continuous phase of a different composition (or state.
