Latest Patents

His latest patents include "Passivation of nanocrystals tailored to different facets, and its application to optoelectronic devices." This patent presents a method for facet-selective passivation on each crystal facet of colloidal nanocrystals through a solution-phase ligand exchange process. This method results in highly-passivated and colloidally-stable nanocrystal inks. The ligand exchange strategy effectively addresses polar and non-polar facets, preventing harmful nanocrystal aggregation in the colloid. The introduction of alkali metal organic complexes during metal halide solution exchanges, such as Na·Ac, stabilizes and passivates non-polar facets while polar facets are passivated through metal halides. This innovative strategy significantly reduces nanocrystal aggregation and enhances photophysical properties.

Another notable patent is for an "Organic solar cell and method for fabricating the same." This invention describes an organic solar cell that includes a photoactive layer where a low molecular weight conjugated compound is mixed with a second organic semiconductor material. The first organic semiconductor material contains both electron donors and electron acceptors, which improves the morphology of the photoactive layer, leading to higher efficiency in the organic solar cell.
