Abstract: Methods for depositing a metal containing material formed on a certain material of a substrate using an atomic layer deposition process for semiconductor applications are provided. In one embodiment, a method of forming a metal containing material on a substrate comprises pulsing a first gas precursor comprising a metal containing precursor to a surface of a substrate, pulsing a second gas precursor comprising a silicon containing precursor to the surface of the substrate, forming a metal containing material selectively on a first material of the substrate, and thermal annealing the metal containing material formed on the substrate.

Abstract: Luminescent solar concentrators in accordance with various embodiments of the invention can be designed to minimize photon thermalization losses and incomplete light trapping using various components and techniques. Cadmium selenide core, cadmium sulfide shell (CdSe/CdS) quantum dot (“QD”) technology can be implemented in such devices to allow for near-unity QDs and sufficiently large Stokes shifts. Many embodiments of the invention include a luminescent solar concentrator that incorporates CdSe/CdS quantum dot luminophores. In further embodiments, anisotropic luminophore emission can be implemented through metasurface/plasmonic antenna coupling. In several embodiments, red-shifted luminophores are implemented. Additionally, top and bottom spectrally-selective filters, such as but not limited to selectively-reflective metasurface mirrors and polymeric stack filters, can be implemented to enhance the photon collection efficiency. In some embodiments, luminescent solar concentrator component is optically connected in tandem with a planar Si subcell, forming a micro-optical tandem luminescent solar concentrator.
