Core-shell quantum dots CdSe/ZnS and lumogen yellow organic dye are characterized by their inclusion in luminescent downshifting (LDS) layers. Layers were deposited on top of crystalline silicon cell (c-Si), synthesized solar (DSSC), cadmium telluride (CdTe) minimodules. External efficiency measurements for the cell/LDS devices discussed. Experimental results compared with an optical model developed Rothemund, 2014.

Quantum Dot Solar Concentrators (QDSCs) are static, non-imaging concentrators which do not require expensive solar tracking and concentrate both direct diffuse light. Optical efficiencies (η<sub>opt</sub>) concentration ratios (C) of a single plate QDSC were calculated by Monte-Carlo ray-trace modelling. Consideration reflection, refraction, quantum dot (QD) photon emission absorption light attenuation in the device matrix included analysis. In this paper, effect placing plane reflectors...
The quantum dot solar concentrator optical efficiency is undermined by the parameters of re-absorption, scattering, and escape cone losses. These losses can be address through enhancing (QDs) absorption emission.

Abstract We report the first visible-light-promoted synthesis of vinyloxaziridines from simple conjugated nitrones. have found that vinyl nitrones formed by condensation reaction between carbonyls and hydroxylamines undergo energy-transfer isomerization to respective in very high yields selectivities. The scope expands a large array substitution patterns, evidence indicates proposed pathway is predominant mechanism for this transformation.
A Monte-Carlo ray-trace model has been developed which allows the calculation of optical efficiency (ηopt) and concentration ratio (CR) values a Quantum Dot Solar Concentrator (QDSC). In this paper, ηopt have calculated using range material refractive indices, attenuation coefficients, quantum dot (QD) efficiencies (QE).
