Quantum dot sensitized solar cell design with surface passivized CdSeTe QDs

Solar Energy, 2020
Abstract One of the main factors affecting the performance of quantum dot sensitized solar cells (QDSSCs) is charge recombination caused by surface traps. It is important to passivize the surface traps of the synthesized QDs as much as possible in order to raise the power conversation efficiency (PCE).

Quantum dots transparent display (QDs-TPD) using a liquid QDs layer and N2 barrier discharge [PDF]

AIP Advances, 2017
Quantum dots transparent display (QDs-TPD) was realized using a liquid QDs layer and N2 barrier discharge panel. In the N2 discharge, the 2nd+ lines of N2 in the range of 300 - 400 nm (C3Πu – B3Πg), and the 1st- lines of N2+ at 391.4 and 427.8 nm (B2Σu+ - X2 Σg+) were mainly observed, while the visible emission lines were rarely observed.

Engineered Protein‐Based Ionic Conductors for Sustainable Energy Storage Applications

Advanced Materials, EarlyView.
Rational incorporation of charged residues into an engineered, self‐assembling protein scaffold yields solid‐state protein films with outstanding ionic conductivity. Salt‐doping further enhances conductivity, an effect amplified in the engineered variants. These properties enable the material integration into an efficient supercapacitor.
