Study of Si doped VO2 thin films for solar thermal applications

Andreas Schueler, Anna Krammer, Olivia Valérie Charlotte Bouvard

A new generation of smart solar thermal collectors is based on thermochromic thin film technology. Thermochromic absorber coatings change their optical properties with temperature, particularly in the infrared range. In order to prevent overheating, the co ...

Efficient electron transfer and reduced recombination with Nd:YAG laser scribing for high-efficiency quantum dot-sensitized solar cells

Minkyu Son

Inefficient charge transfer and charge recombination are critical but challenging issues that restrict the power conversion efficiency (PCE) of quantum-dot-sensitized solar cells (QDSSCs). These issues must be addressed to boost the performance of QDSSCs. ...

Polystyrene CuO/Cu2O uniform films inducing MB-degradation under sunlight

César Pulgarin, Juan Kiwi, Sami Rtimi, Oualid Baghriche

This study reports on a Cu-sputtered film on polystyrene (PS) leading to the discoloration/degradation of methylene blue (MB) under low intensity solar simulated irradiation. Direct current magnetron sputtering (DCMS) was used to graft uniform, adhesive Cu ...

Electron Stability and Negative-Tetron Luminescence in Free-Standing Colloidal n-Type CdSe/CdS Quantum Dots

Arianna Marchioro

We examine the effects of CdS shell growth on photochemical reduction of colloidal CdSe quantum dots (QDs) and describe the spectroscopic properties of the resulting n-type CdSe/CdS QDs. CdS shell growth greatly slows electron trapping. Because of this imp ...

Elevated transition temperature in Ge doped VO2 thin films

Mihai Adrian Ionescu, Arnaud Magrez, Andreas Schueler, Anna Krammer, Wolfgang Amadeus Vitale, Piotr Mocny

Thermochromic GexV1-xO2+y thin films have been deposited on Si (100) substrates by means of reactive magnetron sputtering. The films were then characterized by Rutherford backscattering spectrometry (RBS), four-point probe electrical resistivity measuremen ...
