Optical and morphological characterisation of low refractive index materials for coatings on solar collector glazing

Jean-Louis Scartezzini, Andreas Schueler, Estelle De Chambrier, Marie Schaer, Martin Joly, Stefan Mertin, Virginie Hody-Le Caër

Nanostructured coatings based on the elements Si, O, Mg, and F have been deposited as thin films by solegel dip-coating in a particle-free atmosphere. The refractive index of the prepared SiO2 and quaternary MgeFeSieO thin films has been determined from sp ...

Facade Integration of Solar Thermal Collectors: A Breakthrough?

Christian Roecker, Jean-Louis Scartezzini, Andreas Schueler, Estelle De Chambrier, Maria Cristina Munari Probst

One main barrier to the acceptability of façade use of solar thermal collectors is their black appearance and the visibility of piping or absorber irregularities through the glazing. To facilitate façade integration, a project was set up to develop selecti ...

Quantum dot containing nanocomposite thin films for phtoluminescent solar concentrators

Martin Python, Andreas Schueler, Estelle De Chambrier

Silicon oxide films containing CdS quantum dots have been deposited on glass substrates by a sol–gel dip-coating process. Hereby the CdS nanocrystals are grown during the thermal annealing step following the dip-coating procedure. Total hemispherical trans ...

Sol-gel deposition and characterization of low refractive index nanocomposite Mg:F:Si:O thin films for solar and protective coatings

Christian Roecker, Jean-Louis Scartezzini, Estelle De Chambrier, Josef Andreas Schuler, Dipanwita Dutta

Coatings for thermal solar energy conversion have to be abrasion-resistant, stable at elevated temperatures, and often have to protect the substrate against corrosion. Due to the conditions of refractive index matching between the substrate and the ambient ...

Sol-gel deposition and optical characterization of multilayered SiO2/Ti1-xSixO2 coatings on solar collector glasses

Christian Roecker, Jean-Louis Scartezzini, Andreas Schueler, Estelle De Chambrier

Thin films of silicon oxide and silicon titanium mixed oxides are deposited on solar collector glazing in a sol–gel dip-coating process based on alcoxide precursors. Spectrophotometry is used to characterize the relation of film thickness and withdrawal sp ...

Sol-gel deposition of nanostructured low refractive index materials on solar collector glazing

Christian Roecker, Jean-Louis Scartezzini, Estelle De Chambrier, Josef Andreas Schuler, Dipanwita Dutta

Nanoporous SiO2 and nanocomposite MgF2:SiO2 coatings have been deposited by sol gel dip-coating in a particle-free atmosphere. The refractive index of the prepared nanostructured thin films is determined from spectrophotometric data. In both cases, signifi ...

Thin film multilayer design types for colored glazed thermal solar collectors

Christian Roecker, Jean-Louis Scartezzini, Andreas Schueler, Estelle De Chambrier

Multilayered inteference filters of dielectric thin films have been designed for the application as energy-efficient coloration of collector cover glasses. The optical behavior of the designed multilayers is analyzed by computer simulations yielding the CI ...

Angle-dependent spectrophotometry of Sol-Gel deposited multilayered oxide coatings on solar collector glasses

Christian Roecker, Jean-Louis Scartezzini, Andreas Schueler, Estelle De Chambrier, Dipanwita Dutta

Multilayered thin oxide films have been deposited on solar collector glazing by sol-gel dip coating in a dust-free environment provided by a laminar flux chapel. A superior film quality and a satisfying film homogeneity have been achieved for the produced ...
