Light trapping polymer-based coatings for cost effective flexible thin film photovoltaics

Thin film silicon solar cells benefit from a lower fabrication cost than crystalline silicon cells, but they have a lower efficiency. The aim of this thesis was to explore the light-management capabilities of sub-micron polymer-based textures, both for the ...

Selective solar absorber coatings on receiver tubes for CSP - energy-efficient production process by sol-gel dip-coating and subsequent induction heating

Jean-Louis Scartezzini, Aïcha Hessler-Wyser, Andreas Schueler, Marina Aymara González Lazo, Martin Joly, Thomas Gascou

The energy efficiency of production processes for components of solar energy systems is an important issue. Other factors, which are important for the production of black selective solar coatings include production speed, cycle time and homogeneity of the ...

Embedded microstructures for daylighting and seasonal thermal control

Nicolas Jolissaint, Jean-Louis Scartezzini, Yves Leterrier, Andreas Schueler, André Gabriel Kostro, Mario Geiger, Marina Aymara González Lazo

A novel concept for an advanced fenestration system was studied and samples were produced to demonstrate the feasibility. The resulting novel glazing will combine the functions of daylighting, glare protection, and seasonal thermal control. Coated microstr ...

UV-nanoimprint lithography and large area roll-to-roll texturization with hyperbranched polymer nanocomposites for light-trapping applications

Jan-Anders Edvin Maansson, Yves Leterrier, Aïcha Hessler-Wyser, Marina Aymara González Lazo, Philippe Couty, Caroline Calderone

Light-trapping textures were produced in hyperbranched polymer (HBP) silica nanocomposites using a UV-nanoimprint lithography (UVNIL) replication method, either in batch or roll-to-roll processes. The hardness of the HBP was found to increase by a factor o ...

A Facile in Situ and UV Printing Process for Bioinspired Self-Cleaning Surfaces

Yves Leterrier, Sara Dalle Vacche, Marina Aymara González Lazo, Feyza Karasu Kiliç, Ioannis Katrantzis

A facile in situ and UV printing process was demonstrated to create self-cleaning synthetic replica of natural petals and leaves. The process relied on the spontaneous migration of a fluorinated acrylate surfactant (PFUA) within a low-shrinkage acrylated h ...

Superhard, Antireflective Texturized Coatings Based on Hyperbranched Polymer Composite Hybrids for Thin-Film Solar Cell Encapsulation

Christophe Ballif, Jan-Anders Edvin Maansson, Yves Leterrier, Franz-Josef Haug, Andreas Schueler, Marina Aymara González Lazo

In this study, we demonstrate by simulation and experiment the antireflective (AR) performance of hyperbranched polymer (HBP) nanocomposites textures replicated from a moth-eye pattern using ultraviolet (UV) nanoimprint lithography. A UV-curable acrylated ...

Novel black selective coating for tubular solar absorbers based on a sol-gel method

Jean-Louis Scartezzini, Andreas Schueler, Marina Aymara González Lazo, Martin Joly, Marina Garcia Gonzalez, Thomas Gascou

Multi layered chrome-free black selective surfaces for solar thermal energy conversion were produced by a low-cost sol gel dip-coating method. The optical properties of the Cu-Co-Mn-Si-O based nanocrystalline thin films have been characterized by spectroph ...

Optical and structural analysis of sol-gel derived Cu-Co-Mn-Si oxides for black selective solar nanocomposite multilayered coatings

Aïcha Hessler-Wyser, Andreas Schueler, Olivia Valérie Charlotte Bouvard, Marina Aymara González Lazo, Martin Joly, Thomas Gascou, Pierre Loesch

In this paper, we report the preparation of the precursor solutions for the deposition of Cu-Co-Mn-Si oxides by a sot-gel method in order to produce black selective coatings for CSP receiver tubes. Their optical properties were investigated by means of spe ...
