A new spectrally selective coating based on carbon nanotubes (CNTs) for solar thermal applications is demonstrated. For optimized coatings solar absorptance coefficients alpha > 0.92 and thermal emittance coefficients epsilon < 0.1 (400 degrees C) were achieved. These results render CNT coatings as a low cost and high performance alternative to commercially available vacuum deposited cermet coatings for concentrated solar power (CSP) application.

The role of polysulfide-saturation in electrolytes for high power applications of real world Li-S pouch cells

Tom Boenke, Sebastian Kirchhoff, Florian S. Reuter, Florian Schmidt, Christine Weller, Susanne Dorfler, Kai Schwedtmann, Paul Hartel, Thomas Abendroth, Holger Althues, Jan J. Weigand, Stefan Kaskel

Summary: Lithium-sulfur (Li-S) batteries have high theoretical specific energy and are promising for lightweight applications like aviation and heavy electric vehicles. However, their rate capability needs improvement. This study evaluates a combination of sparingly polysulfide solvating electrolyte and highly conductive carbon nanotube Buckypaper (CNT-BP) and finds that the sparingly polysulfide solvating electrolyte has better rate capability. This evaluation is an important step towards customizing Li-S batteries for practical applications.

Mechanistic Insights into the Cycling Behavior of Sulfur Dry-Film Cathodes

Magdalena Fiedler, Sahin Cangaz, Felix Hippauf, Susanne Doerfler, Thomas Abendroth, Holger Althues, Stefan Kaskel

Summary: All-solid-state lithium-sulfur batteries (ASSB-LiS batteries) are advanced candidates for future energy storage systems due to their enhanced safety and higher energy densities. A solvent-free process to prepare free-standing cathode sheets with low binder content has been demonstrated in this study. The sheet-type cathodes achieve nearly theoretical sulfur utilization and outstanding capacity retention, and an all-solid-state pouch cell using the dry-film cathode shows good performance at different C-rates.

On the role of history-dependent adsorbate distribution and metastable states in switchable mesoporous metal-organic frameworks

Francesco Walenszus, Volodymyr Bon, Jack D. Evans, Simon Krause, Juergen Getzschmann, Stefan Kaskel, Muslim Dvoyashkin

Summary: A unique feature of metal-organic frameworks (MOFs) is their structural switchability, which offers a wide range of functionality for sustainable energy applications. This study provides experimental evidence for fluid metastability and history-dependent states during sorption in MOFs, leading to the counterintuitive phenomenon of negative gas adsorption (NGA). The authors used various techniques to examine n-butane molecular dynamics and the framework response during the sorption process, revealing the role of metastable states in the NGA transitions.

Florian S. Hoffmann, Florian Schmidt, Jannes Mueller, Kay Schoenherr, Susanne Doerfler, Thomas Abendroth, Holger Althues, Arno Kwade, Nae-Lih Wu, Stefan Kaskel

Summary: In this study, a new low density electrolyte based on hexyl methyl ether (HME) and 1,3-dioxalane (DOL) was introduced, which allows the use of graphite as anode material for Li-S batteries. By using symmetric graphite vs. graphite cells, an average Coulombic efficiency of 99.94% per electrode could be achieved. Furthermore, the cycling conditions for Li-S cells with graphite anodes were optimized for the first time, and the feasibility of the concept was demonstrated in multilayer pouch cells under realistic conditions.

Defining specifications for accurate Metal/TCO specific contact resistivity measurements by TLM in silicon heterojunction devices

Senami Zogbo, Wilfried Favre, Olivier Bonino, Marie-Estelle Gueunier-Farret

Summary: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

Ribbons lengthening induced by thermal cycling in PV modules part I: Cell-ribbon mechanical interaction through the solder

Jean-Baptiste Charpentier, Philippe Voarino, Julien Gaume

Summary: The phenomenon of ribbon lengthening in PV modules exposed to thermal cycling is not well explained in the literature. In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.

Optical absorption driven by efficient refraction and light concentration for photovoltaic applications

Ankit Kumar, Ankit Chauhan, Jordi Llobet, Helder Fonseca, Patricia C. Sousa, Carlos Calaza, Gil Shalev

Summary: This study found that decorating subwavelength arrays with SiO2 quasi-nanolenses (qNL arrays) can enhance the absorption of the solar spectrum. Optical absorption mechanisms in qNL arrays were investigated using near-field scanning optical microscopy (NSOM), revealing that the enhancement is a result of the combination of effective antireflection coating, increased optical interactions between adjacent dielectrics for elevated light trapping, and strong light concentration due to the presence of qNLs.
