Thermochromic solar absorber coatings with elevated transition temperature

Due to their simple design and operation, solar thermal collectors for domestic hot water gener-ation and space heating are one of the most common solar energy harvesting systems in use today. Dur-ing cold periods all the absorbed energy is useful. During ...

Practical challenges in the development of photoelectrochemical solar fuels production

Sophia Haussener, Miguel Antonio Modestino

This article addresses the challenges presented by photoelectrochemical solar fuels technology in a discussion that begins with a functioning device and proceeds to the more fundamental science of its component parts. In this flow of discussion issues are ...

Criteria and policies to master the visual impact of solar systems in urban environments: The LESO-QSV method

Christian Roecker, Maria Cristina Munari Probst

Increased use of solar collectors in buildings is necessary but poses major challenges in existing built environ ments, especially where architectural quality is an issue. The large size of solar systems at the building scale requires careful planning, as ...

Infrared Optical Properties of Doped and Pure Thermochromic Coatings for Solar Thermal Absorbers

Anna Krammer, Josef Andreas Schuler, Fabrice Thierry Demière

A new generation of solar collectors is based on thermochromic thin film technology, where the remarkable optical changes of vanadium dioxide, through its reversible semiconductor-to-metal phase transition, are exploited. This study reports on the infrared ...

Thermochromic coatings for overheating protection of solar thermal collectors - novel type of doping (TARGET95)

Andreas Schueler, Anna Krammer

Overheating and the resulting stagnation of solar thermal collectors is a common problem even in central European latitudes. During stagnation, high temperatures lead to water evaporation, glycol degradation and stresses in the collector with increasing va ...

Comparison-Based Optical Assessment of Hyperboloid and Ellipsoid Reflectors in a Beam-Down Solar Tower System With Linear Fresnel Heliostats

Meng Lin

Beam-down concentrating solar tower (BCST) is known for its merits in easy installation and maintenance as well as lower convection heat loss of the central receiver (CR) when comparing to a traditional concentrated solar tower system. A point-line-couplin ...

Hybrid Heterojunctions of Solution-Processed Semiconducting 2D Transition Metal Dichalcogenides

Kevin Sivula, Nestor Guijarro Carratala, Xavier Adrian Jeanbourquin, Natalie Renuka Banerji, Xiaoyun Yu, Muhammad Aiman Bin Rahmanudin Hamdan

Exfoliated transition metal dichalcogenides (2D-TMDs) are attractive light-harvesting materials for large-area and inexpensive solar energy conversion given their ability to form highly tolerant heterojunctions. However, the preparation of large-area heter ...

Thermal solar collector with VO2 absorber coating and V1-xWxO2 thermochromic glazing – Temperature matching and triggering

Andreas Schueler, Rosendo Sanjines, Antonio Paone, Mario Geiger

Overheating is a common problem both with the use of active and passive solar energy in thermal solar energy systems and in highly glazed buildings, even in central European latitudes. In solar thermal collectors, the elevated temperatures occurring during ...
