Effect of light scattering on the performance of a direct absorption solar collector

Kwang Hyun WON, Bong Jae LEE

Frontiers in Energy 2018, Volume 12, Issue 1,   Pages 169-177 doi: 10.1007/s11708-018-0527-5

Abstract: The collector efficiency of a direct absorption solar collector (DASC) is very sensitive to optical propertiesof the working fluid, such as absorption and scattering coefficients.could be comparable to their absorption cross-section depending on the particle size, especially whenIn the analysis, the Monte Carlo method is employed to numerically solve the radiative transfer equationof nanofluid is carefully engineered depending on its value of the absorption coefficient.

Nanostructured gold films exhibiting almost complete absorption of light at visible wavelengths

Hanbin Zheng, Christine Picard, Serge Ravaine

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 2,   Pages 247-251 doi: 10.1007/s11705-018-1710-2

Abstract: Nanostructured metal surfaces have been known to exhibit properties that deviate from that of the bulk material. By simply modifying the texture of a metal surface, various unique optical properties can be observed. In this paper, we present a simple two step electrochemical process combining electrodeposition and anodization to generate black gold surfaces. This process is simple, versatile and up-scalable for the production of large surfaces. The black gold films have remarkable optical behavior as they absorb more than 93% of incident light over the entire visible spectrum and also exhibit no specular reflectance. A careful analysis by scanning electron microscopy reveals that these unique optical properties are due to their randomly rough surface, as they consist in a forest of dendritic microstructures with a nanoscale roughness. This new type of black films can be fabricated to a large variety of substrates, turning them to super absorbers with potential applications in photovoltaic solar cells or highly sensitive detectors and so on.
