Investigation and review of mirrors reflectance in parabolic trough solar collectors (PTSCs)

open access: yesEnergy Reports, 2019
As mirrors used in concentrating solar systems influence the thermal efficiency of the systems collectors to a large extent, the reflectance of mirrors plays a critical role in the thermal efficiency of parabolic trough solar collectors.

Solar reflectance of ETICS finishing coatings – a comparison of experimental techniques [PDF]

open access: yesE3S Web of Conferences, 2020
The solar reflectance has a significant role in the thermal behaviour and surface temperature of ETICS finishing coats. Incomplete information of solar reflectance of ETICS with nanopigments can sometimes difficult their adequate selection. In this work,

Efficiency Enhancement of GaAs Single-Junction Solar Cell by Nanotextured Window Layer

open access: yesApplied Sciences, 2022
In order to improve efficiency of flexible III-V semiconductor multi-junction solar cells, it is important to enhance the current density for efficiency improvement and to attain an even efficiency of solar cells on a curved surface.

The Use of Hemispherical Directional Reflectance to Evaluate the Interaction of Food Products with Radiation in the Solar Spectrum

open access: yesFoods, 2022
Food product packaging should block light to protect nutrients, color and active ingredients in functional food from degradation. Currently, packages are not optimized in terms of the solar radiation impact on the products they contain.

Investigations on the Influence of Surface Textures on Optical Reflectance of Multi-crystalline Silicone (MC-Si) Crystal Surfaces-Simulations and Experiments

open access: yesInternational Journal of Renewable Energy Development, 2022
MC-Si is the most widely used material for making solar PV cells. In spite of the considerable research on improving the conversion efficiency of MC-Si solar PV cells still it remains well within the range of 15-20%.

Individual reflectance of solar radiation confers a thermoregulatory benefit to dimorphic males bees (Centris pallida) using distinct microclimates.

open access: yesPLoS ONE, 2023
Incoming solar radiation (wavelengths 290-2500 nm) significantly affects an organism's thermal balance via radiative heat gain. Species adapted to different environments can differ in solar reflectance profiles.

Enhanced spectral splitting in a novel solar spectrum optical splitter based on one dimensional photonic crystal heterostructure

open access: yesJournal of Materiomics, 2021
Controlling the distribution of solar spectrum in different bands would boost the energy harvesting efficiency and optimize the energy dispatchability. 1D photonic crystal with intrinsic optical band gap can be used to split the solar spectrum for hybrid
