c-Si PV cells emissivity characterization at low operating temperatures for efficiency management [PDF]

MATEC Web of Conferences, 2020
Efficiency is a critical parameter for a solar cell to be successful and is closely related to the working temperature of the cell. In turn, the temperature can be related to the infrared emissivity, the parameter that governs the thermal radiative ...

Preparation and Angle-Dependent Optical Properties of Brown Al/MnO2 Composite Pigments in Visible and Infrared Region

Nanoscale Research Letters, 2017
Traditional low infrared emissivity coatings based on aluminum flakes cannot own low IR emissivity and low lightness simultaneously. Herein, a new simple efficient method for the synthesis of brown Al/MnO2 composite pigments with low IR emissivity and ...

Coupling of Epsilon-Near-Zero Mode to Mushroom-Type Metamaterial for Optimizing Infrared Suppression and Radiative Cooling

Photonic Sensors, 2022
We report a complementary metal oxide semiconductor (CMOS) compatible metamaterial-based spectrally selective absorber/emitter (MBSSAE) for infrared (IR) stealth, which has the low absorption/emissivity in the IR atmospheric transmission window (3 µm–5 ...

Emissivity retrievals with FORUM's end-to-end simulator: challenges and recommendations [PDF]

Atmospheric Measurement Techniques, 2022
Spectral emissivity is a key property of the Earth's surface, of which only very few measurements exist so far in the far-infrared (FIR) spectral region, even though recent work has shown that the FIR is important for accurate modelling of the global ...

Observing the variation of asteroid thermal inertia with heliocentric distance [PDF]

, 2018
Thermal inertia is a useful property to characterise a planetary surface since it can be used as a qualitative measure of the regolith grain size. It is expected to vary with heliocentric distance because of its dependence on temperature.

Design, Preparation and Characterization of Mid-infrared Low-emissivity Film

Journal of Physics: Conference Series, 2023
Abstract The rapid development of infrared detection technology requires that military targets have mid-infrared stealth performance. In this paper, a mid-infrared low-emissivity film based on one-dimensional photonic crystal structure was designed and prepared.

A Broadband Study of Galactic Dust Emission [PDF]

, 2006
We have combined infrared data with HI, H2 and HII surveys in order to spatially decompose the observed dust emission into components associated with different phases of the gas. An inversion technique is applied.

Actively tunable rasorber with broadband RCS reduction and low infrared emissivity

Optics Express, 2023
In this paper, an actively tunable rasorber with broadband RCS reduction and low infrared emissivity is proposed. The rasorber can achieve flexible control of the peak of the transmission frequency and make the platform invisible in multiple spectrum.
