Multifunctional Photochromic Piezoionic Eutectogels Through Interfacial Nanoparticle Engineering

Advanced Functional Materials, EarlyView.
Photochromic WO3 nanoparticles enable photoresponsive piezoionics in deep eutectic solvent‐based eutectogels by coupling photoinduced electronic processes with pressure‐driven ionic transport. Interfacial nanoparticle engineering enhances ionic mobility and electromechanical output, while reversible photoactivation modulates the electrical response ...

Theoretical and Experimental Study of Spectral Selectivity Surface for Both Solar Heating and Radiative Cooling

International Journal of Photoenergy, 2015
A spectral selectivity surface for both solar heating and radiative cooling was proposed. It has a high spectral absorptivity (emissivity) in the solar radiation band and atmospheric window band (i.e., 0.2~3 μm and 8~13 μm), as well as a low absorptivity

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

Advanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Estimating solar radiation according to semi empirical approach of Perrin de Brichambaut: application on several areas with different climate in Algeria

International Journal of Energetica, 2016
The solar energy reaching a given surface is directly dependent on the orientation thereof and the position of the sun. To get maximum energy from the sun, it is necessary a good solar receiver orientation towards the solar radiation where the solar ...
