Phase Evolution Kinetics in Additive‐Free 19.75% Organic Photovoltaics Empowered by Solvent Vapor Annealing

Advanced Functional Materials, EarlyView.
Solvent vapor annealing enables kinetic control of additive‐free morphology in organic solar cells. Selective plasticization of acceptor forms an optimal fibrillar network, boosting efficiency to 19.06% (binary) and 19.75% (ternary), with ultrafast exciton dissociation and reduced recombination.

Solar maculopathy secondary to sunlight exposure reflected from the screen of mobile devices: two case reports

Journal of Medical Case Reports, 2022
Background Solar maculopathy is a well described clinical entity that usually occurs in patients that have gazed directly the sun. In this report we describe the first two cases of solar maculopathy in individuals exposed to sunlight reflected from the ...

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

Advanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...

Experimental Study of the Effect of Reflection Mirrors Orientation on the Performance of Solar Still

Journal of Engineering and Sustainable Development, 2012
The present experimental work is a study of solar still with reflected mirrors. The solar radiation was calculated mathematically for angles ranging from 9o to 30o with 15o increment for reflected mirrors and from 0-45o with 5o increment for glass cover.

Synergistic Cu‐Fe Interactions Enhance Phase Transformation Kinetics Toward High‐Performance CuFeS2‐Based All‐Solid‐State Batteries

Advanced Functional Materials, EarlyView.
CuFeS2 is found to induce the formation of intermediate phases, highlighting a strong Cu–Fe synergistic effect during conversion reactions in lithium all‐solid‐state batteries (Li‐SSBs). The integrated reaction pathway effectively suppresses phase separation and accelerates reaction kinetics, leading to enhanced electrochemical reversibility and ...
