Persistent enhancement of exciton diffusivity in CsPbBr3 nanocrystal solids
In semiconductors, exciton or charge carrier diffusivity is typically described as an inherent material property. Here, we show that the transport of excitons among CsPbBr3 perovskite nanocrystals (NCs) depends markedly on how recently those NCs were occup ...
Amer Assoc Advancement Science2024Alleviating nanostructural phase impurities enhances the optoelectronic properties, device performance and stability of cesium-formamidinium metal-halide perovskites
Christophe Ballif, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Christian Michael Wolff, Daniel Anthony Jacobs, Austin George Kuba, Mostafa Rabie Shlaly Bahr Othman, Beat Ruhstaller, Anaël Morgane Jaffrès
The technique of alloying FA+ with Cs+ is often used to promote structural stabilization of the desirable alpha-FAPbI3 phase in halide perovskite devices. However, the precise mechanisms by which these alloying approaches improve the optoelectronic quality ...
Royal Soc Chemistry2024Thermal sensing device and sensory feedback system and method using such thermal sensing device
Silvestro Micera, Solaiman Shokur, Outman Akouissi, Jonathan Louis Muheim, Francesco Iberite
The present invention concerns a thermal sensing device (1) and a sensory feedback system and method using such thermal sensing device, comprising at least one film (19) of electrically insulating polymer defining a global surface of the thermal sensing de ...
2024Homogenous power distribution along gyrotron collector walls
Stefano Alberti, Jean-Philippe Hogge, Damien Fasel, Ugo Siravo, Jérémie Dubray, Miguel Filipe Silva Füglister, Pierre-François Isoz
EC RF power sources will play a major role in the future operation of large scale tokamaks (ITER, DEMO). A 1MW/170GHz gyrotron is the standard RF power unit considered for ITER. Even though the efficiency of such devices has been significantly increased th ...
2023On the dependence of Water Use Efficiency on aridity.
Water use efficiency (WUE) describes how efficiently plants transpire water to assimilate carbon and produce biomass. Here, we used a variety of data sources, including leaf-level gas exchange measurements, tree-ring isotopes, flux-tower observations, and ...
2023Tuning the Solar Performance of Building Facades through Polymer 3D Printing: Toward Bespoke Thermo-Optical Properties
Stephen William Wasilewski, Arno Schlueter
Facades are the primary interface controlling the flow of solar energy in buildings and affecting their energy balance and environmental impact. Recently, large-scale 3D printing (3DP) of translucent polymers has been explored as a technique for fabricatin ...
WILEY2023Electrostatic particle collector
Satoshi Takahama, Nikunj Dudani
ESP particle collector (1) for collecting particles in a particle containing gas stream, comprising an inlet section (4), a collector section (6), and an electrode arrangement (8), the inlet section comprising a flow tube (10) defining a gas flow channel ( ...
2023Molecular Tailoring of Pyridine Core-Based Hole Selective Layer for Lead Free Double Perovskite Solar Cells Fabrication
Mohammad Khaja Nazeeruddin, Peng Huang
To solve the toxicity issues related to lead-based halide perovskitesolar cells, the lead-free double halide perovskite Cs2AgBiBr6 is proposed. However, reduced rate of charge transferin double perovskites affects optoelectronic performance. We designeda s ...
AMER CHEMICAL SOC2023Assessment of the technological viability of photoelectrochemical devices for oxygen and fuel production on Moon and Mars
Sophia Haussener, Byron Stuart Ross
Human deep space exploration is presented with multiple challenges, such as the reliable, efficient and sustainable operation of life support systems. The production and recycling of oxygen, carbon dioxide (CO2) and fuels are hereby key, as a resource resu ...
2023Beam radiation penetration in particle b e ds for heat transfer modeling of a centrifugal solar particle receiver
Evan Fair Johnson, Serdar Hiçdurmaz
This article describes a study of beam radiation striking particle beds of randomly packed, spherical par-ticles. The current study is focused on concentrating solar power receivers which use solid particles as a heat transfer medium, but results are appli ...
