The investigation of degradation seven distinct sets (with a number individual cells n ≥ 12) state the art organic photovoltaic devices prepared by leading research laboratories with combination imaging methods is reported. All have been shipped to and degraded at Risø DTU up 1830 hours in accordance established ISOS-3 protocols under defined illumination conditions. Imaging device function different stages was performed laser-beam induced current (LBIC) scanning; luminescence imaging,...
Seven distinct sets (n ≥ 12) of state the art organic photovoltaic devices were prepared by leading research laboratories in a collaboration planned at Third International Summit on Organic Photovoltaic Stability (ISOS-3). All shipped to RISØ DTU and characterized simultaneously up 1830 h accordance with established ISOS-3 protocols under three illumination conditions: accelerated full sun simulation; low level indoor fluorescent lighting; dark storage daily measurement simulation. Three...
Abstract Zinc‐ion batteries (ZIBs) are emerged as a promising alternative for sustainable energy storage, offering advantages such safety, low cost, and environmental friendliness. However, conventional aqueous electrolytes in ZIBs face significant challenges, including hydrogen evolution reaction (HER) zinc dendrite formation, compromising their cycling stability safety. These limitations necessitate innovative electrolyte solutions to enhance ZIB performance while maintaining...
This work is part of the inter-laboratory collaboration to study stability seven distinct sets state-of-the-art organic photovoltaic (OPV) devices prepared by leading research laboratories. All have been shipped and degraded at RISØ-DTU up 1830 hours in accordance with established ISOS-3 protocols under defined illumination conditions. In this work, we apply Incident Photon-to-Electron Conversion Efficiency (IPCE) situ IPCE techniques determine relation between solar cell performance...
The present work is the fourth (and final) contribution to an inter-laboratory collaboration that was planned at 3rd International Summit on Organic Photovoltaic Stability (ISOS-3). involved six laboratories capable of producing seven distinct sets OPV devices were degraded under well-defined conditions in accordance with ISOS-3 protocols. degradation experiments lasted up 1830 hours and more than 300 cells 100 devices. analyzed characterized different points their lifetimes by a large...
Reactions involving MI2 where M=Mg, Ca, Sr, Ba or Zn and M'TpC* M'=Na Tl TpC*=tris[3-methoxy-1,1-dimethyl)pyrazolyl]hydroborate in tetrahydrofuran are described leading to the isolation characterization of complexes TpC*MgI, , TpC*CaI, TpC*SrI, TpC*SrI(THF), TpC*BaI, TpC*BaI(pz*H), pz*H=3-(2-methoxyl-1,1-dimethyl)pyrazole, TpC*BaI.1/2toluene, TpC*ZnI, . The compounds have been characterized by single-crystal X-ray crystallography. Compounds isostructural salt-like containing kappa6-TpM+...
The synthesis of 3-(2-methoxy-1,1-dimethylethyl)pyrazole, pz*H is described together with its reactions the borohydrides MBH(4), where M = Li, Na, and K, under melt conditions. At 180 degrees C, this procedure leads to a mixture products for at higher temperatures, derivative LiTp'pz*H, 1, isolated, wherein B-H bond methyl group have been eliminated B-O has formed. For reaction proceeds give tris-pyrazolylborate NaTp*, 2, but temperatures tetra-pyrazolylborate complex NaB(pz*)(4), 3,...
A tris-pyrazolylborate ligand bearing ether appendages is shown to be a potential hemilabile based on NMR studies and structural characterization of its eta3, eta5, eta6, micro-binding modes in coordination with Li+, Na+, K+, Tl+, Ca2+ ions.
The preparation, structures and solution NMR properties of the title compounds are reported and, remarkably, (TpC*)2M, where M = Ca Mg, exist as salts in solid state undergo facile TpC* ligand exchange solution.
