Lead (Pb) halide perovskites have witnessed highly promising achievements for high-efficiency solar cells, light-emitting diodes (LEDs), and photo/radiation detectors due to their exceptional optoelectronic properties. However, compound stability and Pb toxicity are still two main obstacles towards the ...
can be obtained from multiple sources around the world. No such standardization is yet to occur for metal halide lamps. Furthermore, not enough is known or published about the spectral stability of these lamps at different irradiance levels. Does the spectrum shift at high irradiance versus low?
Metal halide perovskite has emerged as a promising material for light-emitting diodes. In the past, the performance of devices has been improved mainly by optimizing the active and charge injection layers. However, the large refractive index difference among different materials limits the overall light...

Solution-processed metal-halide perovskites are emerging as one of the most promising materials for displays, lighting and energy generation. Currently, the best-performing perovskite optoelectronic devices are based on lead halides and the lead toxicity
While there has been significant transfer of knowledge from the metal oxide community to the field of metal halide perovskites, the halides bring their own set of peculiarities and complexities. The lower formal oxidation states of the constituent ions, e.g., Cs(I)Pb(II)I3 versus Ca(II)Ti(...
Group 4 complexes of the form (η5-C5R5)M(L)X2 (M = Group 4 metal, L = supporting ligand, X = halide or alkyl), which are supported by one cyclopentadienyl and one κ1-bound formally monoanionic ligand, have been well studied [9, 11, 46]. The monoanionic ligands act as an is...
Solar electricity is an unlimited source of sustainable fuels, yet the efficiency of solar cells is limited. The efficiency of perovskite solar cells improved from 3.9% to reach 25.5% in just a few years. Perovskite solar cells are actually viewed as promising by comparison with dye-sensitized ...
Metal halide perovskites can be readily synthesized, they exhibit tunable physical properties and excellent performance, and they are heavily studied optoelectronic materials. Compared to the typical three-dimensional perovskites, morphological-level one
Lead-halide perovskites have triggered the latest breakthrough in photovoltaic technology. Despite the great promise shown by these materials, their instability towards water even in the presence of low amounts of moisture makes them, a priori, unsuitabl
