Although they've been around for at least three decades, only in the last few years have metal halide lamps come to be specified routinely in such applications as arena and stadium lighting, parking ...

Metal halide perovskites exhibit a remarkable range of luminescent phenomena arising from their unique crystal structures, tunable bandgaps and excitonic features. In three-dimensional (3D) ...

Waves of light and sound interact to drive electronic and structural changes in a perovskite crystal. At the atomic scale, ...

Common semiconductor materials for solar cells, such as silicon, must be grown via an expensive process to avoid defects within their crystal structure that affect functionality. But metal-halide ...

Researchers have utilized two-dimensional hybrid metal halides in a device that allows directional control of terahertz radiation generated by a spintronic scheme. The device has better signal ...

Researchers have developed hole transport materials such as Spiro-OMeTAD, NiOx, PEDOT:PSS, and PTAA. Common electron transport materials include TiO 2, ZnO, SnO 2, C 60, and PC 61 BM. Applications of ...

(Nanowerk News) University of Missouri scientists are unlocking the secrets of halide perovskites — a material that’s poised to reshape our future by bringing us closer to a new age of ...

Lead-free perovskite solar cells are emerging as lower-toxicity alternatives to lead-based devices, but they still face major ...
