A piperidinium salt stabilizes efficient metal-halide ...Traduire cette page

Ionic liquids have been shown to stabilize organic-inorganic perovskite solar cells with metal oxide carrier-transport layers, but they are incompatible with more readily processible organic analogs. Lin et al. found that an ionic solid, a piperidinium salt, enhanced the efficiency of positive-intrinsic-negative layered perovskite solar cells with organic electron and hole extraction layers.

Silicon - Element information, properties and .

Silicon makes up 27.7% of the Earth's crust by mass and is the second most abundant element (oxygen is the first). It does not occur uncombined in nature but occurs chiefly as the oxide (silica) and as silicates. The oxide includes sand, quartz, rock crystal, amethyst, agate, flint and opal. The silicate form includes asbestos, granite, hornblende, feldspar, clay and mica. Elemental silicon ...

01.03.2005 · Similar to the results with Si-nc prepared by pulverizing of porous silicon (Fig. 1B, open circles) clustering of Si-nc made by ball milling is observed when the light scattering experiment is performed.Aggregates with size about 50 nm are detected. Desegregation is achieved when the ammonia is added (30%) (5 drops–1 drop = 0.025 cm 3) to ethanol colloidal solution.

Ball lightning - Wikipedia

Ball lightning is an unexplained atmospheric electrical phenomenon described as luminescent, spherical objects that vary from pea-sized to several meters in diameter.Though usually associated with thunderstorms, the phenomenon is said to last considerably longer than the split-second flash of a lightning bolt. Some nineteenth century reports describe balls that eventually explode and leave ...
