What is CH3NH3PbI3?
Methylammonium lead iodide (CH3NH3PbI3) perovskite solar cell has produced a remarkable breakthrough in the photovoltaic history of solar cell technology because of its outstanding device based performance as a light-harvesting semiconductor.
What is lead II iodide used for?
The applications of lead iodide are in printing, bronzing, mosaic gold and photography. It is also used as a detector for high-energy photons such as X- rays and gamma rays.
Why is lead II iodide yellow?
This experiment starts with two soluble ionic compounds: potassium iodide, and lead (II) nitrate. It also produces a rapid colour change, as the lead iodide is very insoluble in water at room temperature. When the solutions are added together, they immediately produce a bright yellow precipitate of lead iodide.
Does PbO contain lead II?
… lead compounds are the oxides: lead monoxide, PbO, in which lead is in the +2 state; lead dioxide, PbO2, in which lead is in the +4 state; and trilead tetroxide, Pb3O4.
What is perovskite material?
A perovskite is a material that has the same crystal structure as the mineral calcium titanium oxide, the first-discovered perovskite crystal. Generally, perovskite compounds have a chemical formula ABX3, where ‘A’ and ‘B’ represent cations and X is an anion that bonds to both.
How do you handle lead iodide?
7. The precipitate (lead iodide) must be disposed of by a licensed hazardous waste disposal company according to Flinn Suggested Disposal Method #27f. A Beral pipet may be used as a substitute for a metal scoop. Using scissors remove half the bulb and use the remaining portion of the bulb as a scoop.
What is the symbol of lead iodide?
PbI2
Lead(II) iodide/Formula
What are the uses of methylammonium lead halide?
They have potential applications in solar cells, lasers, light-emitting diodes, photodetectors, radiation detectors, scintillator, magneto-optical data storage and hydrogen production. In the CH 3 NH 3 PbX 3 cubic crystal structure the methylammonium cation (CH 3 NH 3+) is surrounded by PbX 6 octahedra.
What is the crystal structure of methylammonium lead?
CH 3 NH 3 PbX 3 crystal structure. Methylammonium lead halides (MALHs) are solid compounds with perovskite structure and a chemical formula of CH 3 NH 3 PbX 3, where X = I, Br or Cl.
How much is a discount on ethylammonium iodide?
Spend over £8,000.00 for an 8% discount or spend over £10,000.00 for a 10% discount. Ethylammonium iodide (EAI), like methylammonium iodide, is a precursor used for high-efficiency pervoskite solar cells and LEDs.
