General description

Lead(II)iodide is a wide bandgap (2.32 eV) semiconductor material. It has uniqueproperties like high resistivity, chemical stability, and a wide range oftemperature applications (−200 °C up to +130 °C). Perovskites with lead as the central cation produce the bestphotovoltaic efficiency. We offer lead iodide, specifically designed forenhanced solar cell performance.

Application

Lead iodide finds application in synthesis of perovskites based photovoltaic materials. Our perovskite grade PbI2 can readily be dissolved in DMF to yield 1M solution.
Lead(II) iodide (PbI2) in perovskite grade refers to high-purity lead iodide specifically used for the synthesis and fabrication of perovskite materials, such as formamidinium lead iodide (FAPbI3) or methylammonium lead iodide(MAPbI3), which are commonly studied for perovskite solar cells and other optoelectronic devices. The high purity of lead(II) iodide perovskite grade contributes to the efficiency, stability and reproducibility of perovskite solar cells.

Other Notes

Very air and moisture sensitive. Please handle under argon atmosphere in a glove box.

Metal-halide perovskites are crystalline materials originally developed out of scientific curiosity. Unexpectedly, solar cells incorporating these perovskites are rapidly emerging as serious contenders to rival the leading photovoltaic technologies. Power conversion efficiencies have jumped from 3% to over 20% in

Articles

To achieve net-zero emissions by 2050, renewable power contributions must triple. Photovoltaic stations provide vital utility power, achieved primarily through third- and fourth-generation technology. Promising trends include recycling and revolutionary, ultra-lightweight, flexible, and printable solar cells.

Dr. Perini and Professor Correa-Baena discuss the latest research and effort to obtain higher performance and stability of perovskite materials.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
