Scientists Improve Stability and Efficiency of Solar Cells

Perovskites are a relatively new class of semiconductors used in optoelectronics, which are considered to be an efficient alternative to the silicone that is traditionally used in solar cells. To solve the main issue — instability — the scientists turned to methylammonium lead iodide (MAPbI₃).

30 Shades of Steel: Scientists Develop ’Cheat Sheet’ for the Creation of New Steels

Researchers from the National University of Science and Technology “MISIS” developed a database that will help create new grades of steels. This will to speed up the process of creating innovative steel grades with specified strength and ductility allow at least 10 times, which will allow manufacturing car bodies of the most complex shapes. Article on the research is published in “Calphad”.

Ancient Lead Can Help Experimental Physics

Scientists from the National University of Science and Technology MISIS measured the number of trace impurities in the ingots of ancient lead from the sunken ship of the ancient Romans, using a novel technology. It was shown that lead, which stayed underwater for 1500 years, contains such a small amount of radioactive elements — Uranium and Thorim, that it can be used without any purification in one of the most “demanding” areas — Nuclear physics — in the study of elementary particles. The experiment on the selection and determination of micro-impurities was carried out in cooperation with colleagues from the Joint Institute for Nuclear Research and the National Center for Scientific Research (France). An article about the development published in the journal Talanta.

Scientists Increase Stability and Efficiency of Perovskite Solar Cells

Scientists from NUST MISIS and IPCE RAS (Moscow, Russia) together with Italian colleagues from University of Rome Tor Vergata managed to significantly increase stability and effectiveness of perovskite elements — promising materials for solar energy — by adding a layer of copper iodide (CuI). The article on the research is published in “Materials”.
