Lead Perovskite Semiconductors and their Place in Renewable Energy
Fabian Dauzvardis ’21, Erie, Colorado
Perovskite solid solutions are of greatly increasing technological importance. (CH3NH3)Pb(I1-xBrx)3 perovskites have tunable color properties based on their chemical composition. The size and color is characterized by x-ray diffraction and visible spectroscopy. Their color matches the solar spectrum, and since they are semiconductors, they make a prime candidate as an emerging material for solar cells with higher efficiencies than the classic silicon photovoltaic cell. This talk presents the basics of solid solutions and semiconductors and how it applies to the chemical that was one of the major scientific breakthroughs of 2013 according to both Science and Nature.
