Researchers uncover the chemical interactions that make perovskites unstable
A team of researchers from Brookhaven National Lab, Georgia Institute of Technology, Argonne National Laboratory, Istituto CNR di Scienze e Tecnologie Chimiche “Giulio Natta” (CNR-SCITEC) and Helmholtz-Zentrum Berlin für Materialien und Energie has examined the mechanism that causes degradation of formamidinium-based halide perovskites and have been able to stop it using a thin layer of molecules that repels water.
“Perovskites have the potential of not only transforming how we produce solar energy, but also how we make semiconductors for other types of applications like LEDs or phototransistors. We can think about them for applications in quantum information technology, such as light emission for quantum communication,” said Juan-Pablo Correa-Baena, assistant professor in the School of Materials Science and Engineering and the study’s senior author. “These materials have impressive properties that are very promising.”
