Researchers at the University of Toledo (UToledo) in the United States claim to have fabricated the most air-stable two-dimensional/three-dimensional (2D/3D) tin (Sn) perovskite solar cell to date as part of a research project aimed at identifying lead (Pb)-free perovskite materials for PV applications. In 2D/3D perovskite solar cells, a 2D perovskite phase is combined with a conventional 3D perovskite absorber, typically at an interface or in a mixed-dimensional structure. The 2D layer can passivate defects, improve charge-carrier transport and extraction, and suppress ion migration. Cells incorporating ...Den vollständigen Artikel lesen ...
