Aspects of High Efficiency Perovskite Solar Cells Uncovered With Light 10 Billion Times Brighter Than the Sun TOPICS:Diamond Light SourceGreenEnergyHelmholtz-ZentrumBerlinMaterialsSciencePerovskite Solar CellSolar Cells ByHELMHOLTZ-ZENTRUM BERLIN FÜR MATERIALIEN UND ENERGIENOVEMBER 14, 2019Using crystallographic analyses at the Diamond Light Source (DLS) synchrotron in the United Kingdom, an HZB team has demonstrated that hybrid halide perovskites crystallize without inversion center. Interactions between the organic molecules and adjacent iodine atoms can lead to the formation of ferroelectric domains, which, indirectly, can result in higher solar-cell efficiencies. The formation of these ferroelectric domains cannot occur in purely inorganic perovskites. https://scitechdaily.com/aspects-of-high-efficiency-perovskite-solar-cells-uncovered-with-light-10-billion-times-brighter-than-the-sun/
