Core achievements
【summary】
Mechanism: Increasing the lattice perturbation of perovskite can inhibit the migration of perovskite halogen ions and light-induced phase separation.
Materials: Based on this mechanism, a light-stable 2.0eV Rb/Cs all-inorganic perovskite material was developed.
Device: The all-inorganic perovskite material is used in the top cell of the three-junction photovoltaic, so that the perovskite-based three-junction photovoltaic efficiency is improved from the original 20% to 24%, and the ...
