A Three-Dimensional Quantum Dot Network Stabilizes Perovskite Solids via Hydrostatic Strain

Lattice-mismatched perovskite quantum dots embedded in a perovskite matrix generate homogeneous hydrostatic compressive strain as confirmed by GIWAXS, improving the operational stability of 1.77 eV wide-bandgap solar cells to >90% PCE retention after 200 h of one-sun MPP tracking.
