Self-assembled 1D/3D heterojunction enables all-inorganic perovskite 4-terminal tandem solar cells with 21.54% certified efficiency
) after operating for 1210 hours at 65 °C and 650 hours at 85 °C (ISOS-L-2). When it is combined with a narrow-band all-inorganic PSC in the 4-T tandem configuration, a certified efficiency of 21.54% was obtained, which is the highest reported for this type of tandem cells. Through synergistic optimization of interface stabilization and tandem optoelectronic management, this work provides valuable insights for developing efficient and stable all-inorganic perovskite tandem solar cells.
