The interface strain increases with the degree of lattice mismatch (Fig. These approaches have resulted in increased charge separation efficiency, but reduced manufacturing convenience and repeatability due to lattice mismatch, especially for large-area films. Similarly, PEC, as a new promising energy technology 10, 11, is developing some hierarchical composites to address these issues, such as core-shell heterojunction 12 and layered heterojunction 13. Obviously, selecting a semiconductor to meet some requirements, such as higher carrier mobility, appropriate band structure and interface state, is the key for this kind of BHJ with the perovskite. A bulk heterojunction (BHJ) strategy with a high efficiency for charge separation and ultrafast charge transfer increases the power conversion efficiency of solar cells 6, 7, 8, which also enables cathodic energy efficiency in CO 2 electroreduction 9. Charge recombination is a major limit in thin films to achieve high-efficiency devices, including inorganic perovskite solar cells, organic solar cells, and photoelectrochemical (PEC) tandem cells, seriously restricting their service life 1, 2, 3, 4, 5.
