AB  - Perovskite/silicon tandem solar cells are promising to penetrate photovoltaicmarket. However, the wide-bandgap perovskite absorbers used in top-celloften suffer severe phase segregation under illumination, which restricts theoperation lifetime of tandem solar cells. Here, a strain modulation strategyto fabricate light-stable perovskite/silicon tandem solar cells is reported. Byemploying adenosine triphosphate, the residual tensile strain in the wide-bandgapperovskite absorber is successfully converted to compressive strain,which mitigates light-induced ion migration and phase segregation. Basedon the wide-bandgap perovskite with compressive strain, single-junctionsolar cells with the n–i–p layout yield a power conversion efficiency (PCE) of20.53% with the smallest voltage deficits of 440 mV. These cells also maintain83.60% of initial PCE after 2500 h operation at the maximum power point.Finally, these top cells are integrated with silicon bottom cells in a monolithictandem device, which achieves a PCE of 26.95% and improved light stabilityat open-circuit.
