Abstract
Abstract Developing high‐quality wide bandgap (WBG) perovskites with ≈1.7 eV bandgap ( E g ) is critical to couple with silicon and create efficient silicon/perovskite tandem devices. The sufferings of large open‐circuit voltage ( V OC ) loss and unstable power output under operation continuously highlight the criticality to fully develop high‐quality WBG perovskite films. In this study, rubidium and thiocyanate as additive regulators in WBG perovskites are incorporated, significantly reducing non‐radiative recombination, ion‐migration, and phase segregation. The optimized 1.66 eV E g perovskite solar cells achieved state‐of‐art 1.3 V V OC (0.36 V deficit), and delivered a stabilized power conversion…
