Reverse-bias resilience of monolithic perovskite/silicon tandem solar cellsXu et al.JouleSeptember 5, 2023In BriefWe experimentally demonstrate that monolithic perovskite/silicon tandem solar cells possess a superior reverse-bias resilience compared with perovskite single-junction solar cells. The majority of the reverse-bias voltage is dropped across the more robust silicon subcell, protecting the perovskite subcell from reverse-bias-induced degradation. These results highlight the advantages of monolithic perovskite/silicon tandems in withstanding partial shading-induced reverse-bias stress and indicate a higher commercial readiness level of the tandems compared with their perovskite single-junction counterparts.
