Abstract Perovskite/silicon tandem solar cells demonstrating tremendous potential for commercialization that position them as a transformative technology in photovoltaics. However, the poor interface contact between perovskite and C 60 has long been critical factor limiting power conversion efficiency (PCE) of top cells. Here, multifunctional inorganic tantalum oxide (TaO X) film passivation layer is introduced, which not only suppresses recombination across but also improves energy level alignment enhances charge extraction at perovskite/C interface. More importantly, TaO X demonstrates exceptional thermal stability, significantly overall stability device.

Abstract Tandem solar cells (TSCs) based on wide bandgap (WBG) perovskites have gained significant attention for their higher power conversion efficiency (PCE) compared to single‐junction cells. The role of WBG perovskite (PSCs) as the sub‐cell in tandem consists absorbing high‐energy photons and producing open‐circuit voltages ( V OC ). However, PSCs face serious phase separation issues, resulting poor long‐term stability substantial loss TSCs. In response, researchers developed a range strategies mitigate these challenges, showing promising progress, comprehensive review is expected. this review, we discuss mechanism organic–inorganic hybrids all‐inorganic perovskites. Additionally, conduct an in‐depth investigation various enhance stability, including component engineering, additive interface dimension control, solvent encapsulation. Furthermore, application TSCs summarized detail. Finally, perspectives are provided offer guidance development efficient stable field
