N2 - Perovskite solar cells (PSCs) have experienced a rapid increase in power conversion efficiency (PCE) over the past decade, positioning them as strong candidates for next-generation commercial photovoltaics (PVs). Their tunable bandgap makes them ideal for tandem configurations, especially when coupled with crystalline silicon (Si) bottom cells; this combination offers the potential to exceed the PCE limits of single-junction devices and is arguably essential for successful market entry of perovskite technologies. However, commercialization of perovskite/Si tandems also demands enhanced durability and reliable integration into PV modules, withstanding long-term outdoor exposure. Besides light, temperature, and voltage bias stress, difficulties to overcome involve the mechanical stability and performance of the interfaces within tandem devices, which may degrade over time under real-world operating conditions. This review explores the critical role of interface engineering in addressing these challenges, reviewing the latest advancements in interface materials, encapsulation strategies, and novel integration techniques. By identification of the critical issues and adequate solutions, this paper provides a vision for the future of perovskite/Si tandem solar cells, emphasizing the importance of advanced manufacturing techniques and interdisciplinary research but also policy support.
