ABSTRACT The rapid improvement in the power conversion efficiency of perovskite solar cells has established them as a promising alternative to conventional photovoltaic technologies. Owing to their strong light absorption, tunable bandgap, solution processability, and lightweight nature, perovskite solar cells are particularly well suited for building‐integrated photovoltaic applications. This review summarizes the potential of perovskite solar cells for building‐integrated photovoltaic integration, with a focus on their implementation in semi‐transparent windows, colored facades, and flexible substrates. By enabling on‐site energy generation while preserving aesthetic and design flexibility, perovskite photovoltaics offer unique opportunities for urban energy systems. Finally, future research directions are outlined, focusing on materials and interface engineering, encapsulation strategies, and large‐area fabrication, which are essential for the practical deployment of perovskite solar cell–based building‐integrated photovoltaics in sustainable buildings.
