Meeting future energy demands with sustainable sources like photovoltaics (PV) presents significant land and logistical challenges, which can be mitigated by improving PV power conversion efficiency (PCE) decentralized solutions building-integrated solar-integrated mobility systems (e.g., Unmanned Aerial Vehicles (UAVs)). Metal Halide Perovskites Solar Cells (MH-PSCs) provide a transformative, low-cost solution for high-efficiency diverse compositions, exceptional optoelectronic properties, low-temperature, solution-based processability. Conventionally the MH-PSCs are fabricated in "p-i-n" or "n-i-p" configuration on glass-Transparent Conductive Oxide (TCO) substrates. While glass-based Perovskite (PSCs) have achieved remarkable efficiencies, their limited scalability, high areal-weight, mechanical rigidity greatly limit usage wearables electronics, BIPVs, e-mobility applications. Addressing these challenges requires "targeted architectural innovations" MH-PSCs, tailored to specific applications, drive practical deployment forward. This study reviews four innovative PSC architectures-Interdigitated Back Contact (IBC) PSCs, Lateral Configuration (LC) Fiber-Shaped (FS) Substrate-Configuration (SC) PSCs-highlighting design advancements enhanced efficiency, flexibility, lightweight, application-specific integration. Importantly, review discusses precise engineering required each layer of innovations ensure compatibility, efficient charge transport, durability, scalability while optimizing performance, also identifying key outlining directions R&D.
