Abstract The electron transport layer (ETL) is a critical component in perovskite quantum dot (PQD) solar cells, significantly impacting their photovoltaic performance and stability. Low-temperature ETL deposition methods are especially desirable for fabricating flexible cells on polymer substrates. Herein, we propose room-temperature-processed tin oxide (SnO 2 ) preparation method PQD cells. process involves synthesizing highly crystalline SnO nanocrystals stabilized with organic ligands, spin-coating dispersion, followed by UV irradiation. energy level of controlled doping gallium ions to reduce the mismatch PQD. proposed ETL-based CsPbI 3 -PQD cell achieves power conversion efficiency ( PCE 12.70%, highest among reported maintaining 94% initial after 500 bending tests. Consequently, demonstrate that systemically designed enhances mechanical stability optoelectronic devices.

Abstract Efficiency, stability, and cost are crucial considerations in the development of photovoltaic technology for commercialization. Perovskite solar cells (PSCs) a promising third‐generation due to their high efficiency low‐cost potential. However, stability organohalide perovskites remains significant challenge. Inorganic perovskites, based on CsPbX ₃ (X = Br − /I ), have garnered attention excellent thermal optoelectronic properties comparable those perovskites. Nevertheless, inorganic faces several hurdles, including need high‐temperature annealing achieve photoactive α‐phase susceptibility transitioning into nonphotoactive δ‐phase under environmental stressors, particularly moisture. These challenges impede creation high‐efficiency, high‐stability devices using low‐cost, scalable manufacturing processes. This review provides comprehensive background fundamental structural, physical, lead‐halide It discusses latest advancements fabricating PSCs at lower temperatures ambient conditions. Furthermore, it highlights progress state‐of‐the‐art devices, manufactured environments reduced temperatures, alongside simultaneous upscaling PSCs.
