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.

Self-assembled monolayers (SAMs) deposited on the hole-collecting electrodes of p-i-n perovskite solar cells effectively replace bulky hole transporting layers. However, mechanism by which control electronic processes and how they depend properties monolayer molecules remain poorly understood. In this study, we developed a simplified cell imitator with blocked electron extraction to investigate photocurrent dynamics between ITO electrode. We investigated photoluminescence photovoltage under short laser pulse excitation addressed influence monomolecular transport Our findings reveal that is significantly affected layers, in turn methods sample preparation exploration. Photocurrent determined several processes, including charge carrier displacement local electric field, ITO, trapping holes interface trap states, electron-hole recombination at interface. propose model takes into account molecular dipole moments their ionization potentials partially explain different influences interfacial rates.

Perovskite solar cells (PVSCs) show remarkable potential due to their high-power conversion efficiencies and scalability. However, challenges related stability long-term performance remain significant. Self-assembled monolayers (SAMs) have emerged as a crucial solution, enhancing interfacial properties, facilitating hole extraction, minimizing non-radiative recombination. This review examines recent advancements in SAMs for PVSCs, focusing on three key areas: anchoring groups interface engineering, electronic structure modulation well band alignment, optimization. We emphasize the role of reducing defects improving crystallinity, alongside ability fine-tune energy levels more effective extraction. Additionally, co-adsorbed SAM strategies was discussed which can enhance durability PVSCs against thermal moisture degradation. Overall, present promising avenue addressing both efficiency paving way toward commercial viability. Future research should prioritize environmental scaling up applications industrial implementation.
