Perovskite solar cells (PSCs) have emerged at the forefront of contemporary photovoltaic research as one of the most promising next-generation technologies, owing to their potential to deliver high power conversion efficiencies (PCEs) at comparatively low manufacturing costs. Over the past decade, this class of solar energy materials has demonstrated a remarkable advancement, both in terms of material innovation and device engineering. Notably, within a relatively short span, laboratory-scale PSC prototypes have achieved certified efficiencies surpassing 27%, positioning them in direct competition with long-established photovoltaic materials such as crystalline silicon, GaAs and cadmium telluride (CdTe). This progress has been driven by intensive global research efforts aimed at optimizing compositional engineering, interfacial modification, and deposition methodologies. Nevertheless, despite the widespread academic interest in this field, the reproducibility of high-efficiency PSCs remains a significant bottleneck. Only a limited number of research laboratories worldwide have demonstrated the consistent fabrication of devices exceeding the 20% efficiency threshold under standard testing conditions.
Present work addresses the challenges of standardization and procedural transparency by delineating detailed fabrication protocols for PSCs based on the regular n−i−p structure. Our objective is to furnish a comprehensive, methodologically rigorous account of each stage in the device preparation process, encompassing material selection, substrate treatment, layer deposition, annealing regimes, and characterization techniques. Establishing improved reporting standards and shared fabrication practices may serve as a catalyst for accelerating both the technological maturation of perovskite photovoltaics and the broader expansion of their application in sustainable energy systems.
