A research team led by Leiping Duan, Cheng Xu, and Jianghui Zheng has published a comprehensive review in Nano-Micro Letters that examines the fundamentals, recent progress, and future prospects of monolithic perovskite/perovskite/silicon triple-junction solar cells (PSTJSCs). With crystalline silicon (c-Si) solar cells approaching their theoretical efficiency limit of 29.4%, multi-junction strategies are regarded as a crucial pathway to further raise power conversion efficiency (PCE). Among them, perovskite-based tandems stand out for their tunable bandgaps, low-cost fabrication, and excellent optoelectronic properties.

Future Outlook
Research on PSTJSCs is shifting from incremental efficiency gains to holistic approaches that integrate bandgap tunability, defect passivation, and stability optimization. Moving forward, emphasis will be placed on developing robust wide-bandgap perovskites with minimized VOC deficits, scalable deposition methods compatible with textured silicon, and encapsulation systems capable of ensuring decades-long stability. By bridging molecular design with device-level architecture, PSTJSCs are positioned to push photovoltaic performance into new frontiers, offering a realistic pathway toward affordable, sustainable, and ultra-efficient solar energy.
