Abstract: Perovskite solar cells （PSCs）, as an emerging photovoltaic technology, have attracted extensive attention from both the academic and industrial communities worldwide due to their excellent photoelectric conversion efficiency, low raw material costs and mild solution processing technology. Since its first report in 2009, the efficiency of the laboratory's certification process has soared from the initial 3.8% to over 27%, demonstrating significant commercial potential. However, during the commercialization process, there are still some problems such as poor long-term stability, difficulties in scalable fabrication, performance degradation in large-area modules and relatively high production costs. From the dual perspectives of international policies and industrial layout, this review systematically examines the policy support and industrial guidance measures adopted by major countries and regions worldwide for the development of perovskite solar cells, along with the current commercialization status and key challenges. It further discusses the current landscape and future trends of leading domestic and international enterprises in terms of technological routes, production capacity deployment, and market strategies. In terms of industrialization challenges, four core issues are analyzed in detail: insufficient long-term stability, poor environmental safety, immature large-scale production processes, and incomplete cost structures and supply chain systems. The current mainstream technologies and corresponding strategies were summarized, such as additive engineering, packaging technology, multi-layer solar cell technology, upgrading of large-scale production processes, artificial intelligence collaboration, and diversified product application expansion. Finally, the future development of perovskite solar technology is envisioned. It was pointed out that perovskite solar technology will advance along the entire value chain through the integration of material innovation, process optimization, and industrial upgrading. Future progress is expected to focus on achieving higher efficiency, enhanced stability, and lower cost, thereby providing essential technological support for the transformation of the global energy structure and the realization of carbon neutrality goals.
