On November 19, 2025, Wu Sai Technology made an exciting announcement: it had successfully completed the first mass delivery of its "light conversion film for perovskite tandem modules." The product has already been shipped to a well - known photovoltaic enterprise in the United States. This event represents a groundbreaking moment, as it marks the world's inaugural commercial application of this technology within the perovskite module industry. It has effectively cleared a major obstacle that has been hindering the large - scale development of perovskite technology.

Perovskite materials are highly sensitive to both humidity and oxygen. The long - term stability of these materials has long been a bottleneck preventing their widespread industrialization. Wu Sai Technology's light conversion film operates through a sophisticated light conversion mechanism. It can transform ultraviolet light into visible light. By doing so, it reduces the material degradation caused by ultraviolet rays. This, in turn, enhances the module's ability to withstand harsh weather conditions and extends its lifespan. Moreover, it increases the amount of effective light input, leading to an approximate 5% boost in photoelectric conversion efficiency.

Wu Sai Technology has now established itself as the sole legitimate supplier in this particular field. Looking ahead, the company plans to expand its market reach and collaborate with more leading perovskite manufacturers in the future.
