Recently, the news of a major breakthrough in the field of photovoltaics came that Trina Solar, a national key laboratory, announced an achievement that shocked the industry. The laboratory's 800 large-size perovskite/crystalline silicon tandem cell modules have been officially certified after rigorous testing by TÜV SÜD. The peak power of this device is as high as 0W, which successfully breaks the 0W mark and sets a new power record for the world's industrial standard size photovoltaic module products.

According to the detailed introduction, as the efficiency improvement of crystalline silicon cells is gradually approaching the limit, the industry has begun to focus on tandem cell technology, especially perovskite tandem technology. This technology can break through the physical limit efficiency of single-junction cells, and theoretically increase the efficiency to 43%. Therefore, perovskite/crystalline silicon tandem technology is regarded as the vane of the next generation of photovoltaic technology, heralding a historic shift from "silicon-based cells" to "tandem cells".

天合光能在鈣鈦礦疊層技術領域的佈局始於2014年，公司與南京大學、南開大學、華北電力大學以及中科院長春應化所等多所知名高校合作，共同承擔了江蘇省的科技支撐專案。2019年，天合光能更是參與了國家重點專案“鈣鈦礦/晶體矽兩端疊層太陽電池的設計、製備和機理研究”。在這一領域，天合光能已經累計申請了331件專利，通過鈣鈦礦體相摻雜、介面處理以及複合層結構的設計等多種創新手段，不斷提升鈣鈦礦/晶體矽疊層電池的轉換效率。

This achievement not only marks Trina Solar's profound accumulation and outstanding strength in the field of photovoltaic technology, but also injects new vitality and hope into the development of the global photovoltaic industry. With the continuous maturity and application of perovskite tandem technology, we have reason to believe that the photovoltaic industry will usher in more efficient, environmentally friendly and sustainable development in the future.
