LONGi Announces the New World Record Efficiency of 30.1% for the Commercial M6 Size Wafer-level Silicon-perovskite Tandem Solar Cells
MUNICH, June 21, 2024 /PRNewswire/ -- The world-leading solar technology company, LONGi Green Energy Technology Co., Ltd. (hereafter as "LONGi"), officially announced the new world record efficiency of 30.1% for the commercial M6 size wafer-level silicon-perovskite tandem solar cell on June 19, 2024 at the 2024 Intersolar Europe in Munich, Germany.
2024年6月21日，在德國慕尼黑舉行的2024年歐洲太陽能光電展上，全球領先的太陽能技術公司隆基綠能技術股份有限公司（以下簡稱“隆基”）於2024年6月19日正式公佈了商業M6尺寸硅鈣鈦雙聯太陽電池片30.1%的新世界紀錄效率。
The commercial M6 size wafer-level silicon-perovskite tandem solar cell independently certified by the authoritative certification institutions of the Fraunhofer Institute for Solar Energy (Fraunhofer ISE) in Germany achieved photovoltaic conversion efficiencies of 30.1%.
德國Fraunhofer太陽能能源研究所的權威認證機構獨立驗證，該商業M6尺寸硅鈣鈦雙層太陽能電池的光伏轉換效率達到了30.1%。
The release of this new world record comes less than a week after LONGi announced a new world record of 34.6% tandem solar cell efficiency at the 2024 SNEC EXPO in Shanghai, and it also breaks the previous world record of 28.6% wafer-level tandem solar cell efficiency on M4 commercial size wafers in May 2023 with an absolute efficiency advantage of 1.5%.
自上週隆基在上海2024年SNEC EXPO上宣佈新的34.6%雙層太陽能電池效率新世界紀錄以來，不到一週時間，它又打破了2023年5月M4商業硅片上28.6%雙層太陽能電池效率的先前世界記錄，具有1.5%的絕對效率優勢。
Dr. He Bo, R&D Director of LONGi Central R&D Institute, spoke at the launch ceremony that the new world record efficiencies achieved by LONGi represent not only a significant advancement in pushing the efficiency limits of silicon-perovskite tandem cell prototypes but also a milestone in the commercial viability of this technology, marking a breakthrough by LONGi's team in its development.
隆基中央研發中心研發總監何波博士在發佈會上表示，隆基取得的新世界紀錄效率不僅在推動硅鈣鈦雙層電池原型的效率極限方面取得了重大進展，而且也標誌着這項技術商業化的一個里程碑，這標誌着隆基團隊在發展中取得了突破。
Dr. He Bo said: "While continuously exploring the efficiency limits of tandem solar cells, LONGi's R&D team started research on mass production technology for tandem solar cells in October 2023, and in just six months, they overcame two key challenges: the preparation of large-area perovskite films in air and ultra-low-temperature metallization." Combining the experience in prototype device researches, the R&D team achieved a photovoltaic conversion efficiency of over 30% for the first time on commercial-sized silicon-perovskite tandem solar cell devices, showing a significant efficiency advantage over LONGi's recently created efficiency record of 27.3%, greatly boosting the global photovoltaic industry's confidence and expectations for silicon-perovskite tandem solar cell technology.
何波博士說：“在不斷探索雙層太陽能電池效率極限的同時，隆基的研發團隊於2023年10月開始研究該技術的大規模生產技術，並在短短六個月內克服了兩個關鍵挑戰：空氣中大面積鈣鈦礦膜的製備和超低溫金屬化。”結合原型器件研究的經驗，研發團隊首次在商業級硅鈣鈦雙孔電池器件上實現了超過30%的光伏轉換效率，這顯示出其在隆基最近創造的27.3%的效率記錄上顯着佔優勢，極大地提升了全球光伏行業對硅鈣鈦雙孔太陽能電池技術的信心和預期。
The theoretical limit efficiency of monocrystalline silicon-perovskite tandem solar cells is up to 43%, making them the next generation of ultra-high efficiency solar cells after monocrystalline silicon back-contact (BC) cells. They are an emerging photovoltaic technology that is being actively researched by the global photovoltaic industry.
單晶硅鈣鈦雙孔太陽能電池的理論限制效率高達43%，這使它們成爲繼單晶硅背接觸（BC）電池之後下一代超高效太陽能電池。它們是一種新興的光伏技術，受到全球光伏行業積極研究。
The creation of this "Dual-Champion" world records for tandem solar cells not only redefines the efficiency limit of two-terminal tandem cells but also takes a key step towards the industrialization of tandem solar cells, helping LONGi to continue leading in both the mainstream tracks of monocrystalline silicon single-junction solar cells and tandem solar cells.
同時創造這一雙層太陽電池的“雙冠王”世界紀錄不僅重新定義了兩端雙層電池的效率限制，也邁出了對雙層太陽電池的工業化的一步，幫助隆基繼續在單晶硅單結太陽電池和雙層太陽電池兩個主流領域引領。
"LONGi's Central R&D Institute, the backbone of the company, boasts a vibrant research team exceeding 5000 members. Notably, the team dedicated to advancing crystal silicon-perovskite tandem solar cells technology, which has consistently shattered global efficiency records, has a remarkably youthful average age of just 28 years." Dennis She, Vice President of LONGi, introduced the strong team at the workshop "Technological innovation and intelligent manufacturing help the photovoltaic industry move towards new prosperity". LONGi has attached great importance to research and innovation in technology since its establishment. Since its listing in 2012 until the end of 2023, LONGi has invested over 30 billion yuan in R&D, and has obtained a total of 2879 authorized patents.
