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，在德国慕尼黑举行的2024年欧洲太阳能光电展上，全球领先的太阳能技术公司隆基绿能技术股份有限公司（以下简称“隆基”）于2024年6月19日正式公布了商业M6尺寸硅钙钛双联太阳电池片30.1%的新世界纪录效率。
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%.
德国Fraunhofer太阳能能源研究所的权威认证机构独立验证，该商业M6尺寸硅钙钛双层太阳能电池的光伏转换效率达到了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%.
自上周隆基在上海2024年SNEC EXPO上宣布新的34.6%双层太阳能电池效率新世界纪录以来，不到一周时间，它又打破了2023年5月M4商业硅片上28.6%双层太阳能电池效率的先前世界记录，具有1.5%的绝对效率优势。
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.
隆基中央研发中心研发总监何波博士在发布会上表示，隆基取得的新世界纪录效率不仅在推动硅钙钛双层电池原型的效率极限方面取得了重大进展，而且也标志着这项技术商业化的一个里程碑，这标志着隆基团队在发展中取得了突破。
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.
何波博士说：“在不断探索双层太阳能电池效率极限的同时，隆基的研发团队于2023年10月开始研究该技术的大规模生产技术，并在短短六个月内克服了两个关键挑战：空气中大面积钙钛矿膜的制备和超低温金属化。”结合原型器件研究的经验，研发团队首次在商业级硅钙钛双孔电池器件上实现了超过30%的光伏转换效率，这显示出其在隆基最近创造的27.3%的效率记录上显着占优势，极大地提升了全球光伏行业对硅钙钛双孔太阳能电池技术的信心和预期。
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.
单晶硅钙钛双孔太阳能电池的理论限制效率高达43%，这使它们成为继单晶硅背接触（BC）电池之后下一代超高效太阳能电池。它们是一种新兴的光伏技术，受到全球光伏行业积极研究。
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.
同时创造这一双层太阳电池的“双冠王”世界纪录不仅重新定义了两端双层电池的效率限制，也迈出了对双层太阳电池的工业化的一步，帮助隆基继续在单晶硅单结太阳电池和双层太阳电池两个主流领域引领。
"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.
