The company single-handedly developed a <strong>two-terminal crystalline silicon-perovskite tandem solar cell<\/strong>, which accomplished its latest milestone and once again broke its world record for crystalline silicon-perovskite tandem cell efficiency. LONGi&#8217;s solar cell achieved a conversion efficiency of 34.85%, and it was certified by the US National Renewable Energy Laboratory (NREL).<\/p>\n<p>Crystalline silicon-perovskite tandem solar cells pave the way for next-generation ultra-efficient solar cells and boast a theoretical efficiency limit of 43%, far surpassing the Shockley-Queisser (SQ) limit for single-junction solar cells (33.7%).\u00a0LONGi\u2019s tandem solar cell R&amp;D team has consistently pushed the boundaries of this technology:<\/p>\n<ul>\n<li>November 2023: The R&amp;D team achieved a tandem solar cell efficiency of 33.9%, nearing the SQ limit.<\/li>\n<li>June 2024: The R&amp;D team made a new record with 34.6% conversion efficiency.<\/li>\n<li>Latest Milestone: Within a year, the R&amp;D team achieved a new world record of 34.85% efficiency, showcasing the formidable R&amp;D capabilities and relentless innovation drive of the LONGi Central Research Institute.<\/li>\n<\/ul>\n<h2>LONGi is breaking the laws of energy<\/h2>\n<p>The Chinese photovoltaic module manufacturer announced its proprietary hybrid interdigitated back contact (HIBC) crystalline silicon solar cell, which is based on a full-size silicon wafer, achieved a <strong>world record power conversion efficiency of 27.81%<\/strong>. The result was certified by Germany\u2019s Institute for Solar Energy Research Hamelin (ISFH).<\/p>\n<p>The cell also achieved a short-circuit current of 5,698 mA, an open-circuit voltage of 744.9 mV, and a fill factor of 87.55%. The performance beats the company&#8217;s old record of 27.3%, which was achieved in May 2024. Since that breakthrough, the company has come a long way since its early years. Its world records in both single-junction crystalline silicon solar cells and crystalline silicon-perovskite tandem solar cells ensure that the company remains the \u201cDual Champion\u201d in solar innovation and reinforces its leadership in <a href=\"https:\/\/www.ecoportal.net\/en\/sheet-makes-any-surface-photovoltaic\/6651\/\">core photovoltaic technologies<\/a>.<\/p>\n<blockquote><p>\u201cBy redesigning both the cell architecture and material systems, we achieved simultaneous breakthroughs in optical management and carrier transport efficiency,\u201d the spokesperson stated, without providing further details.This opens a new frontier for enhancing module power density and sets a benchmark for the next generation of photovoltaic performance.\u201d &#8211; LONGi spokesperson<\/p><\/blockquote>\n<h2>It is more than just a typical solar panel<\/h2>\n<p>LONGi highlights independent innovation and technological R&amp;D, consistently progressing cost reduction and efficiency enhancement across the industry through the industrialization of pioneering technologies. These approaches established a significantly efficient R&amp;D system and technology reserves, underlined by the strategy of &#8220;<strong>mass production for one generation, R&amp;D for the next, and technology reserves for the future<\/strong>.&#8221; LONGi remains committed to technological innovation, leveraging self-developed breakthroughs and unique technologies to promote the global energy transition.<\/p>\n<blockquote>\n<p style=\"text-align: left;\">&#8220;In the solar industry, conversion efficiency is a defining metric. Each one-point increase in cell efficiency translates into more than a 5% reduction in system costs.&#8221; &#8211; Li Zhenguo, founder and president of LONGi Green Energy<\/p>\n<\/blockquote>\n<p>So, this is a solar panel, but it&#8217;s also not. Its record-breaking efficiency places this technology in a whole other category, making it <strong>so much more than the typical solar panel<\/strong>. Not only does it decrease system costs and provide efficient energy, but it also significantly <a href=\"https:\/\/www.ecoportal.net\/en\/carpeting-mountains-with-solar-panels\/7658\/\">contributes to China&#8217;s attempt to decrease global carbon emissions<\/a>, making this super solar panel eco-friendly. We believe this isn&#8217;t the last we&#8217;ve heard of LONGi, and we cannot wait to see more of their record-breaking technology.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Solar energy is a clean, abundant, and increasingly affordable source of power.\u00a0It&#8217;s a renewable resource, meaning it doesn&#8217;t deplete the Earth&#8217;s resources.\u00a0Solar panels can be used anywhere, including space, and are becoming more efficient and cost-effective.
