The world record setter broke the record again
Less than a week after the announcement of the new world record of 34.6% crystalline silicon-perovskite tandem cell at the SNEC exhibition in Shanghai, LONGi has made a new breakthrough in the efficiency of crystalline silicon-perovskite tandem cells.
On June 19, local time, LONGi announced that the commercial M6 crystalline silicon-perovskite tandem cell developed by the LONGi tandem team achieved a photoelectric conversion efficiency of 30.1%, which is 28.6% higher than that of the previous technical route, after being independently certified by the Fraunhofer Institute for Solar Cell Research (Fraunhofer ISE), an authoritative certification body in the field of solar cells The record increased by 1.5 percentage points, marking a breakthrough in the commercial application of crystalline silicon-perovskite tandem cell technology.
While continuing to explore the efficiency limit of tandem cells, the LONGi R&D team began to simultaneously carry out research on the mass production technology of tandem cells for commercial applications in October 2023, and in just six months, they successively overcame the two key problems of large-area perovskite film preparation and ultra-low temperature metallization in the air, and combined with the research process experience of prototype devices, for the first time, achieved a photoelectric conversion efficiency of more than 30% on commercial-size crystalline silicon-perovskite tandem cell devices.
Crystalline silicon-perovskite tandem cells have a theoretical ultimate efficiency of up to 43%, which is considered to be the next generation of ultra-efficient solar cells after monocrystalline silicon back-contact cells (BC), and is an emerging photovoltaic technology that is being studied by the global photovoltaic industry. LONGi's breakthroughs in prototype devices and wafer-level tandem cells not only redefine the efficiency limit of tandem cells at both ends, but also take a key step towards the industrialization of tandem cells, helping LONGi continue to lead in the two mainstream tracks of crystalline silicon single-junction cells and tandem cells. At present, LONGi is the "double champion" of the two world records of cell efficiency in crystalline silicon single-junction cells (27.30%) and crystalline silicon-perovskite tandem cells (34.6%).
The creation of this world record once again proves that every technological breakthrough of LONGi is not based on the data advancement of the laboratory, but is guided by industrialization and centered on customer needs, forming an efficient R&D system and sufficient technical reserves of "mass production generation, development generation, research generation and exploration generation", and quickly introducing advanced cutting-edge technologies from around the world into mass production, so as to promote the technological upgrading of the whole industry.
BC full-scene products have attracted much attention
In the context of the rapid iteration of global photovoltaic technology and the diversification of customer needs, LONGi relies on its innovative BC cell technology route and a series of high-performance products to meet the customized needs of customers through differentiated innovation.
At this exhibition, LONGi brought BC full-scenario products to the show, including not only BC products in distributed and centralized scenarios, but also functional scenario products and solutions such as anti-dust accumulation, damp heat resistance, LONGDING 4.0, "green electricity" + "green hydrogen". This is the European premiere of LONGi's BC all-scenario products.
At present, LONGi Green Energy is constantly improving the BC product matrix and continuing to build differentiated competitiveness.
For example, on May 7, LONGi released a new generation of ultra-high-value module Hi-MO 9 in Madrid, Spain, based on high-efficiency HPBC 2.0 cell technology, integrating a variety of advanced technologies, with core advantages such as higher power generation capacity, lower BOS cost and higher reliability, with a maximum power of 660W and a conversion efficiency of up to 24.43%.
The Hi-MO 9 module was launched and received a strong response from the market. "The company's orders in hand are close to 1GW, and the customer order backlog has exceeded 5GW." "The company originally planned to supply about 10GW of Hi-MO 9 products globally in 2025, but according to the positive signals released by the current market, it is necessary to increase production capacity to meet the rapidly growing market demand," She said. "This market feedback not only proves the great potential and value of BC technology, but also lays a solid foundation for LONGi's future development.
"Don't lead, don't expand." This is the principle that LONGi has always adhered to. With the maturity of new technologies, LONGi's BC expansion pace is also accelerating. According to reports, in the next three years, LONGi's annual monocrystalline silicon wafer production capacity is expected to reach 200 GW, of which Terry's silicon wafer production capacity accounts for more than 80%, BC cell annual production capacity will reach 100 GW, and monocrystalline module annual production capacity will reach 150 GW. The Hi-MO 9 is expected to reach mass production in the fourth quarter of this year.
Three certificates have been issued in a row to ensure the safety and reliability of hydrogen energy
On June 20, DEKRA, the world's leading third-party inspection and certification organization, issued the DEKRA AOC (Assessment of Compliance) certificate and the DEKRA carbon footprint verification certificate to LONGi hydrogen energy water electrolysis hydrogen production system and alkaline electrolyzer respectively. This is not only a strong proof of the safety, reliability, efficiency and economy of LONGi's hydrogen production equipment and systems, but also a full affirmation of LONGi's continuous implementation of carbon reduction and energy transition.
The DEKRA K196 standard AOC certificate is based on strict evaluation criteria, and comprehensively certifies the safety, stability, DC power consumption and other key performance indicators of the 1000 standard cubic meters/hour water electrolysis hydrogen production system that has been continuously operated and commercialized, and two certificates are issued, proving that the equipment indicators of LONGi hydrogen energy water electrolysis hydrogen production system meet the standards, and the performance is safe, reliable, efficient, economical and trustworthy.
According to the ISO14067 and PAS2050 standards, DEKRA verification results show that the carbon emissions of LONGi's ALK Hi1-1000 standard cubic meters per hour series alkaline water electrolysis hydrogen production products from the cradle to the gate are 305.88kgCO₂/(Nm³/h), which is far lower than the limit of 800kgCO₂/(Nm³/h) of the hydrogen energy leader action.
Zhang Haimeng, Vice President of LONGi Green Energy, said at the ceremony that LONGi Hydrogen Energy is committed to becoming the world's leading large-scale green hydrogen equipment manufacturer and solution provider, and helping to achieve the global carbon neutrality goal through "green electricity" + "green hydrogen" solutions. It is a great honor that LONGi Hydrogen Energy has obtained two AOC certificates for the performance of alkaline water electrolysis hydrogen production equipment and the world's first alkaline electrolyzer carbon footprint verification certificate issued by DEKRA. The three certificates are not only a high recognition of the quality of LONGi's hydrogen energy products, but also a full affirmation of LONGi's continuous practice of carbon reduction and energy transformation.
As a leading large-scale green hydrogen equipment manufacturer and solution provider in the industry, LONGi Hydrogen Energy has achieved the "three firsts" of No. 1 domestic market share, No. 1 in the world in terms of alkaline electrolyzer production capacity, and No. 1 gas production per tank in 2023. In the future, LONGi Hydrogen Energy will continue to increase R&D investment, continuously improve product performance and market competitiveness, expand application scenarios, and contribute more to the global energy transition.
