Trinasolar's n-type i-TOPCon cell achieves 25.9% efficiency
Vertically integrated PV manufacturer Trinasolar's National Key Laboratory of Photovoltaic Science and Technology has announced that its high-efficiency n-type i-TOPCon cell has achieved a maximum efficiency of 25.9%. Calling it a ‘new world record, Trina says this achievement is certified by the testing laboratory of ISFH. The company says it ‘has set or broken a world record’ for the 27th time. The cell uses a 210 × 182 mm² large-area monocrystalline silicon wafer, which is phosphorus-doped through the Czochralski (CZ) process. It integrates advanced technologies such as quantum tunneling passivated contact, low recombination emitter, double-sided optical trapping design, and advanced metallization. These innovations significantly enhance the optical and electrical performance of the cell, setting a new benchmark for the industrial production of large-area n-type monocrystalline TOPCon cells.
Recently, another major solar manufacturer LONGi published a research paper, reporting how it achieved over 27% cell efficiency for its BC cells (see China Solar PV News Snippets).
Risen Energy Launches Hyper-ion Pro HJT Module
Solar panel manufacturer Risen Energy has introduced its latest heterojunction (HJT) module, named Hyper-ion Pro, which it says is now ready for mass production and shipment. Currently rated for a power output of 720 W, Risen plans to increase it further to 730 W+ in Q1 2025, achieving a module efficiency of 23.5%. The company says the module has a bifaciality of 85% and integrates light-converting materials and optimized encapsulation processes, reducing UV light transmittance to 2% under UV60 irradiation in its first year. It uses screen printing technology to enhance wear resistance, which Risen says extends its lifespan by 2-3 times, while high-mobility target technology boosts power output and cell-to-module (CTM) efficiency. Risen claims Hyper-ion Pro is expected to improve power generation per watt by 2.6% compared to TOPCon modules, while increasing the internal rate of return (IRR) by 3.17% and reducing levelized cost of energy (LCOE) by 2.94%.
Risen recently announced that its HJT Hyper-ion modules have successfully passed the IEC extreme low-temperature load test (see China Solar PV News Snippets).
TCL TZE supplies shingled modules for 16 GW Kubuqi Desert Base
Manufacturer of wafers to modules TCL TZE has announced that it has begun supplying solar modules for the new energy base jointly developed by China Three Gorges Corporation and Inner Mongolia Energy Group in the Kubuqi Desert, located in the north-central Ordos region. The Kubuqi Desert will host what is claimed to be the world's largest wind and solar power base, with a total installed capacity of 16 GW. TCL TZE will provide 200 MW of modules for the project, with the first batch of 50 MW n-type G12R-68P shingled modules delivered in mid-October. According to TCL TZE, these modules are designed to endure harsh desert conditions with a front load capacity of 5,400 Pa, allowing them to withstand high-speed sand impact and abrasion. The modules use high-reliability encapsulation materials to resist intense UV radiation in the desert, effectively preventing material aging. Additionally, the company says their power temperature coefficient has been improved to -0.29%/°C, making them more efficient in high-temperature operating conditions.
LONGi and TCL TZE announced price increases for their wafer products in late August (see China Solar PV News Snippets).
Sungrow's ‘Rubik's Cube’ platform for new energy power plants
Solar inverter manufacturer Sungrow’s new energy development and investment arm Sungrow New Energy has unveiled a new technology platform called ‘Rubik's Cube’ for renewable energy power plants. It says the platform is built around 3 core technologies: high-efficiency power generation and consumption, intelligent optimization, and scenario integration. It says that this platform focuses on maximizing power plant revenue through enhanced power generation, multi-energy coordination, and optimized power trading operations. The intelligent optimization aspect uses digital tools to enable a full lifecycle digital management of power plants, from site selection and evaluation to design and operations. Lastly, the scenario integration technology allows the power plant to better serve production and daily life needs, harmonizing with the surrounding ecological environment.
BOE launches industry's largest perovskite module
Hefei BOE Optoelectronics Technology Co., Ltd., (BOE Optoelectronics) a subsidiary of the global semiconductor display manufacturer BOE, has successfully produced the industry's first 1.2 m x 2.4 m perovskite module. BOE Optoelectronics claims that it has fully implemented automatic and intelligent production lines, mastering the dry coating process. Currently, their glovebox champion efficiency stands at 25.6%, compared to the global record of 26.7%, while their experimental line champion efficiency reaches 20.63% (with the world record being 22.57%). This production line is the industry's first fully automated 1.2 m x 2.4 m perovskite thin-film solar cell line. BOE Optoelectronics highlighted that the entire process, from production line planning and equipment selection to installation and testing, was independently managed, featuring advanced automation and intelligent production equipment.
CPIA Calls for an end to below-cost module sales
In its latest announcement, the China Photovoltaic Industry Association (CPIA) says that bidding and winning contracts for solar modules below production costs may be illegal. Citing relevant articles from the ‘Law of the People's Republic of China on Bidding and Tendering’ and its implementing regulations, the CPIA highlighted that awarded contract prices must exceed production costs; otherwise, the evaluation committee should reject such bids.
Based on a cost analysis that includes polysilicon, silicon wafers, cells, and various auxiliary materials, the CPIA determined that as of October 2024, the tax-inclusive production cost of n-type M10 size bifacial double-glass solar modules manufactured by vertically integrated enterprises is RMB 0.68/W ($0.0956/W) (excluding logistics fees, depreciation, and tax). To ensure quality and the long-term stability of the market, the CPIA urges tender issuers to adopt measures such as setting minimum bid prices, reducing the weight of price scores in evaluations, and increasing the emphasis on service and quality in bid assessments. Additionally, the association calls on manufacturers to refrain from participating in bids or sales at prices below cost.
CPIA also mentioned that if a tender result violates the Bidding Law, it will explore solutions through administrative oversight and legal channels. It expressed concerns over potential quality issues and contract fulfillment challenges that may arise from bids awarded below cost. The association is prepared to take industry-wide actions, such as issuing public notices and reporting to market regulatory authorities, to enhance self-discipline and promote healthy industry development.
Furthermore, the CPIA announced plans to conduct regular industry cost surveys and publish the findings to provide a reference for the industry and government regulatory bodies.
