LONGi's latest HJT back contact cell research published in Nature

Leading solar manufacturer LONGi recently published a research paper titled Silicon heterojunction back contact solar cells by laser patterning in Nature, reporting a breakthrough in silicon solar cell technology. The research details how an all-laser patterning process enabled silicon solar cells to achieve over 27% photoelectric conversion efficiency for the first time. The R&D team developed a novel dense heterojunction (HJT) passivated contact, surpassing the industry’s previous bottleneck of 180-210°C in heterojunction preparation, reaching a process temperature of 240°C. Additionally, they introduced a low-indium, silver-free metallization solution using the laser patterning process. LONGi stated that this achievement represents a new milestone in photovoltaic technology based on silicon materials.

LONGi has expanded its Hi-MO solar module series with the introduction of Hi-MO X10 panels, offering a power output of up to 670 W and an efficiency of 24.8% (see LONGi ‘Breaks’ Global Module Mass Production Efficiency Record).

Meike Solar's IPO fails

According to information from the Shenzhen Stock Exchange, the status of solar ingot and wafer manufacturer Meike Solar’s IPO application has been updated to ‘suspended.’ Meike Solar initially submitted its IPO application in June 2022, which was accepted, and in December of that year, it passed the listing committee meeting. The company submitted its IPO registration documents in November 2023, but no further updates occurred until the status changed to ‘suspended’ on September 30, 2024, indicating a failed listing. Meike Solar had aimed to raise RMB 5 billion (694 million) to support phase 3 of its 20 GW monocrystalline ingot project at its Baotou, Inner Mongolia production base, as well as to supplement working capital. The company currently operates multiple wafer and module production bases in Jiangsu, Inner Mongolia, Yunnan, Sichuan, Zhejiang, and Vientiane, Laos, with a production capacity of 56 GW for large-size high-efficiency silicon wafers and an additional 4 GW of module capacity under construction.

Jinergy's special scenario solar module development project approved

PV manufacturer and clean energy provider Jinergy, in partnership with Taiyuan University of Science and Technology, has received approval for its project called ‘Development of Solar Modules for Special Scenarios’ from the Technology Bureau of Lüliang City, Shaanxi Province. The project focuses on adapting solar modules to extreme environments, including high temperatures, high humidity, strong UV radiation, heavy snowfall, and sandstorms. The goal is to promote large-scale application of the products in such special scenarios through optimized material selection and structural design. The development will include UV-resistant modules, high-pressure-resistant modules, and dust-resistant modules, targeting specific environmental challenges.

In May, Jinergy received TUV Nord certification for its 210R rectangular and 210 square n-type TOPCon modules (see China Solar PV News Snippets).

Taiheyuan breaks ground on 1.5 million ton solar glass plant

Solar glass manufacturer Taiheyuan New Energy Technology Co., Ltd. has commenced construction on an office building for its solar glass production project in Lanzhou City, Gansu Province. The project, with a total investment of RMB 4.5 billion ($625 million), spans 1,503 acres and includes plans for 4 production lines, each with a 1,200-ton per day capacity. The facility will feature a single furnace with 5 lines for photovoltaic rolled glass production. Taiheyuan New Energy also plans to utilize waste heat from the production lines for power generation. The project is expected to start production in April 2026 and, once fully operational, is estimated to achieve an annual output value of RMB 5 billion ($694 million).

RESOLAR to invest in 140,000-ton PV module recycling facility

Solar module recycling company RESOLAR has signed an investment contract with the People's Government of Luoshan County, Xinyang City, Henan Province for a 140,000-ton retired PV module and production line waste recycling and reuse facility in Shanghai. With a total investment of RMB 180 million ($25.3 million), the facility will include PV recycling, recycled silicon material production, ingot casting and wind power material recycling production lines.
