Integrated solar manufacturer JinkoSolar has announced that it has achieved new efficiency records for its n-type TOPCon cells and modules. First, its TOPCon module developed in-house set a ‘world record’ for n-type TOPCon module efficiency, achieving a maximum conversion efficiency of 25.58%. Certified by TÜV SÜD, the company says this achievement sets a new global benchmark for modules in this category.
In addition, Jinko’s 182 mm n-type monocrystalline silicon TOPCon cell achieved a certified full-area conversion efficiency of 27.02%, based on third-party testing by the National Center of Supervision and Inspection on Solar Photovoltaic Product Quality. The company calls this ‘a new record’ for large-area n-type TOPCon solar cells.
JinkoSolar stated that it plans to complete capacity upgrades for more than 40% of its production lines this year, targeting 40-50 GW of high-power TOPCon capacity by the end of 2025. Its latest generation of high-efficiency TOPCon products can deliver up to 670 W of power output, with module efficiency reaching 24.8% and a bifaciality rate as high as 85%.
Earlier this month, JinkoSolar, in collaboration with CGC and TÜV NORD, released the ‘industry's first’ comprehensive white paper on TOPCon solar technology and its Tiger Neo 3.0 solution (see China Solar PV News Snippets).
Heterojunction (HJT) cell and module manufacturer Grand Sunergy has signed a major sales agreement with China General Nuclear Power Group (CGN). According to the company’s latest announcement, its subsidiary entered into a framework procurement contract with a CGN subsidiary for the supply of solar modules in 2025. The total contract value, including taxes, is RMB 1.0425 billion ($144.8 million). According to the agreement, Grand Sunergy will supply its PV modules to CGN from the date of signing through December 31, 2025. The company has not disclosed details about capacity and product specifications at this time.
In April, Grand Sunergy announced the successful rollout of the first module from its Laizhou HJT module production facility (see China Solar PV News Snippets).
The environmental impact assessment (EIA) document for Phase I, Stage I of Jiangmen Pule Kairui Solar Technology Co., Ltd.’s n-type solar cell manufacturing project has been officially accepted by the local Ecology and Environment Bureau. According to the EIA filing, the company plans to build a high-efficiency n-type solar cell manufacturing facility in Jiangmen City, Guangdong Province. The project will spread over an area of 334,104.91 square meters and will consist of 10 production lines. While the current EIA approval pertains to the initial 2 GW phase, the project aims to achieve an annual output capacity of 5 GW of ultra-high-efficiency n-type solar cells.
China General Certification Center (CGC) has released a white paper titled Mechanical Load Performance Evaluation of Photovoltaic Modules. It offers a comprehensive evaluation of the mechanical stress PV modules face during long-term outdoor operation based on the latest research findings, international and enterprise standards, as well as laboratory test data. It focuses on static and dynamic mechanical loads across various application scenarios, including special operating conditions. The paper also provides an in-depth analysis of testing objectives, methodologies, and data interpretation for different types of mechanical load testing in PV modules.
