Additionally, the company collaborates with institutions such as Shanghai Jiao Tong University and Jiangsu University to co-supervise postgraduate programs, fostering talent development through academic-industry partnerships.

Eging International Science and Technology Cooperation Base

From June 2008 to June 2010, Changzhou Eging Photovoltaic Technology Co., Ltd. undertook a national-level international science and technology cooperation project in collaboration with Japan’s Noritake Co., Ltd., focusing on the joint development of a "mesh belt-free high-temperature sintering furnace system." This initiative aimed to optimize and enhance existing sintering furnace technologies. On September 19, 2008, the company was officially designated as an "International Science and Technology Cooperation Base" by the Department of International Cooperation, Ministry of Science and Technology of the People’s Republic of China. A grand ceremony was held at the Science and Education City to mark this recognition, during which Mr. Meng Shuguang, Deputy Director-General of the Department of International Cooperation, presented the accreditation plaque to Eging.

Eging CNAS-Accredited Laboratory

Established on May 1, 2007, the Module Testing Laboratory of Changzhou Eging Photovoltaic Technology Co., Ltd. specializes in evaluating raw materials and finished photovoltaic modules to ensure product quality and reliability. Equipped with over 100 advanced testing devices and instruments, the laboratory offers comprehensive testing capabilities, including 20 large-scale test categories and 96 small-scale test procedures. In October 2011, the laboratory was awarded the CNAS National Laboratory Accreditation Certificate by the China National Accreditation Service for Conformity Assessment (CNAS), demonstrating its full compliance with the ISO/IEC 17025 international standard and CNAS-CL01 accreditation requirements. This recognition underscores Eging’s commitment to maintaining globally benchmarked quality control systems.

Advanced Technology

LECO Technology

LECO Technology, also known as Laser-Enhanced Contact Optimization (LECO), utilizes high-intensity laser irradiation on solar cells to excite charge carriers. Simultaneously, a bias voltage is applied to generate localized currents, inducing sintering and significantly reducing contact resistance between metal electrodes and semiconductors, thereby improving the fill factor. By adopting LECO Technology, the efficiency of N-type solar cells can be enhanced by 0.35%, while N-type modules of the same design achieve even greater performance gains.

SMBB Technology

SMBB (Super Multi-Busbar) Technology increases the number of busbars on solar cells, shortening current transmission paths and minimizing shading losses, thereby expanding the active power-generating area of each cell. At the module level, SMBB Technology reduces risks of micro-cracks and solar cell breakage, significantly enhancing the reliability of photovoltaic modules.

High-Efficiency
Bifacial Technology

Bifacial Technology represents a significant advancement in photovoltaic performance. By leveraging dual-sided power generation capabilities, N-type modules deliver higher energy gains compared to P-type counterparts, achieving a bifaciality rate of up to 80%.
