August 22nd, QW SOLAR (SZ. 300716) received good news from its Zaozhuang base in Shandong province: it has achieved mass production and delivery of the "GIWA 5" series 710W high-efficiency heterojunction (HJT) modules.

Since the release of HJT modules in February this year, QW SOLAR has utilized low-silver content paste and optical film encapsulation technology for its products. Continuous optimization and design improvements have been made to the cell gridline and spectral matching, resulting in a maximum power output of up to 730W and an impressive conversion efficiency of 23.5% for the modules.

QW SOLAR has always positioned itself as a technological innovator and leader, committing significant resources to establish an independent and autonomous technology research and development system. The Shandong R&D Center has gathered numerous top industrial talents, including scientific PhDs, research experts, and technical engineers, etc. While focusing on cutting-edge solar energy product technologies such as N-type HJT and industry-leading energy integration solutions, there is also continuous investment in the research and innovation of perovskite tandem cells. It is expected that in the next 3-5 years, with the gradual maturation of perovskite tandem cells at application level, there will be a qualitative leap in cell efficiency.
QW SOLAR has successfully overcome all obstacles in key technologies such as 0BB and 90μm thin wafers. Currently, it is in small-scale trial production. According to calculations, the combination of HJT 0BB with low-silver content paste technology will make product costs equivalent to those of TOPCon. At that time, the HJT capacity is expected to experience a significant surge.
Currently, QW SOLAR has established and owns the Shandong base (Zaozhuang City), Anhui base (Sixian County), and Shanghai S&M Center. In the future, it will also invest in building up bases in Guangdong and Northwest China, forming a pattern of four major bases and one S&M center. The first phase of 6GW high-efficiency HJT PV modules at Shandong base has gradually achieved mass production, while the construction of its Anhui base is underway. Once QW SOLAR’s Shandong and Anhui bases are fully completed, it will equipped with a production capacity of 10GW for high-efficiency HJT PV cells and 20GW for high-efficiency HJT PV modules.
