A few days ago, Hanergy Group's high-efficiency silicon heterojunction thin-film battery technology (referred to as "SHJ technology") champion cell (156mm X 156 mm) photoelectric conversion efficiency reached 24.23% by the Japanese testing agency JET certification, once again refreshing its maintained Chinese record , And ranked among the world's most popular. This is another major breakthrough in Hanergy's thin-film solar technology after Hanergy's gallium arsenide thin-film single-junction cell conversion efficiency set a world record of 29.1% and was taken to the International Space Station by NASA.
It is understood that in the past two years, the efficiency of Hanergy SHJ batteries has continuously increased by 1% per year. In August 2018, the efficiency of mass-produced Hanergy SHJ cells was certified by Japan JET to 23.7%, and was included in the China Renewable Energy Academic Conference as the highest efficiency of heterojunction solar cells in China in 2018. This time, Japan ’s JET-certified mass-produced Hanergy SHJ battery has an efficiency of 24.23%, which once again sets the highest record in the country, further establishing Hanergy ’s leading position in the field of high-efficiency thin-film batteries, and has a positive significance for reducing product costs and developing markets. .
As one of Hanergy's thin-film solar technology routes, SHJ technology inherits Hanergy's long-term accumulated experience in amorphous silicon, microcrystalline silicon and TCO thin-film technology; led by world leaders in the frontier field of solar energy, it has built a young The R & D team of young scientists with rich experience in the industry, after several years of perfect experimental conditions and technological accumulation, the technology has begun to make breakthrough progress. At present, more than 300 related patents have been applied for, of which more than half are invention patents.
SHJ technology is known as the very competitive next-generation solar technology. The components produced based on SHJ technology have excellent weather resistance and a life span of more than 30 years. At the same time, they also have many advantages such as high conversion efficiency, stable performance, no light attenuation, no potential induced attenuation (PID), and high power output at high temperatures. It is mainly used in projects such as ground power stations, distributed power stations, vertical installation, fish-light complementary, agricultural-light complementary, building integration (BIPV) and mobile energy. Hanergy's SHJ technical team said that it will continue to explore in terms of technology integration and product development to provide the industry with the best efficient photovoltaic mass production products and solutions.
At present, including SHJ technology, Hanergy has five technical routes in the field of thin-film solar energy, and the photoelectric conversion rate continues to break records. The conversion rate of glass-based large-area copper-indium-gallium-selenium thin-film modules manufactured by Hanergy subsidiary Solibro reached 18.72%; the conversion rate of flexible copper-indium-gallium-selenium thin-film modules manufactured by the subsidiary MiaSolé by sputtering method reached 19.4%, the highest in the world Level. The gallium arsenide technology has achieved a major breakthrough in 2018. According to the Fraunhofer ISE, one of the three major renewable energy research institutions in the world, Hana Alta Devices' gallium arsenide thin film Junction cell conversion efficiency has now reached 29.1%. So far, Hanergy has maintained a number of global leading levels in the field of gallium arsenide batteries, including double-junction batteries (31.6%), single-junction batteries (29.1%), and mass-production components (25.1%). As of now, Hanergy has applied for more than 10,100 patent applications worldwide.
Since entering the field of thin-film solar energy in 2009, Hanergy has become the global thin-film solar energy industry through eight years of hard work through the implementation of the innovation-driven strategy of “mergers and acquisitions of global core technologies—digestion and absorption, integrated innovation—formation of core technologies with independent intellectual property rightsâ€. The leader is not only the scale, but also the core technology. Relying on advanced thin-film solar technology, Hanergy has created a brand-new mobile energy industry, and fully covered the terminals for housing, transportation and use through Hanwa, Hanqiang, Hanlu, Hanbao, Hanzhi, Hanzhu, Hanche, etc. Products, provide clean power solutions for various industries, and realize "let all things generate electricity".
