Thin-film power solution company Hanergy Thin Film Power Group, jointly announced with Chengdu Zhufeng Yongming Technology Company that Institute for Solar Energy Research in Hamelin (ISFH), the German testing body has certified its silicon heterojunction thin film battery technology (SHJ technology) as the world’s most efficient. With its record setting 24.85% conversion efficiency, Hanergy’s SHJ Technology is primarily used in ground power stations, distributed power stations, vertical installation, fishery or agricultural complementary photovoltaic power stations, building-integrated photovoltaics (BIPV) and mobile energy projects.
“Following this recent development, not only has Hanergy refreshed its Chinese record (24.23%), but has also surpassed the original world record of 24.5% maintained by Japan Kaneka, becoming the new world champion of 6-inch silicon SHJ battery,” the company said.
It further adds, SHJ technology is deemed to be a competitive solar technology in the future. Its components have excellent weather resistance and have a lifespan of more than 30 years. They are attributed to many advantages such as high conversion rate, stable performance, no light decay, no potential induced attenuation (PID), and high power output at high temperatures.
Zhang Bin, Hanergy’s senior vice president said, “As a global technology forerunner in renewable energy sector, we’re bound to take a notch higher in the industry through our technological breakthroughs. Setting a new world record for SHJ technology is a testimony of our constant efforts to better our technology and to make the world greener. We’ll continue to set new benchmarks in the industry.”
According to Hanergy, the clean energy giant wholly owns the IP right of the production line and turn-key project. The record-breaking Hanergy SHJ battery uses LONGi high-quality N-type silicon wafer as the base, amorphous silicon membrane and Silicon carbon alloy thin-film for the passivation layer, and microcrystalline silicon oxide material for the window layer. Combined with Hanergy’s world leading thin-film technology, the battery significantly improved open-circuit voltage and short-circuit current, achieving steady breakthrough in SHJ battery conversion efficiency. Hanergy’s SHJ battery uses the low-cost ITO Film and screen-printed electrode that can be purchased easily, gaining an edge in reducing production cost and market expansion.
