Huasun's Revolutionary 0BB Heterojunction Solar Modules





In the rapidly evolving world of solar energy, Huasun Energy is setting a new benchmark with its latest unveiling: the 0BB Heterojunction (HJT) Solar Modules. This innovative leap forward incorporates cutting-edge zero busbar (0BB) technology, marking a significant milestone in the quest for more efficient, reliable, and cost-effective solar solutions. Huasun, recognized as the global leader in HJT product manufacturing, has seamlessly integrated this groundbreaking technology into its mass production lines, including the renowned Himalaya G12 Series and Everest G12R Rectangular Series. The introduction of 0BB technology heralds a new era in solar module design, offering unparalleled electrical, optical, and temperature coefficient performance enhancements.



The essence of 0BB technology lies in its innovative approach to module construction. Traditional solar modules rely on busbars to connect and support the flow of electricity, which can introduce resistance and inefficiencies. Huasun's 0BB design eliminates this need, employing advanced welding and dispensing techniques for superior adhesion, resistance to hot spots, and a carrier film-free configuration. The result is a product that not only boasts higher efficiency and power output but also sets a new standard in module reliability and longevity.

In the manufacturing sphere, Huasun's adoption of a simplified two-step screen print (SP) technology further underscores its commitment to excellence. This method enhances the electrical and cell-to-module (CTM) performance, positioning Huasun's 0BB modules well ahead of their super multi-busbar (SMBB) counterparts. With improvements in open-circuit voltage (OCV), conversion efficiency, and module power output, Huasun is at the forefront of the solar industry's drive towards higher performance standards.



Huasun's 0BB modules exemplify the company's dedication to innovation. By employing front-layer welding, these modules achieve reduced contact resistance and a lower hot-spot temperature, thereby ensuring greater module reliability. Additionally, the design's minimized metal coverage on the back enhances the light-receiving area, achieving an impressive bifaciality of up to 90%. This not only maximizes the efficiency of each module but also contributes to the overall sustainability of solar energy systems.

As the solar industry moves towards the use of thinner silicon wafers, the 0BB technology's ability to provide higher reliability without the need for a main grid becomes increasingly crucial. Huasun's modules leverage downshifting (DS) light conversion encapsulation and PIB edge sealing technology, delivering a significant boost in power generation capacity. For project owners across utility, commercial & industrial (C&I), and residential sectors, this advancement means more dependable, higher-performing photovoltaic solutions.


The successful mass production of Huasun's "G12+0BB" and "G12+R+0BB" HJT products is not just a testament to the company's innovation prowess; it's a beacon for the future of solar technology. By pushing the boundaries of efficiency and reliability, Huasun continues to champion the industrialization of HJT technology. The widespread adoption of 0BB high-efficiency modules promises a future where solar energy is more accessible, cost-effective, and impactful.



Huasun's unveiling of its 0BB Heterojunction Solar Modules represents more than a technological breakthrough; it embodies the company's vision for a sustainable, energy-efficient future. As the world gravitates towards greener solutions, Huasun's innovations are paving the way for the next generation of solar energy. With higher conversion efficiency, enhanced reliability, and lower Levelized Cost of Electricity (LCOE), Huasun is not just leading the charge towards a brighter tomorrow—it's redefining what's possible in the realm of solar energy.
