HETEROJUNCTION (HJT) TECHNOLOGY SET TO REVOLUTIONIZE SOLAR INDUSTRY WITH its high-efficiency and long-term performance credentials
In a significant milestone for the solar energy sector, heterojunction technology is transforming the industry with its unparalleled efficiency and superior long-term performance. But what sets it apart from other technologies like PERC (Passive Re-Cell) and TOPCon (Tunnel Photodetector-based Cell)?
Huasun, a leading global solar panel manufacturer, has recently shed light on their cutting-edge HJT solutions in a new series titled "All About Heterojunction". According to the company's latest innovation, efficiency meets innovation in the world of solar energy.
Unique Hybrid Structure
At the heart of Huasun's HJT technology lies an innovative hybrid structure. The n-type crystalline silicon (c-Si) wafer is sandwiched between intrinsic amorphous silicon (i-a-Si:H) layers, which provide exceptional performance benefits:
- Natural Bifacial-symmetrical Structure: The distinctive material properties and inherent bifacial symmetrical structure of HJT solar cells allow for improved light capture from both sides, resulting in increased power generation.
- Higher Cell Efficiency: By reducing recombination and optimizing charge separation, Huasun's HJT technology boosts energy conversion efficiency.
Transformative Evolution of HJT Technology
With its origins dating back to 1990 by Sanyo Corporation of Japan, HJT technology has been industrialized since the 2010s. Over the past three decades, it has consistently achieved record-breaking photovoltaic efficiencies, setting a new standard for solar cell technology.
Simplified Production and Superior Bifacial Generation
In contrast to conventional materials like PERC and TOPCon, which require multiple complex steps in production, Huasun's HJT manufacturing process is streamlined into just 4 simple steps. This approach yields significant cost savings, increased production efficiency, and reduced energy consumption.
The company's HJT modules also boast exceptional bifacial generation capabilities, delivering up to 2-5% higher energy yield per watt compared to identical bifacial TOPCon modules under similar conditions.
Innovative Application of HJT
HJT technology offers a wealth of benefits for vertical installations. Its remarkable efficiency and power output make it an ideal choice for energy-intensive applications such as agricultural farms, rangelands, and highway guardrails. Additionally, these modules feature extremely low operating and maintenance costs, underscoring their exceptional overall economic viability.
Huasun's commitment to pushing the boundaries of HJT technology will undoubtedly boost confidence in solar energy's future prosperity.
