Additional Product Advantages

HJT – High-Quality Solar Modules

Damage-free welding process

The solar cell soldering process employs temperatures below 250°C, minimizing the potential for heat-induced damage. This careful approach preserves the integrity of the solar cells, ensuring their optimal performance and longevity.

Optimal temperature coefficient

HJT cells are distinguished by their superior temperature coefficient of -0.24%/°C, maintaining higher power output even under elevated temperatures. This characteristic not only boosts electricity production but also contributes to a lower levelized cost of electricity (LCOE), enhancing overall system efficiency.

SMBB technology

Utilizing SMBB 18BB technology, HJT cells experience uniform stress distribution, which significantly diminishes the risk of micro-cracks by shortening the current transmission distance and minimizing power loss. This innovation bolsters the durability of HJT solar panels and notably augments their photovoltaic conversion efficiency.

No LID and LeTID Effect

Incorporating an anti-reflection layer with conductive ITO, HJT cells successfully counteract both LID and LeTID effects. Over a span of 30 years, these cells demonstrate minimal degradation below 11.1%, ensuring consistent and enhanced power generation over their entire service life.

PID Resistance

HJT cells feature a TCO (Transparent Conductive Oxide) coating without an additional insulating layer. This structural choice endows TCO with the ability to prevent potential-induced degradation (PID), securing the cells' efficiency and longevity.

30-Year Product Warranty

HJT solar panels utilize double-glass design, which provides excellent weather resistance, corrosion resistance, and durability. Additionally, the POE encapsulant film incorporated in these solar panels offers outstanding moisture barrier capabilities, anti-PID performance, and aging resistance. These features collectively contribute to a 30-year product and performance warranty for the HJT solar panels.

Non-cut Cell Technology

The manufacturing of HJT solar modules involves a novel half-cell processing technique that eschews the micro-cracks associated with cutting cells into halves, a frequent issue in conventional half-cell production. This approach significantly elevates the modules' performance reliability.

Enhanced Adaptability

With the incorporation of HJT technology, thin-film cells exhibit exceptional flexibility and an increased capacity to bend, significantly reducing the risk of hidden micro-cracks during transport and installation. This ensures the modules' structural integrity and reliability.

Superior Low-Light Efficiency

HJT cells integrate i-a-SiH thin films with crystalline and doped amorphous silicon, creating a defect-free crystalline silicon surface. This results in an exceptionally high open-circuit voltage (750 mV), facilitating efficient power generation even in low-light conditions such as early mornings.

Frequently Asked Questions

Discover More About HJT

Q: How did HJT technology evolve?

A: The journey of HJT technology began in 1974 when Waler Fuhs first introduced the concept of merging amorphous and crystalline silicon materials to create the HJT structure. Initial development was gradual, with Sanyo Group pioneering the first successful HJT solar cells in 1989 and securing a patent. These early HJT panels achieved a 15% efficiency rate. Sanyo’s 1997 trademark registration for HJT marked a commercial milestone, with Panasonic’s patent expiry in 2010 further accelerating development. This opened doors for various manufacturers to enhance HJT technology, leading to industrial-scale production and continuous efficiency improvements. By 2017, HJT technology had entered a commercial phase, with increasing adoption and production capacities exceeding 100 MW, highlighting a bright future for HJT cells.

Q: What is the fundamental principle behind the cells of HJT solar panels?

A: HJT cells employ a heterojunction structure, where amorphous silicon is layered onto an N-type silicon wafer, acting as a passivation layer to elevate open-circuit voltage and efficiency. An additional transparent conductive TCO layer enhances the cell’s performance. The manufacturing process benefits from low-temperature procedures, around 200 degrees for silver paste, facilitating the use of thinner N-type wafers and pointing towards potential cost reductions.

Q: What sets the cells of HJT solar panels apart in terms of advantages?

A: HJT cells are distinguished by their superior power generation capacity and efficiency potential. The technology’s streamlined manufacturing process, involving fewer steps than PERC and TOPcon technologies, significantly simplifies production and paves the way for cost savings. HJT’s symmetrical design promotes bifacial power generation, blending the best of crystalline silicon and thin-film technologies for a leap forward in solar innovation. Additionally, incorporating perovskite layers into HJT cells can further enhance their conversion efficiency, underscoring the technology’s leading edge in solar cell advancement.
