As one of the advanced solar technologies exclusively represented by our factory, BC (Back Contact) battery technology is gaining increasing popularity in the solar industry due to its superior performance and aesthetic advantages. This technology significantly enhances solar cell efficiency and reliability through a front-side gridless design, simplified packaging process, and attractive appearance.

 

 

Three Key Benefits of BC Batteries

 

1. Free Grid Design: Enhanced Photovoltaic Efficiency

 

BC batteries' grid-free front design eliminates shading losses, maximizes light absorption, and increases short-circuit current (Jsc) by approximately 7%.

 

2. Simplified packaging: improved anti-cracking performance

 

By replacing the traditional "Z" weld with a full rear-side "I" weld, BC batteries simplify the packaging process and improve the module's resistance to microcracks.

 

3. Aesthetic appearance: Uniform tone

 

The absence of gridlines on the front creates a smoother surface, making the battery more visually appealing and meeting modern aesthetic standards for solar products.

 

 

Example: Rooftop project in Stockholm, Sweden

 

A rooftop solar project in Stockholm successfully applied BC technology, increasing power generation efficiency and becoming a landmark in sustainable architecture due to its attractive appearance. As our only representative product, the performance of BC batteries in real-world applications further verifies their technological advantages and market potential.

 

Comparison with Other Technologies

 

Compared to PERC, TOPCon, and HJT technologies, BC batteries excel in both efficiency and aesthetics. However, their manufacturing process is more complex, resulting in higher production costs. Our factory's exclusive BC batteries, with their high efficiency and excellent appearance, have become a highly sought-after solar battery solution in the market.

 

Challenges and Future of IBC Batteries

 

IBC (Interdigitated Back Contact) batteries are known for their complex manufacturing processes and higher costs. However, their superior performance makes them a promising option in the high-end market, and with ongoing technological advancements, IBC batteries are expected to experience significant growth.

 

Looking Ahead

 

BC and IBC battery technologies are set to drive the solar industry towards greater efficiency and sustainability, contributing to the global transition to clean, renewable energy. As products exclusively represented by our factory, the widespread adoption and application of these technologies will open up more market opportunities and contribute to the future of the solar industry.
