IBC Technology solar panels

The next generation solar panels has arrived

Revolutionizing the solar landscape with IBC

Unlock solar efficiency and aesthetics with state-of-the-art Interdigitated Back Contact (IBC) technology solar panels. IBC represents a breakthrough in solar panel design by positioning all electrical contacts at the back of the solar cell. This approach enhances the panel’s visual appeal and dramatically increases its efficiency, achieving a peak conversion efficiency of over 26% for solar energy. By maximizing the active surface area, this innovative configuration allows for superior solar power conversion.

These panels significantly reduce shading losses by eliminating front-side metal contacts, thereby increasing light absorption and elevating power output per square meter. Such design advances ensure that IBC panels deliver consistently high performance even in low-light conditions, making them exceptionally efficient.

Built to endure, IBC panels offer enhanced durability. They are engineered to withstand the most challenging environmental conditions, including moisture and extreme temperature fluctuations. This robust construction extends the lifespan of the panels and ensures sustained performance over time.

Optimized for high temperatures, this technology excels in maintaining efficiency even on the hottest days, thanks to their low-temperature coefficients. This feature is crucial in hot climates, where solar panels typically suffer from efficiency losses.

IBC versus other technologies: PERC, HJT and TOPCon

IBC technology not only meets but exceeds the capabilities of traditional systems such as PERC with its exceptional power output and robust design. It provides a seamless upgrade path on existing production lines, ensuring lower initial investments and simpler transitions. This ease of integration, combined with superior efficiency and durability, makes IBC panels a compelling choice in the competitive solar market, offering a blend of high performance, long-term reliability, and aesthetic appeal.

PERC technology uses a passivated film at the back of the cell to improve light absorption but still features front-side metal contacts which can lead to shading losses. IBC, by contrast, relocates all contacts to the rear, completely eliminating front-side shading and often resulting in higher overall efficiency.

While HJT is renowned for its high efficiency and excellent low-temperature performance, the manufacturing process is complex and costly. IBC offers a simpler and often more cost-effective upgrade to existing manufacturing lines, making it an attractive alternative for large-scale production without the need for completely new equipment.

TOPCon technology applies an ultra-thin insulating layer and a doped polysilicon layer on the back of the cell to reduce recombination losses and improve efficiency. While both TOPCon and IBC technologies enhance cell efficiency and longevity, IBC’s rear-contact design avoids any potential shading issues on the cell surface, potentially offering better light absorption capabilities.

The future of IBC technology

The transition to IBC technology represents a strategic investment into the future of solar energy. The solar energy market is witnessing significant technological shifts, notably with IBC and TOPCon technologies. Current projections suggest that while TOPCon is set to represent around 29% of the total module shipments this year, IBC technology is poised for rapid growth. Market analysis forecasts IBC’s share to expand from roughly 2% in 2022 to 6% by 2026, eventually reaching 20% by 2028, and surpassing 50% by 2030.
