LONGi Hi-MO X10 Revolutionizes Solar with pv magazine Award for Back-Contact Innovation

LONGi Hi-MO X10 Module Secures Prestigious pv magazine 2025 Award for Back-Contact Innovation

LONGi has been honored with the distinguished pv magazine 2025 Award in the ‘Modules’ category for its groundbreaking Hi-MO X10 module, featuring advanced back-contact technology. This annual award, established by a panel of independent experts, is a globally recognized accolade within the photovoltaic industry. The jury specifically lauded the Hi-MO X10's technological innovation, highlighting its superior bifacial performance and its success in overcoming the long-standing limitations of back-contact designs while delivering exceptional real-world efficiency.

Jury Commends Optimizations Boosting Rear-Side Performance to 75%

Traditionally, achieving high bifacial performance in back-contact designs presented challenges due to the placement of electrical contacts on the rear of the cell. The pv magazine awards jury recognized how the Hi-MO X10 module effectively addresses this limitation through a series of targeted design optimizations. These advancements have reportedly increased the module's rear-side performance ratio to 75%, enabling robust energy generation from both sides of the cell, even with its back-contact architecture. The jury also praised the module for its adeptness in leveraging the technology's inherent advantages, such as excellent shading tolerance and remarkable performance in low-light conditions.

HPBC 2.0 Technology Sets New Efficiency Benchmarks Beyond TOPCon

The award further underscores the significant technological advancements powering LONGi's HPBC 2.0 platform, which underpins the Hi-MO X10. Built upon second-generation Hybrid Passivated Back Contact (HPBC) cells and the TaiRay wafer, this module achieves a mass production efficiency of up to 24.8%, surpassing the performance levels of conventional TOPCon modules. The busbar-free design not only enhances the module's aesthetic appeal but also maximizes light absorption by eliminating front-surface grid lines. These technological breakthroughs ensure that the Hi-MO X10 generates more power per square meter, positioning it as a superior choice for a diverse range of applications, including commercial and industrial installations.

For residential use, the 54-cell variant of the Hi-MO X10 is integrated into LONGi's EcoLife series, specifically engineered to meet the performance, reliability, and design demands of contemporary homeowners.

Real-World Benefits Driven by Enhanced Shading Behavior and Thermal Response

Beyond its celebrated bifacial performance, the Hi-MO X10 demonstrates significant advantages in practical operational scenarios. Its 'soft breaking' behavior mitigates the risk of hotspots under partial shading, a critical factor influencing long-term system reliability. Under shaded conditions, the module's design can reduce power losses by over 70% compared to standard TOPCon products.

Furthermore, the module benefits from an improved temperature coefficient of -0.26%/°C, facilitating stable energy yield in high-temperature environments. Collectively, these features highlight the relevance of back-contact technology not only at the cell level but also in the practical, day-to-day operation of solar systems across varied climatic and installation conditions.
