Beyond standard conditions, Hi-MO 9 demonstrates exceptional resilience in challenging environments such as partial shading, high-temperature/high-humidity regions, and low-light scenarios. Over the past year, multiple field demonstration projects have revealed the Hi-MO 9 module’s "remarkable" energy generation capabilities across varied environments. In Hainan, China’s high-temperature, high-humidity environment, LONGi’s Hi-MO 9 module delivers a 1.89% per-watt energy yield advantage over conventional TOPCon modules. In arid Riyadh, Saudi Arabia, the gain reaches 1.62%. Data from additional BC power plants further confirm the exceptional power generation capabilities of the HPBC 2.0-powered Hi-MO 9 module, underscoring its proven reliability across diverse global climates.
World Record Broken: Photovoltaic Efficiency Reaches New Heights
At the event, LONGi announced a groundbreaking achievement in high-efficiency PV cell technology, setting an unprecedented world record:
• 27.81% Conversion Efficiency for its self-developed HIBC (Heterojunction Interdigitated Back Contact) silicon solar cells, certified through rigorous calibration tests by Germany’s ISFH (Institute for Solar Energy Research Hamelin).
The achievement not only reignites global market optimism toward cutting-edge solar solutions but also solidifies LONGi’s role as a trailblazer in delivering transformative energy technologies.
Unlocking Greater Commercial Value: Global Optimal BC Solar Power Plant Design Challenge Launched
To further amplify the market potential of high-efficiency BC technology, LONGi partnered with TÜV Rheinland, a globally renowned third-party institution, to launch the “Global Optimal BC Solar Power Plant Design Challenge”during the event. The competition, open to consultancies, EPC firms, and renewable energy investors worldwide, invites innovative designs for ground-mounted power plant projects exceeding 50MW across diverse application scenarios. Submissions will be accepted from April 11 to November 30, 2025. TÜV Rheinland will lead an expert panel in rigorously evaluating entries based on BC technology integration, PVsyst simulation results, and design innovation. The total prize purse amounts to approximately 280,000 USD. (Click Here for Challenge Detail )
