HIBC

Champion Technology Driving an Era of Transformation

HIBC (Hybrid Interdigitated Back-Contact) refers to a high-low temperature composite passivated back contact technology. Building on LONGi’s extensive experience in back-contact (BC) technology, HIBC fully leverages the high compatibility of BC structures to enable innovative application of hybrid passivation at both high and low temperatures. In April 2025, certified by Germany’s Institute for Solar Energy Research Hamelin (ISFH), HIBC cells reached a conversion efficiency of 27.81%, setting a new world record. As champion technology, HIBC has delivered breakthroughs in materials science, pioneered new paradigms in structural design, and revolutionized mass production processes for BC technology. Module products based on HIBC boast a power output exceeding 700W with a golden size of 2382mm × 1134mm. With mass production module efficiency approaching 26%, HIBC is comprehensively ushering the photovoltaic industry into the "25%+" efficiency era.

Every Figures Speaks Volumes

True 700W+

Achieving 700W+ Ultra-High Power With a 2382 × 1134 Golden Size Compared with other 700W modules of the same power in the industry (most of the sizes are 2384mm×1303mm or larger) This module has an area 0.4㎡ smaller But the power density is higher Thoroughly overthrowing the industry’s entrenched logic That "larger size equals higher power."

Power Density: 259W+/㎡

LONGi First Proposes 'Power Density' Emphasizing Wattage Per Square Meter To Cut Through The Illusion That “Bigger Size Equals Higher Power Focusing Instead On A Module’s True Efficiency The HIBC 700W Module Leads The Industry In Power Density At 259W/㎡ 34W/㎡ Higher Than Comparable Industry Modules

Sustained Leadership: 30W+ Advantage

LONGi’s HIBC Ultra-High-Power Modules Achieve Mass Production Power Output of 700W+ 30W Higher Than The Industry-Average TOPCon Modules Building On HPBC To HIBC LONGi’s BC Modules Again Break Power Output Records Maintaining A Consistent 30W+ Lead In The Market

Ushering In The 25%+ Efficiency Era

Powered by HIBC Technology LONGi EcoLife Series Achieves up to 25% Efficiency While its 700W Module Reaches 25.9% — 2.4 Percentage Points Higher Than The Average Efficiency Of TOPCon Modules This Milestone Confirms That LONGi’s HIBC Technology Is Leading The Industry Into The 25%+ Efficiency Era
