AIKO Launches INFINITE ULTRA and Z Series, Extending the Boundaries of BC Technology
June 23rd, 2026
AIKO unveiled two new product series at Intersolar Europe 2026: the fourth-generation INFINITE ULTRA and the Z Series. Together, they set new benchmarks for mass-produced photovoltaic modules, with the INFINITE ULTRA achieving efficiency of 25.6% and power output of up to 690W.
Building on the proven technologies of the G3 INFINITE series, including InvisiRibbon Technology, ZeroGap Technology, with using low dopant, high resistivity wafers, the fourth-generation INFINITE ULTRA introduces a new round of innovations at both cell and module level, pushing power output and efficiency to new highs without increasing module dimensions.
At the cell level, AIKO has increased average mass-production cell efficiency from 27.2% to 27.4%, contributing approximately 5W of additional module power. The improvement is not the result of a single breakthrough, but of multiple refinements throughout the cell manufacturing process, including front surface texturing reconstruction, trench structure optimization, tunnel oxide engineering, texturing optimization under the poly-Si layer, advanced hydrogenation, and poly-Si layer enhancement. Each individual improvement contributes only a fraction of a percentage point. Together, they demonstrate AIKO’s continued commitment to extracting every possible increment of efficiency from the ABC technology platform.
At the module level, AIKO has further reduced non-cell area by 20% compared with the previous generation. This enables more active photovoltaic area within the same module dimensions, contributing an additional 7W of power output.
Achieving this reduction required overcoming one of the industry’s longstanding technical barriers: reducing creepage distance without compromising reliability or safety. Historically, attempts to minimize inactive module areas have faced three major challenges: insulation breakdown…
