AIKO will unveil its fourth-generation Infinite Ultra module at Intersolar Europe 2026, marking the latest milestone in the company’s ABC (All Back Contact) technology roadmap. The new module brings mass-production performance into the 690W era, while increasing module efficiency to 25.6%.
The launch comes as BC technology gains growing momentum across the global solar industry. Since introducing its first ABC module in 2022, AIKO has remained focused on advancing N-Type BC technology and building an ecosystem together with partners across the solar value chain. Today, the company’s ABC modules are shipped to 79 countries across five continents through a network of 92 tier-one distribution partners. In Europe’s residential solar market, ABC has achieved more than 21% market share, while AIKO has secured over 19GW of utility-scale project awards and established partnerships with 25 key global energy players.
Market adoption has accelerated rapidly, with ABC module shipments growing from more than 700MW in 2023 to 6.3GW in 2024 and 14.7GW in 2025.
The development of ABC technology has been driven by a continuous pursuit of higher energy conversion efficiency. The first-generation ABC module, launched in 2022, introduced a full light-receiving front surface, full-passivation and an all-back-contact architecture, delivering 570W and 22.1% module efficiency. In 2023, the second generation introduced high-resistivity, low-oxygen wafers and a 20-busbar (20BB) cell architecture, raising performance to 640W and 23.7% efficiency. By 2025, AIKO had achieved full-scale commercialization of its third-generation Infinite platform, combining ultra-high-resistivity, low-oxygen wafers, zero-busbar (0BB) technology and proprietary full-screen technology to deliver up to 680W and a module efficiency exceeding 25%.
Building on this foundation, the new Infinite Ultra further improves both cell efficiency and module integration. By increasing cell performance and reducing non-active module areas, the design enables higher power output within the same module dimension, pushing module efficiency to 25.6%.
