AIKO's latest efficiency milestone rests on a series of refinements at the cell level, where advanced passivation optimisation has further enhanced intrinsic efficiency. By refining material systems and deposition processes, the company reduces carrier recombination, while tighter process control minimises damage in subsequent manufacturing steps. This delivers higher open-circuit voltage and improved fill factor, laying the foundation for efficiency gains.
KEY 2026 – industry presents more durable TOPCon, BC and ABC designs
In metallisation and interconnection, AIKO has brought zero-busbar (0BB) technology into mass production. By eliminating conventional busbars and routing current collection through fine fingers, the design shortens current paths and cuts resistive losses. In turn, this lowers series resistance and further improves fill factor, contributing directly to higher cell efficiency.
Maximise the use of the encapsulation area
At the module level, AIKO has industrialised its proprietary full-screen (INFINITE) integration approach. The design eliminates front-side shading and maximises use of the encapsulation area by combining precision overlap soldering with busbars hidden and relocated to the rear. The result: active cell area increases by approximately 1.7% within the same module footprint, translating directly into higher power output.
AIKO – INFINITE modules set new standards
The technology is already being deployed at scale. Since December of last year, AIKO has delivered over 100 MW of these high-efficiency modules, with installations across multiple commercial and industrial projects. Applications span several provinces in China – including Guangdong, Sichuan, Jiangxi and Chongqing, as well as overseas markets such as Thailand. These deployments confirm stable performance across a range of operating and climate conditions.
Separately, AIKO has launched two cell technology upgrade projects, converting PERC capacity at its Yiwu facility into 5 GW of ABC capacity and upgrading part of its TOPCon capacity at its Chuzhou facility into 6 GW of ABC capacity. (hcn)
