High-efficiency ABC INFINITE Modules by AIKO

AIKO has launched its upgraded n-type ABC (All Back Contact) ‘INFINITE’ modules at Intersolar Europe 2024. Modules in the product line, with enhancements in cell efficiency and light absorption area and featuring a seamless, integrated surface, boost maximum power output to 700Wp, with a deliverable efficiency exceeding 25%.

The INFINITE series represents a comprehensive breakthrough in technology and processes, from silicon wafers and cells to modules. By utilizing ultra-high resistance n-type silicon wafers and highly efficient ABC cell technology, combined with reliable 0BB (zero busbar) string soldering technology and innovative techniques including hidden busbar and precise stacking, the cell coverage rate is significantly improved. This results in a larger light absorption area and higher cell efficiency.

AIKO’s self-developed ultra-high resistance silicon wafers feature a doping concentration lower than that of traditional wafers, with a resistivity greater than 30Ω·cm, and a tenfold increase in minority carrier lifetime. This ensures low degradation and high-power generation throughout the product’s lifecycle, creating greater potential for ABC cell efficiency enhancement.

The non-cell area is approximately 6.5% of the module surface. Reducing this area can effectively enhance module power. In the INFINITE series, AIKO moves the string connectors to the back of the module, increasing the light absorption area on the front by 1.1%. The innovative insulating materials used address the reliability challenges of hidden string connectors. Additionally, AIKO’s newly developed ABC precise stacking process eliminates cell-cell gaps and increases the light absorption area by 0.5%. The stacking process and the natural compatibility of the ABC module’s linear soldering reduce stress and minimize the risk of micro-cracks, addressing the reliability issues of stacking technology.

“The launch of the INFINITE modules is another step by AIKO on the road to challenge the ultimate conversion efficiency of crystalline silicon cells. By making full use of sunlight in every scenario for more energy conversion, making each square of module more powerful, and maximizing power output per watt, we aim to provide higher-value products for multiple scenarios, including utility, C&I and residential,” AIKO chairman Chen Gang commented.

The “INFINITE” series cover utility, C&I, and residential scenarios. The power output of the 2382×1134mm module has increased from 655Wp to 680Wp, with an efficiency of 25.2%. The power output of the 2465×1134mm module is 700Wp. These highly efficient and high-performing ABC “INFINITE” modules are set to deliver unprecedented value and returns for all customers.
