AIKO Solar’s Product and Solution Manager Mohammad Alshrouf called all back contact (ABC) technology that the manufacturer adheres to as the ultimate route to achieve the ultimate efficiency for monocrystalline silicon cells. Tandem BC cells are the development direction for AIKO in the future, he said while speaking on day 4 of the 4-day TaiyangNews High Efficiency Solar Technologies 2024 conference.
The absence of grid lines on the front of the cell in a BC structure, with full passivation at the back, ensures no shading loss on the front and also a higher cell efficiency. Thanks to its low temperature coefficient of -0.26%/°C as against -0.29%/°C for TOPCon, it generates 6% to 10% higher power than a TOPCon module.
Alshrouf stressed that AIKO’s ABC modules have 1.2% lower degradation in 25 years and 1.5% less in 30 years vis-à-vis TOPCon. These are also attractive an option for the residential segment.
For its upcoming INFINITE solar modules under ABC Gen III, AIKO is undertaking more technical measures to improve the module power as well as efficiency. One of these features is the decreased non-cell area by increasing the cell coverage ratio, which alone is likely to increase the output by 8 W. Eliminating the gap between cells will also add 5 W. Getting rid of the busbars will also reduce electrical losses. Overall, these measures are likely to improve the output by 15 W.
In 2025, AIKO will run GEN II and GEN III lines as standard products. GEN III can be expected to be rolled out by the middle of next year.
