As the world enters the XBC era, the market is getting ready with relevant products and equipment technologies. On Day 4 of the 4-day TaiyangNews High Efficiency Solar Technologies 2024 Conference in December 2024, DR Laser’s Vice President, Sales & Marketing Ben Lee presented the company’s ‘breakthrough’ Laser Integrated Bonding (LIB) technology for 0BB and XBC manufacturing.
In the journey to 0BB XBC manufacturing, the challenges relate to reliability, module power, manufacturing cost, and bifaciality. This is where LIB comes in. Lee defined LIB as an innovative laser soldering process specially developed for 0BB XBC PV modules. It enables ‘perfect bonding’ between solar cells and ribbons with a single laser process at the module scale, preventing micro-cracks and ensuring non-contact soldering.
Among its other benefits is higher bifaciality, which can increase by more than 10% than reference IR soldering. Further improvement is expected. LIB-backed 0BB can also bring down silver paste consumption by more than 20%, Lee claimed, referring to the results shared by 3 of its customers.
This technology can help reduce silver consumption to 80 ~ 90 mg and enhance the bifaciality of XBC modules to 75%, potentially to 80% or even higher, summed up Lee.
