On November 2-4, the 19th three-day CSPV "China Solar Grade Silicon and Photovoltaic Power Generation Seminar" was officially held in Xi'an. The conference gathered photovoltaic industry experts in batteries, modules, equipment and materials and technology giants of various enterprises, and shared hundreds of reports, which was unprecedented.

Niu, chairman of Mr Wang niu and deputy general manager Mr Yong-gang wu was also invited to attend the event, they brought the direct mulching technology (IFC) influence on component encapsulation and the IFC technology and industrialization solutions " two reports, IFC technology is 0BB production better solution for further analysis.

1. 0BB + IFC cost reduction and efficiency increase, mining space is large

 First of all, Wang Dong of Niu told in the report that 0BB battery equipped with IFC technology can not only improve the efficiency of traditional battery, but also improve the efficiency of BC battery. The no main grid BC battery has no main grid line, and the end of the original main grid and the fine grid can extend the length, which can improve the current collection ability of the fine grid. In addition, the 0BB battery equipped with IFC technology can also improve the ability of the components to resist hidden crack.

In terms of cost reduction, in addition to reducing the cost through less silver and less silicon, because IFC technology is low temperature connection, it can also effectively solve the problem of high temperature oxidation of copper and easy oxidation failure of copper plating gate wire, so the battery can use lower cost electrode materials.

In addition, there is still a lot of space in the cost reduction of the membrane material, which requires the joint exploration of materials, components and equipment manufacturers.

2. IFC technology is a better solution to achieve 0BB mass production

In the "N-type TOPCon Battery Component Technology and Equipment Materials" sub-conference, Mr.Wu made an in-depth comparison of several 0BB connection solutions on the market, IFC technology can not increase the cost, mass production is easy to achieve, more adapt to the chip, is to achieve 0BB better solution.
