BC Battery Year End 'Big Shot'! The pattern of photovoltaic cell technology has become apparent

At the end of the year, BC Battery announced the launch of its latest photovoltaic cell technology, which undoubtedly dropped a bombshell in the photovoltaic cell market. As an important promoter of photovoltaic technology, the action of BC cells has not only attracted widespread attention in the market, but also filled people with expectations for the future development of photovoltaic cell technology.

    Photovoltaic cell technology, as a key link in solar energy utilization, has always been a focus of attention in the industry.

In recent years, with the continuous breakthroughs in technology and intensified market competition, the pattern of

photovoltaic cell technology has gradually emerged. BC cells, as a leader among them, have occupied an important position

in the photovoltaic cell market with their profound technological accumulation and continuous innovative spirit.

    The year-end "amplification recruitment" of BC cells is the latest achievement of its continuous innovation and exploration

in the field of photovoltaic cell technology. It is understood that this new photovoltaic cell technology adopts advanced

materials and processes, significantly improving the efficiency and stability of photovoltaic conversion, thereby reducing the

cost and energy consumption of photovoltaic systems. This breakthrough is expected to promote the popularization and

application of photovoltaic power generation, further changing humanity's dependence on traditional energy sources.

    A spokesperson from a photovoltaic module company told Caixin that the current technology roadmap of mainstream

module companies is basically fixed, but they generally maintain their attention to the research and development of other

technologies. Even top companies that bet on TOPCon may consider switching to other technology capacity in the future

when their technology roadmap matures, such as when the cost of heterojunctions can significantly decrease. Especially

next year, it is not ruled out that component companies with a single technology roadmap will develop multiple technologies

to meet different market demands.

    BCization may be one of the important upgrade directions in the short to medium term in the future. In fact, prior to

September this year, the technological competition in the N-type era mainly focused on TOPCon and heterojunctions. As a

platform based technology, BC battery (full name BackContact, back contact battery technology) was the only leading

enterprise to test the waters, with only Aixu Co., Ltd. With Longi Green Energy announcing its bet on BC batteries, this

technology has once again received high attention.

    While promoting industrialization, laboratory efficiency is constantly innovating. On December 19th, according to the

authoritative certification report from the Hamelin Institute of Solar Energy (ISFH) in Germany, the back contact crystalline

silicon heterojunction solar cell (HBC) independently developed by Longi Green Energy adopts HJT+BC technology and uses

a fully laser patterned mass production process to achieve a cell conversion efficiency of 27.09%, setting a new world record

for the efficiency of single crystal silicon solar cells.

     We look forward to BC cells continuing to maintain their leading position in the field of photovoltaic cell technology in

the future, continuously promoting technological progress and innovation, and making greater contributions to the

sustainable development and environmental protection of human society. At the same time, we also hope that more

enterprises and research institutions can join this ranks, jointly promote the development of photovoltaic cell technology,

and contribute to building a better future.
