Today it's a little cold, and the warmth still lingers

On December 15th, Shenzhen Han's Photovoltaic Equipment Co., Ltd. (referred to as Han's Photovoltaic) signed a strategic cooperation framework agreement for the photovoltaic industry with Zhejiang Taiqu New Energy Co., Ltd. and the People's Government of Xingwen County, Sichuan Province at the Han's Laser Global Intelligent Manufacturing Center. This signing signifies that the three parties will engage in comprehensive and in-depth cooperation in multiple fields such as advanced photovoltaic technology, photovoltaic industry research and development, and photovoltaic industry cultivation, marking a new chapter in the comprehensive and deepening strategic partnership between the three parties.

Focus on hot topics for 3 minutes to learn about perovskite solar cells. Perovskite solar cells use organic-inorganic hybrid metal halides with perovskite crystal structure as the absorbing layer. Perovskite materials have better light absorption and adjustable band gaps, which have two core advantages compared to crystalline silicon batteries: higher theoretical conversion efficiency and lower production costs. Efficiency enhancement: At the theoretical limit, the maximum conversion efficiency of crystalline silicon solar cells, PERC monocrystalline silicon cells, HJT cells, and TOPCon cells is 29.40%, 24.50%, 27.50%, and 28.70%. Theoretical maximum conversion efficiency of single junction perovskite batteries

//The 5th China International Photovoltaic Industry Summit Forum was held grandly from August 25th to 27th, 2022 at the Tongwei International Center in Chengdu. At the meeting, Da Zu Photovoltaic Equipment was successfully selected as one of the top 100 Chinese photovoltaic brands in 2022 with a brand value of 20.588 billion yuan, thanks to its product strength and professional services! On the afternoon of the 25th, the "Photovoltaic Innovation Technology Sub Forum" was officially launched to explore new paths and look forward to a new future. Representatives from enterprises in the photovoltaic industry shared themes on hot topics and deeply discussed and exchanged new technologies and achievements in various links of the photovoltaic industry chain. In the era of rapid development of the photovoltaic industry and affordable internet access, ensuring

Although the mass production efficiency of PERC batteries has continued to increase by 0.4% to 0.5% annually in recent years, it is also approaching its theoretical efficiency limit. Solar cell technology is facing a new technological turning point. Who can take over the role of PERC? Currently, the focus of industry discussions is mainly on TOPCon and HJT technologies. In the long run, it is not yet certain who can lead the industry between these two. However, in the short term, TOPCon can be well compatible with the huge existing PERC production capacity, effectively extending the lifespan of existing PERC production lines while upgrading them, improving efficiency, and reducing PERC production

At the 19th China Photovoltaic Academic Conference (CPVC-19), Wang Junchao, CTO of Dahua Photovoltaic, delivered a keynote speech on "The Important Role of Equipment in Improving the Efficiency of Photovoltaic Cells", introducing the application of laser technology in new solar cell technologies in the future. He proposed that "equipment is the embodiment and materialization of advanced processes", and that good equipment is an important support for the industry to enhance market competitiveness and sustainable development capabilities.
