On August 12, the CCTV news channel "Chao Wen Tianxia" broadcast a special report "behind the new track behind the" new three kinds "and" behind the best-selling "photovoltaic products overseas", focusing on the story behind Chint's new energy photovoltaic modules leading the market demand. In the first half of this year, China's total exports of photovoltaic products reached 28.92 billion billion US dollars, an increase of 11.6 per cent. In this context, Chint Xinneng continued to increase R & D investment through the continuous introduction of innovative products. In the first half of the year, the growth rate of export volume and shipment volume exceeded 100.

Aim at "double carbon" target to run "green" track

In recent years, under the goal of "double carbon" in China, the photovoltaic new energy industry has become an inevitable trend of sustainable development, and solar cells have also become the "new three kinds" of foreign trade exports ". As the largest application market of photovoltaic, China is also the largest manufacturing base in the world, and it is an important wind vane for the future development of photovoltaic.

As the basic support of photovoltaic new energy industry, photovoltaic module technology ushered in a new period of strategic opportunities. As the p-type battery is close to the theoretical efficiency limit, TOPCon with high efficiency and reliability is the technical route choice for rapid industrialization, and it is also a cost-effective development route, and has achieved good results in practical applications. With the further development of technology and cost reduction, TOPCon technology is expected to play a more important role in the photovoltaic field, promote the development of the photovoltaic industry, and gradually become the choice of large-scale photovoltaic power generation projects.

Chint Xinneng has entered the photovoltaic field since 2006. It has a very deep accumulation and precipitation in component manufacturing and quality control. It is one of the earliest enterprises in the industry to realize mass production of N-type TOPCon components. According to CCTV reports, Chint Xinneng's N-type TOPCon all-black component, which was the first to be introduced in the industry, uses the latest design technology and can be perfectly integrated with the house body after installation, perfectly combining TOPCon's high power, high efficiency and "high color value". Once introduced, it will sell well in overseas markets such as Europe and Japan and become "explosions".

According to data from the Ministry of Industry and Information Technology, in the first half of this year, my country's photovoltaic industry generally maintained a steady and positive development trend, and the output of major links in the industrial chain achieved rapid growth. In the component sector, the national export of crystalline silicon components increased by 37.3 year-on-year, and the export of Zhengtai new energy components increased by more than 100 year-on-year.

N-type TOPCon leads the track in multi-dimensional widening of the "moat"

Since last year, n-type technology accelerated iteration, TOPCon technology with its high conversion efficiency, relatively mature equipment and technology, high mass production cost-effective, in the n-type route to the fore. According to statistics, the new TOPCon capacity will exceed 400GW in 2023, and the TOPCon output will be about 100GW in 2023, accounting for 20%-30% of the total battery output, becoming the current cost-effective technical route.

As the leader of n-type TOPCon, chint new energy will start research and development in 2020 and officially put into mass production n-type TOPCon batteries and components in August 2022. At present, Zhengtai Xinneng has landed in Zhejiang Haining, Jiangsu Yancheng, Gansu Jiuquan, Jilin Songyuan, Thailand and other eight intelligent manufacturing bases, TOPCon production capacity ranks second in the world. It is expected that by the end of this year, the n-type TOPCon capacity will reach 43GW, accounting for more than 81% of the total capacity. Compared with the previous p-type cell technology, this new n-type TOPCon technology improves the photoelectric conversion efficiency of photovoltaic cells by more than 2%. Xu Weizhi, chief technology officer of Chint Xinneng, pointed out, "Although this absolute number is small, in the photovoltaic industry, mass production of photoelectric conversion efficiency is the key to competition, even if it can achieve a 0.1 percent improvement in photoelectric conversion efficiency is a great progress."

During this year's SNEC exhibition in Shanghai, chint new energy released ASTRO N7 module. this series adopts n-type TOPCon 3.0 battery independently developed by chint new energy, superimposes SMBB technology, and introduces rectangular silicon wafer and gap reflective film technology. the module efficiency can reach up to 22.7 +, the power can reach 615W, and has the core advantages of high power, high efficiency, high reliability, high single watt power generation and high cost performance, with its excellent and reliable power generation performance and product quality, it has been unanimously recognized by TÜV Rheinland, UL, PVEL and other third-party organizations.

Empowering "Carbon" Future to Build a "Strong Engine" for Sustainable Development"

With the rapid advancement of the TOPCon 3.0 process route, the average efficiency of the battery mass production of Chint's new energy TOPCon has achieved a breakthrough of 25.6, opening up an "acceleration" in the TOPCon technology and capacity layout ". This year, in terms of production capacity layout, all the new production capacity of Zhengtai Xinneng adopts TOPCon battery technology, and has successively realized the expansion and new landing of TOPCon production capacity in Yancheng Base Phase II and Haining Base Phase IV, leading the TOPCon production capacity industry.

According to data from the National Energy Administration, my country's solar energy installed capacity increased by 78.42 million kilowatts from January to June this year. As of the end of June, the cumulative installed capacity was 0.47 billion kilowatts, officially becoming my country's second largest power installation, second only to coal power. Since the "14th Five-Year Plan", new energy represented by photovoltaics has entered a new stage of large-scale, market-oriented, high-level, and high-quality development. In order to promote the sustainable and healthy development of the industry, the National Energy Administration has continuously improved industry policies and optimized the development environment.

"At present, photovoltaic has entered an era of affordable power generation, and with the technological innovation in the past two years, the direct power generation cost of photovoltaic is cheaper than that of thermal power in most places, so this also makes our clean energy not only green and environmentally friendly, but also cost Competitiveness is also better." Lu Chuan, director of Chint Group, chairman and president of Chint New Energy, and chairman of Chint Xineng, said that thanks to the country's long-term policy support, a series of supports have been formed, making photovoltaic products not only have great application scenarios in China, but also in the world. It is also the product with the strongest demand and the strongest competitiveness.

In the future, Chint New Energy will continue to be committed to the innovative development of the photovoltaic new energy industry, continue to promote the green and low-carbon transformation of energy, deeply integrate into the new energy industry chain, and provide reliable and efficient clean energy solutions for more regions. to help the realization of the global carbon neutral goal.
