elease reserved space, Yingfa to create N - type battery development new speed

Pv technology iteration is gaining momentum, with new and old players gathering in N-type battery and module production. As early as a few years ago in the planning, has reserved the development of N-type battery space.

"Only make batteries, make better batteries" is the industrial purpose of YingFaereng. In this International solar photovoltaic and Smart Energy Exhibition (SNEC), Yingfa Rui with its N-type TOPCon16BB battery and 182 PERC 9BB, 10BB, 11BB battery appeared, won the attention of customers at home and abroad.

Reporter interview with the sales director of Yingfa Rui Energy Li Juan learned that the new TOPCon battery launched by Yingfa Rui Energy is Topcon 2.0+ route, is the combination of high energy and low damage laser SE doping and ultra-thin polysilicon technology, At the same time, superposition alkali throwing high back reverse technology, non-coated single-side ALD technology, multi-layer anti-reverse film passivation technology and based on advanced industry 5.0 workshop intelligent management platform, greatly improve the efficiency of the battery, conversion efficiency has reached 25.45%, the current yield of 92%, the future is expected to break 97%.

Technology and production capacity continue to be upgraded

"2022 will be a year of steady development of Yingfa's photovoltaic cell sector, and 2023 will be a year of rapid expansion of Yingfa's production capacity." "Yingfa wrote on its official Weibo account. In January this year, Yingfa has completed the whole TOPCon pilot line, which includes the machinery and equipment of the market mainstream LPCVD and PE-poly process.

The production efficiency of the pilot line reached the standard in only one month, which not only demonstrated the "speed of British hair", but also fired the first shot of British hair battery technology reform. Up to now, the two routes have been completed, and the efficiency and yield are on the climb.

It is reported that at present, the British Fa has Anhui Long (Yingfa Rui Neng, Yingfa Desheng), Sichuan Yibin (Yingfa Deyao) two battery production bases. In Yibin 24GW project invested by Yingfa, the first phase of 12GW PERC battery has been completed and put into operation. The second phase is 12GW N-type TOPCon battery, which has been capped on April 18th this year and is expected to be put into operation in August this year.

On May 11th, Yibin Yingfadeyao Phase 4 officially signed a contract on 16GW high efficiency crystalline silicon solar cells and 20GW Czoellar monocrystalline silicon rod projects. "At present, the market is in the stage of technological iteration, and photovoltaic cells are often limited by silicon wafer production capacity. In order to break the supply limit and give play to the company's technical advantages in the battery side, we choose to do the silicon rod project." "Li explained.

In terms of Yingfa's overall plan for batteries, Li Juan said, "The planned total capacity of the company's batteries in 2023 is 30GW, and the expected battery shipment by the end of this year is 25GW. The total capacity of the battery plate in the future is planned to be 50GW, of which the capacity of N-type battery is planned to be 28GW."

With the advent of the N-type era, Yingfa chooses to continuously upgrade on the basis of TOPCon to improve conversion efficiency. To be specific, at present, the original technology has been superimposed on SE technology, and the new technology will be superimposed in the future, so as to constantly approach TOPCon's ultimate efficiency. For example, the double-sided POLY technology, which has been discussed a lot at present, will be superimposed on more efficient IBC process and reserve the heterojunction technology in the future. Be prepared for new technologies in the future.

Focus on battery production

Different from the industry trend -- integrated layout, Yingfei Rui Neng clearly chooses only to make cells, and takes making better cells as its purpose. When talking about why the company makes such a choice, Li Juan said: "From the industry as a whole, improving the efficiency of cells is the core direction of technology innovation in the photovoltaic industry, and cells are also an important core link of the whole photovoltaic industry chain; At the same time, the battery manufacturing technology is more demanding, the process is more complex, and requires continuous technical investment, so we choose to focus on battery production."

Yingfa is determined to be a core participant in the development of photovoltaic industry, and is committed to producing better battery products to give back to customers and the public. According to the reporter, in the field of battery, the UK has made breakthrough achievements, the company's independent research and development of "automated silicon wafer transportation device" technology, greatly improve the production efficiency, is at the same time to declare utility model and invention patent, the utility model patent has been authorized, invention patent into the actual examination stage.

In terms of production and construction of the enterprise, Yibin Yingfadeyao Phase I A1 workshop has become the world's largest single unit area, the largest single day volume in a single plane. Yingfa has also built a provincial-level enterprise technology trust platform, which has won the honorary title of "Little Giant" enterprise and the national high-tech enterprise certification. And on the road to focus on battery development, Yingfa is also expected to enter the stock market.

Li Juan said that the company will complete the main board of the Shanghai Stock Exchange listing declaration this year. After landing in the capital market, Yingfa will continue to deepen the field of photovoltaic, and will grasp the opportunities of The Times, look around the world, looking for other areas rich in green electricity resources and broad market prospects to build a larger scale of intelligent manufacturing base, to achieve a qualitative leap in production capacity.

Under the guidance of clear enterprise planning, Yingfa will continue to advance on the road of refining, strengthening and finally enlarging battery products with the "Yingfa speed".
