Top 5 photovoltaic PERC battery companies in China

Due to different technical routes, photovoltaic cells are mainly divided into P-type batteries and N-type batteries, and the technology of P-type batteries is more mature. At present, the mainstream products of mainstream top 10 photovoltaic battery companies in the world in the market are still P-type PERC batteries.

However, China has a lot of companies manufacturing photovoltaic PERC battery, but the question is “How can you pick the best company among these leading photovoltaic PERC battery companies in China?” To answer this questions, we have listed the top 5 photovoltaic PERC battery companies in China in this article, including Tongwei, LONGi, Jinko Solar, Trina Solar and JA SOLAR.

1. Top 5 photovoltaic PERC battery companies in China list

① Tongwei

Tongwei officially entered the field of photovoltaic cells in 2013. Tongwei is a leading silicon material company and a leading cell company in the photovoltaic industry chain. The company officially cut into the module side in 2022, and won more than 9GW of module orders that year, becoming a leader in photovoltaic integration.

Tongwei is an industry leader in battery technology. Tongwei's battery technology route is mainly P (PERC) type, and the production capacity and shipments of P-type batteries account for more than 95%. As the photoelectric conversion efficiency of P-type cells gradually approaches its maximum theoretical value.

Tongwei has also increased its layout on N-type cells. In terms of TOPCon, the company has adopted the self-developed 210 PECVD polysilicon deposition technology route. In terms of HJT, Tongwei currently has the highest research and development efficiency of HJT batteries reaching 25.67%. For other batteries, Tongwei has established an IBC battery test line.

② LONGi

As an established leading company in the photovoltaic industry, LONGi is a model of integrated photovoltaic development. Its core business includes silicon wafers, cells, modules, and power station operations. It is in the leading position in the industry in terms of production capacity and technology in the battery sector.

LONGi has achieved comprehensive leadership in various new high-efficiency battery technologies such as N-type TOPcon, P-type TOPcon, N-type HJT, P-type HJT and indium-free HJT. In November 2022, the conversion efficiency of the silicon heterojunction cell independently developed by LONGi will reach 26.81%, breaking the efficiency record of silicon solar cells that has been dusty for 5 years. At the same time, LONGi also mastered the HPBC battery technology, and released Hi-MO 6 in November last year.

The mass production efficiency of the standard version of the HPBC battery exceeded 25%, and the PRO version with hydrogen passivation technology superimposed had an efficiency of over 25.3%. This technology can greatly improve the light absorption and photoelectric conversion capabilities of the battery through the adjustment of the internal structure of the battery, and effectively increase the output power of the module.

③ Jinko Solar

Jinko Solar's main business includes research and development, production and sales of photovoltaic silicon wafers, cells and modules, as an integrated photovoltaic manufacturer. Jinko Solar's self-produced cells are mainly used in the company's module production, and because the capacity of cells is less than that of modules, the company will also purchase a large number of cells.

In terms of battery technology route, Jinko Solar not only has a large production capacity in PERC, but also takes an industry-leading position in N-type batteries. The large-area N-type TOPCon battery independently developed and designed by the company has achieved a conversion efficiency of 25.25% in laboratory research.

The company's TOPCon battery production line has been completed and put into production, with a production capacity of 35GW by the end of 2022. The average conversion efficiency of mass production reaches 24.2%, 21% higher than the industry standard, and higher than the PERC battery conversion efficiency, which has the basis to replace PERC batteries for industrial applications and drives the development of home energy storage. With its outstanding technical route, the yield rate of the company's TOPCon battery products is close to that of PERC battery products.

④ Trina Solar

Trina Solar is an integrated photovoltaic manufacturer. Its main business is photovoltaic modules, photovoltaic systems and smart energy, and its core product is photovoltaic modules.

However, Trina Solar has always had a layout for both the battery slice and the module. Almost all of its battery products are used to produce the company's module products, and even some of the battery products are purchased outsourced.

However, Trina Solar also occupies a relatively important position in the battery sector, and its battery production capacity and battery technology are also at the leading level in the industry. Trina Solar's battery production capacity is mainly based on PERC batteries, and it has been laying out N-type TOPCon batteries since 2015.

⑤ JA SOLAR

Since its establishment, JA SOLAR has been mainly engaged in the operation of silicon wafers, solar cells, photovoltaic modules and photovoltaic power station. Among them, photovoltaic modules are the company's core products, and the company's battery products are mainly for the production of modules, and rarely sold to the outside world. But JA SOLAR has a deep accumulation in the field of photovoltaic cells.

In terms of N-type battery layout, JA SOLAR's battery production capacity under construction adopts N-type battery technology. According to the company's plan, the company's N-type battery production capacity will exceed 40GW by the end of 2023.
