PERC battery technology has topped the mainstream high-efficiency technology list in the photovoltaic industry. In the past two years, Solarwit data shows that the total capacity of a single crystal PERC battery exceeded 80GW at the end of 2018 and will be loose to 100GW in 2019.
With the increasing effectiveness of PERC battery technology, coupled with the increasing market demand for lower-level capital and higher conversion efficiency, and the pressure of average prices from Escort, the industry urgently needs a new and efficient technology to lead battery conversion efficiency to another stage. And alien technology is becoming the target of competition among many companies such as Chengneng Technology, Oriental Risen, Shanmei International, Jingshi, and China Intelligent Power.

Incoming: The total investment exceeds 40 billion yuan to compete for the “cake”
PVs have discovered that the domestic Sugar daddy More than 10 companies have participated in the research and development and production of the warm and cool Xiaotianwen battery, with a total planned production capacity exceeding 20GW.
As one of the “breakers” in the alien sector, Xingneng Technology has achieved trial investment as early as 2017. It has an existing production capacity of 100MW, a maximum efficiency of heterogeneous battery capacity of 23.85%, and an average yield of 98.29%. The planned production capacity in the future is 1GW, and the equipment is being purchased.
In May 2018, Tongwei Co., Ltd. announced that it would cooperate with the Shanghai Microsystems and Information Technology Research Institute of the Chinese Academy of Sciences and the unlimited responsibility company of Sanyi Capital Holdings to cooperate in the construction of a 2GW heterogeneous solar battery capacity project. The first ultra-efficient and unusual-quality battery cell has been successfully upgraded to the lower line in June 2019, with the conversion effect of the battery cell reaching 23%. The advancement of Sanmao Capital as a participant means that the country is optimistic about differentiated technology.
On August 19, 2019, the annual production of 2.5GW high-efficiency heterogeneous battery and component production project of Oriental Risheng was officially launched. The project plans to produce adult production capabilities of 2.5GW battery sheets and 2.5GW components. The project is expected to be completed in 2021.
In addition, Shanmei International has recently announced the construction of a 10GW heterogeneous battery production line with jingshi;Rainbow Group and Aikang Technology will also invest in the construction of 2GW and 5GW of different types.

International heterogeneous battery capacity (departmental enterprises)
Odds: the highest quantity and efficiency, the shortest production process, and the best battery function
Many companies are competing to deploy heterogeneous components first, not to serve as “a savvy”, but to do it smoothly.
“The abnormal bonding battery has been industrialized for nearly 10 years, and the current level of abnormal bonding technology has become much more mature than in 2011. Because of this, many photovoltaic companies and capital parties have set their sights on abnormal bonding.” Xu Xin, deputy general manager of China Intelligent Power, told photovoltaics that the killing and production of PERC pricesSugar daddy‘s ability to release large quantities also provides growth opportunities for different quality batteries. The next growth point is the most advantageous thing about different quality batteries.
“Aliphatic battery is the most popular post-PERC high-efficiency technology recognized in the industry. It is important to have the characteristics of the highest production efficiency, the shortest production process and the best battery function.” Song Yifeng, senior manager of Oriental Risen Products Management, explained in detail that for the current mainstream high-efficiency battery technology, 23% of the volume is a visible mass-producing bottle. The current average efficiency of heterogeneous battery is over 23%, with the highest efficiency of the production line even reaching 24%. In the future, there will be no hope of 25%. At the same time, the entire production process of a heterogeneous battery requires only four production cycles, with a maximum working temperature of no more than 200℃. It can use 130μm or even thinner silicon wafers, which can reduce equipment and data.Hilippines-sugar.net/”>Sugar daddyThis space is large and not Escort manila will be the most cost-effective.
Based on the characteristics of no B-O light decay, no LeTID, lower temperature coefficient (based on the basis of half the amount of crystalline silicon homogeneous junction batteries), high double-sided ratio, low-light response, and other advantages, the abnormal-quality junction batteries can achieve higher power generation and lower LCOE. Song Yisheng goes to the next level According to a step, “According to the actual measurement data, in the application of PERC battery components and heterogeneous battery components, the power generation of heterogeneous double-sided components is 20-30% higher than that of high-efficiency single crystal PERC single-sided components, and 10% higher than that of high-efficiency single crystal PERC double-sided components. The LCOE brought by this is more than that of PERC double-sided batteriesSugar baby components should be 7% lower. As the market adds daily to LCOE, the advantages of the unusually high-quality battery components will double. ”
In August 2019, the news that Oriental RisenSugar daddy invested 3.3 billion yuan to build a new 2.5GW high-efficiency heterogeneous battery and component project was launched to attract attention from the industry, which also shows Oriental Risen’s ambitions in the heterogeneous field. Song Yifeng said: “The new project is built in stages and is expected to be completed by the end of 2021. To meet market demand, Oriental Rising’s first period’s unusually high-quality battery assembly products will be launched into the market at the fastest rate. High-end markets, areas with higher BOS and software costs, as well as areas with relatively poorer environmental conditions, will be the target markets of Oriental’s daily rising product. With the continuous expansion of production scale of different battery components and the continuous landing of capital, it will replace PERC in the future. escort Enter the main battlefield where photovoltaic applications are widely used. ”
Yang Liyou, general manager of Xinneng Technology, also held the same view. He believed that the product cost, performance ratio, effectiveness space, and labor.From the perspective of complex level, the mainstream high-efficiency technology after single crystal PERC is a different-quality conjunction technology. Yang Liyou introduced to photovoltaics that the average efficiency of the extraordinary bonded batteries of Xinneng Technology is 23.85% and the highest efficiency is 24.73%. Through third-party testing, the dual-sided ratio of heterogeneous components reached 93%, and the front power of 72 components without large silicon wafers, half-piece and other sieve technology reached 406.6W. “Today, the important sales of different types of components are in China and Japan. Japan (JapanSugar daddy) is a relatively mature market and is very acknowledged for efficient and ultra-efficient products.”
For the increasing number of enterprises entering the military’s different types of different types of enterprises, all the companies visited have shown that one is Escort On the one hand, the technical wall-reinforcement of manila has been fundamentally broken. On the other hand, the abnormal battery is moving from the industry to the rapid movement of enterprises. The slowly formed standard effect will help the rapid decline of capital and will be more conducive to the rapid decline of the economy.
Door points: The cost is higher, the scale is not large, and the equipment is more difficult to be compatible. However, the watch is like the two sides of the hard currency, and there are still doors that need to be passed by behind the different-quality battery red fire.
“One of the important obstacles to promoting heterogeneous bonding technology is the priceSugar baby.” Yang Liyou said that today, the heterogeneous bonding battery is still short and very high. It has a relatively small output and a relatively high cost. It has not yet competed directly in the market. “When there are several teachers in the industry. When GW production lines, if the price of a different battery product can reach no more than 15% of a single crystal PERC product, the different battery product will Manila escort will be very popular. “< TC:
