The discussion on next-generation technology has been particularly hot this year. From the reporter’s perspective, this anxiety is complete and complete, so we can understand that no one is willing to take the initiative to make single crystals before 2016 or poly crystals after 2018. In this way, it seems too utilitarian. It is not as popular as the single crystal manufacturer before 2016, and there will be no current national prosperity in single crystals. The latest data shows that the proportion of single crystals in component exports in October reached a historical high of 75.5%.

At the same time, the expansion of each dragon in the single crystal field has not been relaxed. According to reporters, the global single crystal PERC production can reach 120GW. If all the development plans are only Song WeiSugar baby replied happily, “It’s okay, I’ll come back and have a look.” This number will be changed to 150GW when you are old. As for the situation of polycrystal manufacturers, it is important to be clear from a joke that reporters have heard recently: the most popular location in the industry is not Longi, which is cooking oil on high heat, nor Jinko, which is seeing the four-star best-selling goods, but Ates, which is also producing polycrystalline PERC. There are many sales staff of polycrystalline silicon manufacturers outside his home.

About the technical routes after single crystal PERC, there are actually many Sugar daddyPinay escortTwo years ago, the teacher had a certain common understanding: PERC is of course N type, and it is hard to say which type is N type. It actually looks like N-PERT, N-PERL, HJT/HIT, IBC… It looks like Sugar babyEach has its own advantages, and any of them can do it.

Until the rise of TOPCon’s exotic army in 2018, many manufacturers have emerged as renowned. This battery technology equipment derived from IBC can be upgraded to the existing P-PERC base, and the cost is expected to be greatly reduced. At the same time, the long-term research on the disparity has also been broken, and the capital market’s interest in HJT has also arisen.

At this point, HJT still has a complete dispute over the route of Sugar daddyTOPCon. The middle of this year, the reporter met several equipment manufacturers at a business meeting in Hangzhou. No matter what topics they talk about, they would finally find out: Do you think the next generation of technology is HJT or TOPCon?

At that time, the reporter was on the site of TOPCPinay escorton. The reporter’s final understanding of TOPCon came from a new dynamic founder, Teacher Liu Yong, who was still in charge of TOPCon technical attacks that were not optimistic about by the teachers. He told reporters that TOPCon is very compatible with today’s mass production technology, with potential effectiveness of 28.7% and closest to the theoretical limit of crystalline silicon solar battery of 29.43%. This is the space for the Master to think that the TOPCon battery is more mainstream, which has a further step-by-step conversion effect. In short, it is TOPManila escortCon battery can earn more effectiveness at a smaller cost. It is because of the great power, so that people can’t stand.

In the dream, the heroine has achieved good results in every topic, and Ye Qiu, who has the lowest performance, has the lowest performance

Domestic TOPCon BatteryIn terms of the market, the capacity has been less than a few: Zhonglai Co., Ltd.’s full-size N-type single-crystal double-sided calcified contact battery has achieved a effectiveness of 23.3%; Trina Solar’s R&D’s calcified contact battery has achieved a effectiveness of 2Sugar baby4.58%; Jingke Research’s large-scale TOPCon battery conversion efficiency reached 24.2%; Yingli’s Panda-TOPCon data reached 21.54% in January 2018.

The data obtained by reporters from a famous equipment manufacturer, as long as China, Tianhe, Linyang, Jinko and Yingli have practical production capabilities, they are not large, but are mostly experimental lines, with battery chips priced at around 1.45 yuan/W. Yingli will officially release the TOPCon battery at the age of time, and the actual situation is currently being kept secret, and a new force that is entrusted with high expectations has not been developed like the master is waiting. “Although the industrial modification is not large, you can upgrade from the existing single crystal PERC line to TOPCon by simply modifying and expanding the furnace and Sugar daddy tunneling, but it is so stable that there is no complete guarantee at present,” the manufacturer representative told reporters Sugar daddy.

Global HJT battery production capacity

Compared with TOPCon, HJT’s situation is much betterSugar daddy. Because of its relatively simple technology, strong ductility, and extreme conversion efficiency, 27.5% of Sugar baby‘s completeness is not less than TOPCon, HJT agility has attracted the attention of the capital market, with more than 20 companies having layouts, and each company’s scale is 100 MW.

Reporter survey, the actual capacity of HJT in ChinaSugar babyThe plan is about 1.6GW, the planned production capacity is 38GW, and the battery film price is about 1.5 yuan/W. The domestic production capacity is mainly concentrated in Japan (Japan). “This child!” The neighboring family was helplessly slammed, “Then go back, Xiaowa american, it must have an actual production capacity of 2.7GW, and the planning capacity is 3.6GW, and the production capacity is from Sugar daddy21.5%-23.5%, agility has become the bond of capital and “became a new story.”

But it is not impossible to see it, HJT has beenManila The chronic disease that escort cannot be solved: equipment cost remains high (about three times that of PERC equipment); technical requirements are strict; low-temperature assembly packaging technology demand. The master hopes that technical breakthroughs can significantly reduce equipment investment. After many companies have entered the layout, they have forced equipment manufacturers, especially domestic equipment manufacturers, to reform technology. “In 2-3 years, the company will be established. Baby‘s reserve capital has dropped by more than 50%,” a representative from a famous domestic equipment manufacturer revealed to reporters.

At this point, do you feel that TOPCon’s chances are bigger or bigger? However, recently, the Institute of Electrical Research Institute of China Academy of SciencesSugar daddySoul Battery Research OfficeSugar daddySoul Battery Research OfficeSugar daddy Director Wang Wenguan revealed a new view to the reporter. He believed that HJT and TOPCon are not short, which is completely opposite. Now Sugar Baby‘s research and expression, there is a different ability to do TOPCon in a different way, which can not only maintain the simple characteristics of HJT’s craftsmanship and realize the largest savings in equipment investment capital. Just as the results of the competition between single crystals and polycrystals will give birth to single crystals, in the future, HJT and TOPCon will have the same chance.

Technology will always bring us various capabilities, but no matter which choice Sugar baby, the reporter trusts that the N-type single crystal will definitely replace the current P-type PERC in the future. At most, there is no doubt about this, is it right?
