JinkoSolar: The secret to "leading the way" In Shanghai SNEC exhibition in May, JinkoSolar is undoubtedly one of the most shining brands. As a highly innovative photovoltaic company in the world, JinkoSolar shines in Shanghai with Tiger Neo series of high-efficiency modules, Jinko Crystal BIPV series products and intelligent solar storage systems. Not only that, during SNEC, JinkoSolar also announced a piece of information to build the world's largest N-type integrated manufacturing base of 56GW in Shanxi. Qian Jing, vice president of JinkoSolar, and Zhou Chaojie, director of energy storage product manager, explained JinkoSolar's recent industry and product trends in detail at the media meeting, and disclosed the details of this integrated manufacturing base. Leading photovoltaics for many years As a global leader in photovoltaics, as of the first quarter of 2023, JinkoSolar's cumulative shipments will exceed 150GW, ranking first in the global market, and it is also the first photovoltaic company in the industry to break through the milestone of 150GW shipments. At SNEC in 2023, JinkoSolar exhibited a total of five N-type module products, which fit the characteristics of the global household roof market and customer preferences in different regions, and adapt to multiple scenarios. Currently, they have been used in many ground power station projects and Distributed projects. The new generation of Tiger Neo series 182N-72 modules has a maximum power of 620W and a power generation efficiency of over 23%. The first-year attenuation, linear attenuation and temperature coefficient have been optimized in all aspects. It is expected to achieve mass production in Q1 of 2024. Qian Jing said at the media meeting: "In 2022, PERC has reached a growth stagnation period. With the strong growth of N-type demand and the accelerated expansion of N-type production in the industry, the N/P iteration speed will be faster than expected. As N-type JinkoSolar, the leader in N-type technology, will successfully mass-produce N-type technology products in 2022, and create excellent output and yield performance." JinkoSolar's self-developed N-type modules have broken the conversion efficiency record 22 times. The efficiency of the battery laboratory has reached 26.40%, and the mass production efficiency has exceeded 25.40%. Qian Jing said: "Our goal is to increase the mass production efficiency of TOPCon cells to 25.8% by the end of the year, which is a very leading level in the industry. Not only is the efficiency excellent, the high-efficiency N-type battery independently developed by Jinko has the advantages of "three highs and four lows": high efficiency, high power generation, high bifaciality; low attenuation, low temperature coefficient, low BOS, and low LOCE. In the application of N-type, Jinko has conducted a lot of experiments, combined with the power generation data of the client, it fully supports the power generation gain of at least 3% for N-type modules unde...

01. Diodes (1) Secret love is like a root diode, which always flows in one direction. Unless you are lucky and the diode breaks down in the reverse direction when you confess your love, you will continue to pay for nothing in return. Don't complain, who told you to choose the diode. (2) Betrayal in love is like the diode used to eliminate crossover distortion. When you first knew it, you couldn’t understand why that person robbed your lover, but later you realized that AC and DC are different. Yes, so, no matter men or women, before you get married, don't introduce the person you want to entrust your whole life to your best buddies, because often in the end, the problem lies here. 02. PN conclusion (1) Life is like a PN junction, no matter how it is made, there will be capacitance effects, and life will also have ups and downs. You hope that your life goes well, your love will always be sweet, and your marriage will be happy. Sorry, this is the same as eliminating PN junction capacitance. It is a worldwide problem, and of course we need to discover and explore. (2) Love is the PN knot that connects men and women. The teacher said that the PN knot has changed the world. Similarly, love also creates its miracles in this world. Love is a product of civilization, and so is the PN junction. Love needs a man and a woman, and the PN junction also needs two different semiconductors. Human beings cannot live without love, just like this era cannot live without PN junctions. PN junctions dominate the electronic world, and love dominates the history of our civilization.

SNEC site Mingguan n-type battery packaging overall solution, leading the upgrade of component packaging technology From May 24th to 26th, the world's most influential photovoltaic event - SNEC Photovoltaic Exhibition was held in Shanghai. At the scene, International Energy Network visited Mingguan New Materials. 2023 is the year when n-type technology will be fully scaled up. Enterprises have launched n-type products one after another, and hundreds of gigawatts of production capacity are under construction. The entire photovoltaic industry chain is ready for upstream silicon materials, silicon wafers, batteries, modules, and even backplanes, adhesive films, and silver pastes. China's photovoltaic industry is moving towards the n-type era in an all-round way. Then, why does China’s photovoltaic industry rapidly carry out technological iterations, what technical pain points still exist in the n-type era, and how companies face various impacts brought about by technological iterations? I met the relevant person in charge of Mingguan New Materials and listened to him reveal the answers to the above questions. In the n-type era, technology iterations are not limited to batteries The photovoltaic industry is a complete industrial chain. The emergence, development, and further advancement of any technology into the mainstream technology of the industry requires the cooperation of the upstream and downstream of the industrial chain. At the same time, the photovoltaic industry is a very fine-grained industry. Technology upgrades and then technical iterations are completed through bit by bit technological progress, and the process from quantitative change to qualitative change is completed. Just like the current industry hotspot - n-type technology, many people may turn their attention to the field of batteries and modules, focusing on the conversion efficiency of TOPCon or HJT batteries and modules, while ignoring that the improvement of battery and module efficiency is only the final result . In this process, silver paste, adhesive film, and backplane have also made important contributions, and technology upgrades and iterations are also required in the n-type era. According to the person in charge of Mingguan, although the n-type battery technology has many advantages such as high conversion efficiency, high bifaciality, low attenuation, and low temperature coefficient, the special structure of the n-type battery has great impact on the anti-PID performance of packaging materials, Corrosion resistance, water resistance, adhesion and other aspects have more stringent requirements. The packaging materials used in the past for p-type components are not enough to meet the needs of the n-type era. In order to shift the photovoltaic cell module technology from p-type to n-type with higher efficiency, it is necessary to solve the problem of packaging materials, and to have a packaging solution suitable for n-type cell modules. This is a real problem facing th...
