End of December 2017—On the eve of Zhonglai Co., Ltd.’s ten-year anniversary, Chairman Lin Jianwei published an article titled “Don’t remember the past, don’t miss the future, and the New Year flows in the water”, opening the article Lin Jianwei wrote, “I finally arrived in 2018, I was just ten years old, and I survived ”
From 2008 to 2018, in the past decade, photovoltaic industry has experienced the financial crisis, the double-revolution of photovoltaics in Europe and the United States, from a high-glow moment to a cold winter in the industry. Numerous companies have advanced and countless companies have joined, and many have joined, among which there are many superstar companies. It is not easy to survive after ten years of wind and rain. In 2019, what are the goals of the Chinese 10-year quibulation? Lin Jianwei’s final word is: to build a sustainable enterprise.
Departed from the “sub-corner” of the station
Before its establishment, Lin Jianwei was important in making polymer coatings and aluminum materials. In 2008, based on multi-party considerations, Lin Jianwei decided to enter the photovoltaic industry and worked hard to develop and manufacture photovoltaic backplanes. In this way, in the rented factory, only a dozen teams of people were established.
Before 2008, the backplane market was dominated by fluorocarbon backplane, and international manufacturers such as american DuPont and French Arcoma. It accounted for a large market share and even blocked the domestic market, with a very high price.
From 2008 to 2009, it took only two years to successfully implement technical breakthroughs, innovatively developed the FFC dual-surface coating series backplane products, and created a brand new backplane structure sequence. With the market response, Zhonglai accelerated the real guidance rate of important customers after product research and development. In 2014, it gained 94 million profits and won the market’s high recognition. In September 2014, China entered the Shenzhen Stock Exchange to establish its business board, becoming the first listed company in China to focus on photovoltaic backboards.
In October of the same year, Zhonglai released an upgraded version of FFC products and proposed a “non-fluorine-free” view. At that time, Lin Jianwei predicted that the market for “coated back panels is rising, and double-sided fluorine-containing back panels will become mainstream in the market in the future.” In 2016, after 8 years of hard work, Zhonglai photovoltaic back panels accounted for the global market.s-sugar.net/”>Pinay escort has risen to the first place in a rate of 2018. As of the end of 2018, the accumulated shipment of China FFC dual-surface coated backplanes has exceeded 200 million square meters, with more than 36GW of components, and end customers have filed 0 complaints; one is Manila escortThe cutting structure back panel ships more than 400 million square meters, with nearly 80GW power stations.
It won the world’s first place, and is intimate with the business philosophy of focusing on technology research and development and focusing on product quality. In Lin Jianwei’s view, “the combination of cost reduction and efficiency enhancement is the main driving force for enterprises to maintain market competitiveness. “For many years, China Sugar baby has been continuously carrying out technical innovations to promote the price of photovoltaic backplane products from more than 100 yuan per square meter to 12 yuan per square meter.
While reducing costs, the efficiency enhancement cycle has not fallen behind. Catching the trend of double-sided power generation, China Sugar is continuing to Sugar While promoting the efficiency and optimization of the original back membrane products, baby has developed TPT/TFB/FFC full series of unobstructed back membrane products and power gain net unobstructed back panel products. The aging function of this product is excellent, better than the aging function of the common white back panel; At the time, the light transmittance is >92%, which is different from the ultra-white pressure glass base and has no impact on the power generation basis. Single glass clear back panel double-sided components can effectively solve the pain points of double-sided components, such as burst, weight, non-respiratory properties, etc., and is the best packaging data for double-sided components.
Sugar daddyTuolu N-type dual-sided battery components
When an enterprise became the world’s number one in the backplane industry, what should we do in the future? This problem was once before Lin Jianwei. Photovoltaic backplane is ultimately a wheel, and each episode will be eliminated until the remaining 5 participants challenge five companiesManila escort The material in the chain, and Zhonglai is obviously not satisfied with only making side angles.
This time, Zhonglai turned his attention to the electricThe focus of the station – the battery component end. The N-type single crystal double-surface battery circuit is selected. It is clear that the N-type double-sided electric concept: Love life pool has five advantages: double-sided electric generation, low light response, low temperature coefficient, low task temperature, and high photo-induced decay. Not only can the power generation capacity be improved by 10% to 30%, but also the price of floor plates, engineering, building materials, and installation is also set, which can be a combination of cost reduction and efficiency improvement.
In September 2016, Taizhou Zhonglai Optoelectronics, a fully-owned subsidiary of Zhonglai Co., Ltd., had its first N-type single crystal double-sided battery that successfully defeated the lower line. The total investment of the N-type single crystal double-sided battery project is nearly 2 billion yuan, covering 14 efficient production lines and high-efficiency battery research and development centers with an investment of 100 million yuan. After the project was completed and achieved a helping hand. , can realize the production capacity of N-type single crystal double-plane battery with over 2GW. A new N-type single crystal double-faced component production capacity has been added, that is, the double-faced electric pool and component production capacity exceeds 3GW.
Under the continuous decline in photovoltaic replenishment, the advantages of double-sided power generation technology have become increasingly apparent. This has been seen in the third batch of runner bases.
Taking the National Electric Power Group Selection Type as an example, Sugar daddyAccording to the technical parameters of the divisional components in the runner project bidding stage, the National Electric Power Runner Project Package Tenders are all single crystal series, including P-type and N-type. Among them, the content of the double-sided double-glass component that has attracted attention reached 923.42MW, accounting for 75%.
Among the 10 photovoltaic application bases, 5 bases have selected N-type dual-surface power generation technology, and are from N-typeSugar daddyDouble-faced products are deeply involved in each base.
Photovoltaic industry is a technology that constantly changes new information and progress, and is constantly in the Sugar. Baby is studying and developing. At the end of 2018, China National Taiwan University reformed and upgraded the PERT production line to the calcified contact line. Dr. Liu Zhifeng, General Manager of China National Taiwan Optoelectronics, introduced that the N-type dual-surface calcified contact battery is easy to compatible with the existing n-PERT production line, which can improve the back of the PERC battery. baby significantly reduces the reconnection rate of the electrode contact area, and obtains higher Voc and other advantages. Zhonglai Co., Ltd.’s N-type dual-sided contact battery has a frontal efficacy of more than 22.5% and a backal efficacy of more than 19%. The output power of the 60-piece battery assembly can reach 330W on the front, and other backs can achieve a 10%-30% power gain. It can be said that it is an efficient person. The leader among runners.
Under the new policy in 2019, the station owner faced the decision of single crystal OR polycrystalline, focusing on initial investment capital or on electricity capital. Lin Jianwei decided on the N-type single crystal double-sided route, and he said, “For batteries, efficient is the purpose of development, and N-type double-sided single crystal is a big trend, and the trend has not been achieved.” The N-type dual-surface battery has higher power generation efficiency. In the distributed industrial and commercial projects, it can improve the application of roof resources. At this time, she should be at work instead of dragging her suitcase. In overseas markets such as Europe, South Korea, and Australia, NSugar baby are welcome to customers. ”
Lin Jianwei introduced that in the booming domestic market, N-type single crystal double-faced products face the lack of production capacity, and in the next few years, Zhonghai will continue to expand. “But Zhonghai’s expansion is TC:
