Under the goal of “double carbon”, the clean energy industry represented by photovoltaic has become a strategic emerging industry with international competitive advantage in China.
Guangdong zhongkepurui Technology Co., Ltd. (hereinafter referred to as “zhongkepurui”), located in Songshan Lake International Innovation and entrepreneurship community, was incubated and established by the high-efficiency crystalline silicon battery team of Songshan Lake materials laboratory. Based on 12 years of research experience in the field of crystalline silicon Cecep Solar Energy Co.Ltd(000591) battery, aiming at the cost reduction, efficiency increase and rapid detection needs in the production of Cecep Solar Energy Co.Ltd(000591) battery, the enterprise has developed and produced a variety of additives in the wet process of battery flocking and back polishing and a series of fast large-area quantitative imaging equipment, so as to help the battery production upgrade and transform to intelligent manufacturing, Further enhance the competitiveness of China’s photovoltaic products and provide scientific and technological support for the realization of China’s clean energy strategy.
focus on photovoltaic field
adhere to the integrated development of basic and applied research
“What we are doing now is what we especially want to do over the years. Some of our new ideas eventually become products and are applied in the photovoltaic industry. Due to the institutional innovation of the Songshanhu material laboratory model factory team project, we have obtained such a golden opportunity to realize the original intention of the research: original process promotes industrial technological progress .” Du Xiaolong, chairman of zhongkepurui and head of high-efficiency crystalline silicon battery team, said.
High efficiency crystalline silicon battery team was originally E04 research group of Clean Energy Laboratory of Institute of high energy physics, Chinese Academy of Sciences. In 2009, the team began to intervene in the field of Cecep Solar Energy Co.Ltd(000591) battery from the research on silicon surface / Interface Engineering of poly focus crystalline silicon battery. During this period, most of China’s basic research was limited to mechanism research.
Du Xiaolong has been thinking about the differences in research between the two countries because of his experience in R & D in Japan. “Japan’s applied basic research is closely related to industry, because they have a strong industrial technology level, many industries are leading in the world, and there is a huge demand to maintain competitiveness through innovative processes. At the same time, China’s high-tech industry is still relatively backward, and basic research and applied research are seriously disconnected and not integrated.”
At that time, Du Xiaolong believed that after the gradual development of China’s high-tech industry, it will usher in the stage of independent innovation and improving competitiveness. Therefore, the team laid out early at the beginning of the research on the field of silicon Cecep Solar Energy Co.Ltd(000591) battery, made it clear that the research should be closely linked with the application, and moved from basic research to industrial application step by step.
With the gradual progress of research, China’s photovoltaic industry has also developed rapidly, from the initial purchase of foreign production technology to independent technology development and iteration. Based on the in-depth research accumulation in the silicon field in the past, in 2016, the team began to cooperate with the enterprise for the first time, extended the new process research from the laboratory to the enterprise, realized the transfer and transformation of process technology, and obtained a transfer fee of nearly 10 million yuan.
“There is a very consistent international understanding that the extreme change of environment and climate is due to the increase of carbon dioxide concentration in the air.” Du Xiaolong said that among non carbon energy sources, Cecep Solar Energy Co.Ltd(000591) has the most potential and can be used everywhere. Therefore, the development of photovoltaic industry plays an extremely important role in solving the global climate problem.
At the same time, energy determines the voice of the country. “China’s dependence on oil is as high as 70% and is controlled by others everywhere. The energy revolution has given China the opportunity to completely change its energy dilemma. As long as we go the right way, China’s energy prospect is bright.” Du Xiaolong pointed out that at present, China’s photovoltaic capacity accounts for 80% of the world. The team hopes to continuously improve the competitiveness of China’s photovoltaic products through independent innovation, so as to lead the development of photovoltaic industry technology.
innovative technology acceleration run
model factory + professional training to help entrepreneurship incubation
In 2018, Songshan Lake materials laboratory, which has four core sections: cutting-edge scientific research, public technology platform and large scientific devices, innovative model factory and Guangdong Hong Kong Macao cross science center, attracted teams to join.
“The innovative model factory project set up by Songshan Lake materials laboratory has implemented a series of innovations in management system, which provides a test field for a series of high-tech R & D in China.” Said Du Xiaolong. It is reported that Songshanhu materials laboratory organically combines basic research with industrial application, promotes technological upgrading by vigorously developing original processes, and uses incubation companies to expand the market and cultivate hematopoietic function.
“The first mock exam is right in the current international situation, and I believe that this model will be successful, because the market demand for China’s high-tech upgrading is growing.” Said Du Xiaolong.
After the high-efficiency crystalline silicon Cecep Solar Energy Co.Ltd(000591) battery team settled in Songshanhu materials laboratory, successfully built a pilot line for the research and development of new process of high-efficiency crystalline silicon Cecep Solar Energy Co.Ltd(000591) battery, providing a reliable platform for small-scale verification and pilot scale-up of revolutionary process. based on the existing advanced cashmere making process, the team further developed advanced passivation technology by using the pilot test line, and realized the industrial application of high-efficiency crystalline silicon battery mass production technology such as perc battery, TOPCON battery and hjt battery.
In August 2020, the high-efficiency crystalline silicon battery team of Songshan Lake materials laboratory was incubated and established in Songshan Lake materials laboratory in the community to further accelerate the transformation of the team’s R & D achievements. “Because the team used to engage in scientific research, had little experience in doing business, and didn’t know much about finance, policies and laws. The community organized professional tutors in the field to train our employees every month. Many problems in the early stage of enterprise operation can be properly solved, which is also conducive to our subsequent development.” Xiao Chuan, deputy general manager of zhongkepurui and engineer of high-efficiency crystalline silicon battery team, said.
At present, the core of the enterprise focuses on the R & D and production of a series of fast large-area quantitative imaging equipment and wet chemical auxiliary additives. The former will greatly improve the product process detection efficiency of Cecep Solar Energy Co.Ltd(000591) battery enterprises, while the latter will improve the performance of Cecep Solar Energy Co.Ltd(000591) batteries of different materials.
Among them, the fast large-area quantitative imaging series equipment includes surface reflectance detector, film thickness detector, winding detector, 3D profiler, etc. the equipment can obtain the average reflectance and film thickness of the whole surface of silicon wafer within 0.5s, and effectively identify abnormal and unqualified wafers according to the measurement results.
It is understood that at present, zhongkepurui has reached cooperation with Tongwei Co.Ltd(600438) , Longi Green Energy Technology Co.Ltd(601012) and other leaders in the photovoltaic industry, and the team has obtained 15 relevant patents. “at present, enterprises also need to establish a better sales production team and open up the whole chain from R & D to sales. Entrepreneurship is a solid first step.” Du Xiaolong said that in the face of new market demand, the enterprise has a certain foundation for product R & D, and we will continue to work hard to develop more competitive products.
“Only by creating greater value for customers can there be more markets. Entrepreneurship is often a near death. People in the industry must be down-to-earth and can’t aim too high. They need to keep moving forward quickly and make due contributions to the development of industrial technology.” Said Du Xiaolong.
