Accelerating Low-Carbon Transformation: Photovoltaic Power Generation Speeds into the 'Fast Lane'!
In the desert, rows of photovoltaic power generation solar panels are spread out neatly, delivering a steady stream of clean energy power to the surrounding areas; on the sea, a semi-submersible offshore platform stands among them, achieving stable and balanced new energy power generation all year round and all day long. ; In mountainous areas, photovoltaic power generation facilities on the hillsides start to operate with the sunshine, and Chinese medicinal materials such as honeysuckle and vitex under the photovoltaic panels bring additional planting income to local farmers...
From "following" to "leading", my country's photovoltaic industry has achieved leapfrog development in recent years, and the degree of localization of key links has increased significantly. The latest data from the National Energy Administration shows that in the first quarter of 2024, my country's new grid-connected photovoltaic power generation capacity was 45.74 million kilowatts, of which 21.93 million kilowatts were added to centralized photovoltaics and 23.81 million kilowatts to distributed photovoltaics. Photovoltaic power generation is accelerating its development. "Fast lane".
Technology empowers innovation. The rapid development of photovoltaic power generation cannot be separated from the help of upstream manufacturing. The research and innovation of key technologies inject core power into photovoltaic power generation. In Jiangsu, in a high-tech test workshop with an investment of more than 300 million yuan and an area of nearly 6,000 square meters, various robots waved their arms and gently picked up thin battery sheets; electronic screens of all sizes displayed , groups of data flashed continuously, showing the various performances of the new equipment.
"Photovoltaic cell production equipment is updated and iterated very quickly, basically every three years." According to the relevant person in charge, local shipments surged in the first quarter, and all workshops were working overtime and operating at full capacity, and key technologies continued to make breakthroughs. . At present, the local photovoltaic industry chain covers all production and manufacturing links except polycrystalline silicon materials, and also lays out wind and solar complementary, efficient energy storage, energy Internet and other fields.
Battery technology is the core area of photovoltaic manufacturing. The innovative research and development of perovskite photovoltaic technology has brought broader development prospects to photovoltaic power generation. "Compared with traditional crystalline silicon cells, perovskite photovoltaic technology can theoretically reduce production energy consumption from 1.52 kilowatts/hour to 0.12 kilowatts/hour, and the production cycle from 72 hours to 3 hours." According to relevant experts, in recent years In recent years, perovskite solar cell technology has continued to innovate, and its advantages in raw material prices, processing cycles, broadcast efficiency, and cost of electricity have become increasingly obvious.
According to reports, the stacked cell of perovskite and crystalline silicon can realize the utilization of the full spectrum of solar energy, and its photoelectric conversion efficiency can reach 40%, which is twice the conversion efficiency of currently used photovoltaic cells on a large scale. In Qinghai, the Gonghetalatan 300,000-kilowatt photovoltaic construction project was successfully connected to the grid to generate electricity, becoming the world's largest commercial size megawatt-scale perovskite module photovoltaic demonstration project. The localization rate of core equipment reached more than 90%, and the average annual carbon dioxide emission reduction was approximately 473,200 tons; in Shandong, the local first perovskite photovoltaic technology innovation center was officially established. By focusing on the problems faced by the industrialization of key materials, technologies, equipment, processes and other perovskite solar cells, the development of general perovskite solar technology will be established. And test and detection platform...
"Innovation in the photovoltaic industry includes three aspects, namely cutting-edge technology innovation, development model innovation and institutional mechanism innovation." Relevant experts said that the photovoltaic industry has huge potential for future development. It is necessary to continue to strengthen technological innovation, drive core key technologies, and persist in independent innovation. . We will make comprehensive efforts in terms of equipment, materials, products, etc. to expand new application scenarios, further reduce costs, and consolidate and improve the competitiveness of the industrial chain.
Technological innovation in the upstream manufacturing industry has created a solid technical foundation for photovoltaic power generation, while downstream photovoltaic applications have further expanded the development potential of the photovoltaic industry. In recent years, "cross-border integration and multi-energy complementation" have become key words for my country's energy green and low-carbon transformation, and the "photovoltaic +" model continues to empower all walks of life. Since the State Council issued the "Guiding Opinions on Accelerating the Establishment and Improvement of a Green, Low-Carbon and Circular Development Economic System", Henan, Zhejiang, Anhui, Ningxia, Sichuan, Shanghai and other places have issued relevant implementation plans to encourage the in-depth development of "photovoltaic +" and distributed photovoltaic develop.
Guizhou has launched the "photovoltaic + agriculture" model, exploring the application of "agricultural and photovoltaic complementation" industries, and creating a new business format that integrates green energy technology and traditional agriculture; Jiangsu has put into operation the country's first ultra-large-scale "photovoltaic + air film" photovoltaic power station project, effectively avoiding The problem of dust spillage from local coal, sand and other bulk materials can reduce sewage discharge by about 280,000 tons per year; Gansu explores the green development path of "photovoltaic + breeding" and installs solar panels for local cattle farms, using "spontaneous self-use, The consumption method of "residual surplus is connected to the grid" brings additional power generation income to local farmers...
"Photovoltaic power generation has strong compatibility and can be integrated with construction, transportation, agriculture and other fields to achieve comprehensive benefits and value-added utilization of space." Xiong Minfeng, deputy director of the New and Renewable Energy Department of the National Energy Administration, said that the scale of my country's photovoltaic power generation development Continuous innovation and continuous expansion of application scenarios. It is necessary to adhere to the "photovoltaic +" integrated development model and expand new photovoltaic application scenarios, new models, and new business formats.
