Photovoltaic power generation enters the "fast lane" of low-carbon energy transformation and accelerates again

2024-05-14

In the desert, rows of photovoltaic solar panels are neatly laid out, delivering a continuous source of clean energy electricity to the surrounding areas; At sea, a semi submersible offshore platform stands tall, achieving stable and balanced new energy generation throughout the year and all weather; In mountainous areas, photovoltaic power generation facilities on mountain slopes start to operate with the sunlight, and Chinese medicinal materials such as honeysuckle and magnolia under photovoltaic panels bring additional planting income to local farmers... From "following" to "leading", in recent years, China's photovoltaic industry has achieved leapfrog development, and the degree of localization in key links has significantly increased. The latest data from the National Energy Administration shows that in the first quarter of 2024, China's photovoltaic power generation added 45.74 million kilowatts of grid connected capacity, of which centralized photovoltaic added 21.93 million kilowatts and distributed photovoltaic added 23.81 million kilowatts. Photovoltaic power generation is accelerating into the "fast lane" of development. Technology empowers innovation, and the rapid development of photovoltaic power generation cannot be achieved without the support of upstream manufacturing. The research and innovation of key technologies inject core power into photovoltaic power generation. In Jiangsu, a high-tech experimental workshop with an investment of over 300 million yuan and an area of nearly 6000 square meters, various types of robots wave their arms and gently grasp thin battery cells; On electronic screens of all sizes, groups of data flicker incessantly, showcasing the various performance of the new device. "The update and iteration speed of photovoltaic cell production equipment is very fast, and it basically needs to be replaced every 3 years." According to the relevant person in charge, the local shipment volume increased sharply in the first quarter, and each workshop worked overtime to operate at full load, continuously breaking through key technologies. At present, the local PV industry chain covers all production and manufacturing links except for polysilicon materials, and at the same time, the layout of wind and solar complementary, efficient energy storage, energy Internet and other fields. Battery technology is the core field of photovoltaic manufacturing, and the innovative research and development of perovskite photovoltaic technology has brought broader development prospects for photovoltaic power generation. "Compared to traditional crystalline silicon cells, perovskite photovoltaic technology theoretically can reduce production energy consumption from 1.52 kW/hour to 0.12 kW/hour, and production cycle from 72 hours to 3 hours." Experts explain that in recent years, perovskite solar cell technology has continued to innovate, and its advantages in raw material prices, processing cycles, broadcasting efficiency, and electricity cost have become increasingly apparent. It is reported that the stacked cells of perovskite and crystalline silicon can achieve full spectrum utilization of solar energy, with a photoelectric conversion efficiency of up to 40%, which is twice the conversion efficiency of current large-scale photovoltaic cells. In Qinghai, the Gonghe Taratan 300000 kilowatt photovoltaic construction project has successfully connected to the grid for power generation, becoming the world's largest commercial scale megawatt level perovskite module photovoltaic demonstration project. The localization rate of core equipment has reached over 90%, and the annual average carbon dioxide reduction is about 473200 tons; In Shandong, the first perovskite photovoltaic technology innovation center in the local area has been officially established. By focusing on the problems faced by the industrialization of key materials, technologies, equipment, processes, and other aspects of perovskite solar cells, a perovskite solar general technology development and testing platform has been built... "The innovation of the photovoltaic industry includes three aspects: cutting-edge technology innovation, development mode innovation, and institutional mechanism innovation." Experts said that the future development potential of the photovoltaic industry
