2023年中国光伏技术进展综述OA

In 2023,China's PV technology has developed rapidly.This paper systematically summarizes the development of China's PV technology in 2023 from the aspects of c-Si and silicon wafers,crystalline silicon solar cells and their PV modules,thin-film solar cells and their PV modules,new solar cells,integration and application of PV power generation systems,PV power converters and balance components,digital technology for the entire lifecycle of PV power stations,PV power generation standards and empirical testing,and photoelectric conversion efficiency of solar cells.It objectively depicts the overall map of China's PV technology innovation.The following conclusions have been drawn:1)The energy consumption indicators of the trichlorosilane method(improved Siemens method)and the silane method technology have reached the international advanced level,and the recharged czocharlski technology(RCz)is still the main silicon rod production method.The continuous czochralski monocrystal(CCz)technology combined with granular silicon materials continues to make progress.2)The market share of n-type solar cells is rapidly increasing,TOPCon solar cells are being mass-produced,HJT solar cell production capacity continues to increase,and BC solar cells are achieving mass production.The photoelectric conversion efficiency of solar cells such as c-Si solar cells,perovskite solar cells,perovskite/c-Si stacked solar cells,CZTSSe thin film solar cells,and organic solar cells has repeatedly set world records.3)The multi-level and three-dimensional PV power generation application system is constantly enriching,and diversified application models such as large-scale ground PV power stations,distributed PV power stations,offshore floating PV power stations,space-based/space PV power generation systems,and mountain PV power stations are flourishing.
