DEVELOPMENT STATUS AND PROSPECTS OF SOLAR-GRADE SILICON WAFER INDUSTRY IN CHINA
摘要
Abstract
The PV industry plays a crucial role in the field of renewable energy.Solar-grade silicon wafers(hereinafter referred to as silicon wafers)serve as the core component of the PV industry chain and are the basic material for solar cells,with their quality directly determining the electrical performance of solar cells and PV modules.High-quality development of silicon wafers is of great significance for achieving emission peak and carbon neutrality goals.This paper first introduces the classification and preparation technologies of silicon wafers,as well as the requirements of various solar cells for silicon wafers.It then analyzes the current development status,opportunities,and challenges of silicon wafer industry in China.Finally,it provides an outlook on the development prospects of silicon wafer industry in China and offers relevant suggestions.The analysis results show that:1)Due to the advantages of higher photoelectric conversion efficiency and better stability in solar cells prepared from n-type mono-Si wafer,meets the high-quality development needs of the PV industry,it will become the mainstream product in the silicon wafer market in the future.2)The current state of the silicon wafer industry chain is primarily reflected in four aspects:stable upstream raw material supply,mature midstream manufacturing technology,broad downstream application market prospects,and close collaboration among upstream,midstream,and downstream of the industrial chain.3)The development opportunities for silicon wafer industry in China mainly lie in three aspects:favorable policies promoting industry growth,demand driving industry development,and domestic substitution accelerating industry growth.4)Silicon wafer industry in China faces challenges in three main areas:declining silicon wafer prices,rising silicon material costs,overcapacity in silicon wafer production,shortage of technical talent,intensified market competition,and ongoing industry consolidation.5)Future efforts to promote the development of the silicon wafer industry can focus on three aspects:driving technological innovation,guiding enterprises toward healthy development,and expanding talent pools.关键词
