摘要
随着可再生能源需求的增长,太阳电池作为一种可持续的清洁能源技术核心载体,受到广泛关注。单晶硅太阳电池凭借其低成本与高可靠性优势,历经数十年发展已成为光伏市场中的主导技术。从产业化发展的角度系统综述单晶硅电池技术进展和研究现状,重点介绍了钝化发射极和背面接触(passivated emitter and rear contact,PERC)电池、隧穿氧化钝化接触(tunnel oxide passivated contact,TOPCon)电池、异质结(heterojunction,HJT)电池和全背接触(back contact,BC)电池等4类典型单晶硅太阳电池的结构特征、性能优势及制备工艺,进一步指出当前高效单晶硅太阳电池产业化面临的挑战,最后从硅片寿命提升、图形化方案和金属化技术等方面展望了技术发展趋势。
As the increasing demand for renewable energy,solar cells,as a sustainable core carrier of clean energy technology,have been widely concerned.Monocrystalline silicon solar cells,with their advantages of low cost and high reliability,have become the dominant technology in the photovoltaic market after decades of development.This article systematically reviews the technological progress and research status of monocrystalline silicon cell technology from the perspective industrialization development.It mainly introduces the structural characteristics,performance advantages,and preparation processes of four typical types of monocrystalline silicon solar cells,including passivated emitter and rear contact(PERC)cells,tunnel oxide passivated contact(TOPCon)cells,heterojunction(HJT)cells and full back contact(BC)cells.It further points out the current challenges faced by the industrialization of high-efficiency monocrystalline silicon solar cells.Finally,it looks forward to the technological development trends from aspects such as the improvement of silicon wafer lifespan,graphical solutions and metallization technology.
