摘要
铜铟镓硒(CIGS)基太阳电池是一种具有高转换效率的薄膜太阳电池,实验室制备的CIGS电池转换效率已达22.9%,接近于晶硅类电池最高的转换效率。同时CIGS电池还具有吸收系数高,制造成本较低,并且应用非常广泛等优点。然而,在商业化的大规模生产中,CIGS太阳电池不论在效率还是稳定性上仍与晶硅电池存在差距。进一步提升CIGS电池效率,优化电池性能,扩大电池产业化规模是CIGS太阳电池今后发展的必经之路。当前CIGS太阳电池的发展取得的重大成就,主要原因在于人们对CIGS材料与器件原理的进一步认识。本文综合介绍了CIGS太阳电池作为当前热点的潜力和优势,回顾了近期关于CIGS的研究进展,主要包括电池的缓冲层、吸收层和窗口层的改进,及层界面之间的处理手段,这些技术的发展提高了CIGS电池的转换效率,推动了其产业化进程,同时在电池未来发展方面阐述了相关问题,并对解决方案进行了展望。
Copp er indium gallium selenium(CIGS) based solar cells were thin film solar cells with high conversion efficiency.The conversion efficiency of CIGS solar cells prepared in the laboratory reached 22.9%,which was close to the highest conversion efficiency of crystal silicon solar cells.At the same time,CIGS cells also had the advantages of high absorption coefficient,low manufacturing cost,and wide application.However,in large-scale commercial production,CIGS solar cells were still far from silicon-based solar cells in terms of efficiency and stability.Further improving the efficiency of CIGS solar cells,expanding the scale of cells industrialization and optimizing their performance were the only way for the future development of CIGS solar cells.The main achievements of the current development of CIGS solar cells were mainly due to people’s understanding of CIGS materials and device principles.In this paper,the potential and advantages of CIGS solar cells as a hot spot and recent research progresses on CIGS solar cells were reviewed,including the improvement of buffer layer,absorption layer and window layer,as well as the treatment methods between the layers.The development of these technologies improved the conversion efficiency of CIGS solar cells and promoted its industrialization.At the same time,the related problems in the future development of cells and the solutions were discussed.
