| 摘 要： | P型半导体Cu_2ZnSnS_4(CZTS)由于具有最佳的直接带隙(1.0~1.5eV)、高的光吸收系数(超过104 cm~(-1))以及丰富、无毒的元素组成,使其成为商业化低成本太阳能电池最有希望的候选材料之一。然而,材料本身的一些缺陷制约了CZTS薄膜太阳能电池效率的提高。为了提高CZTS薄膜太阳能电池的效率,研究者们使用其他阳离子部分取代Cu、Zn或Sn来改善CZTS的缺陷。从CZTS的3种不同取代位置出发,综述了近年来各种阳离子部分取代CZTS的研究进展,同时对阳离子部分取代CZTS材料的发展前景进行了展望。

| Abstract: | Cu2ZnSnS4 (CZTS),a p-type semiconductor,is one of the most promising candidates for application in low-cost solar cells,owing to its optimal direct band gap (ca.～1.0-1.5 eV),high absorption coefficient (over 104 em 1) in the visible wave length region,as well as its composition of naturally abundant and nontoxic elements.However,the intrinsic limitations of CZTS,such as secondary phases,antisite defects,carrier lifetime,etc,hinder the improvement of the efficiency of CZTS thin-film solar cell.In order to enhance the efficiency of CZTS thin-film solar cell,researchers have used partial substitution of Cu,Zn or Sn by other cations to improve the defects of CZTS.In this paper,the progress of partially substituted CZTS in recent years is reviewed from three different substitution sites for CZTS.At the same time,the development prospect of partially substituted CZTS is discussed. |
