Fabrication of CZTS(Se) thin films by single-target sputtering technique and their relevant application in solar cells [PDF]
, 2016 Cu2ZnSnSxSe4-x（CZTSSe）具有合适的禁带宽度（1.5eV）和较高的光吸收系数（α>104cm-1），且元素储量丰富，是最具潜力的高效率、低成本新型绿色光伏材料之一。但是，CZTS材料组分容忍度和单晶区域很小，存在二次相和元素分解等问题，难以制备高质量的CZTS薄膜。目前，CZTS薄膜器件的最高转换效率为12.6%，远低于32%的理论效率。为了发展高效率、低成本的CZTS薄膜技术，大量的研究工作必不可少。 论文的第一部分，采用操作简便的单靶（等化学计量的Cu2ZnSnS4四元化合物靶材 ...
