ENERGY &ENVIRONMENTAL MATERIALS, Volume 8, Issue 6, November 2025.Sb‐Ge‐Se thin films are grown by selenization of co‐evaporated Sb and Ge layers with energy band gaps from 1.41 to 1.83 eV. The coexistence of Sb2Se3 and GeSe2 is identified by GIXRD, FTIR, XPS, and Raman. First Sb‐Ge‐Se thin film solar cells are fabricated with 1.34% performance, probably limited by the CdS diffusion into the active layer and high ...

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 ...
