    • Provided is a method for fabricating a high-efficiency flexible thin film solar cell using a chalcopyrite-based compound semiconductor, including: forming a sacrificial layer on a substrate; forming a solar cell structure including a diffusion barrier dielectric on the top of the sacrificial layer; forming a support film on the top of the solar cell structure; carrying out selective etching of the sacrificial layer to separate the solar cell structure and the support film from the substrate; and integrating the solar cell structure with a heterogeneous flexible host substrate and removing the support film. In the high-efficiency flexible thin film solar cell using a chalcopyrite-based compound semiconductor according to the present disclosure, the thin film of GaAs diffusion barrier dielectric prevents diffusion of impurities since it has an optimized thermal expansion coefficient with reference to the CIGS (Cu(In,Ga,Al)(Se,S)) absorption layer and the lower electrode molybdenum layer, and inhibits lower electrode cracking and CIGS layer separation caused by the difference of thermal expansion coefficient of the CIGS layer, thereby improving the efficiency of the solar cell. In addition, the method uses heterogeneous integration technology and epitaxial lift off (ELO) that enables recycle of a substrate, and thus it is possible to provide a high-efficiency flexible thin film solar cell having improved cost efficiency and flexibility.
    • 提供一种使用黄铜矿类化合物半导体制造高效柔性薄膜太阳能电池的方法,包括:在基板上形成牺牲层; 在所述牺牲层的顶部上形成包括扩散阻挡电介质的太阳能电池结构; 在太阳能电池结构的顶部形成支撑膜; 对牺牲层进行选择性蚀刻以将太阳能电池结构和支撑膜与衬底分离; 并且将太阳能电池结构与异质柔性主体衬底集成并移除支撑膜。 在根据本公开的使用基于黄铜矿的化合物半导体的高效率柔性薄膜太阳能电池中,GaAs扩散阻挡介电层的薄膜防止杂质的扩散,因为它具有参考CIGS(Cu (In,Ga,Al)(Se,S))吸收层和下电极钼层,抑制由CIGS层的热膨胀系数的差异引起的下电极裂纹和CIGS层分离,从而提高 太阳能电池。 此外,该方法使用能够使基板再循环的异质集成技术和外延剥离(ELO),从而可以提供具有改进的成本效率和灵活性的高效柔性薄膜太阳能电池。
