摘要
硫化锌(ZnS)是一种新兴的用于无镉薄膜太阳能电池的交替n型缓冲层。本研究采用一种独特的甘油和酒石酸混合物，在脉冲电沉积过程中产生相纯ZnS。此外，适当优化脉冲参数有助于在不进行沉积后热处理的情况下制备结晶ZnS薄膜。通过x射线衍射(XRD)和微拉曼分析证实，沉积膜表现出立方ZnS。光学研究表明，在300 ~ 900 nm波长范围内，平均透过率为71%，带隙为3.8 eV。Mott-Schottky分析证实了ZnS的n型半导体行为，推断其平带电位为- 1.0 V vs SCE。采用经济的脉冲电沉积方法制备的结晶ZnS薄膜无需热处理步骤，并在光电化学电池中作为光阳极进行了演示，适合于相关应用。
Pulse electrodeposited zinc sulfide as an eco-friendly buffer layer for the cadmium-free thin-film solar cells
Zinc sulfide (ZnS) is an emerging alternate n-type buffer layer for the cadmium-free thin-film solar cells. The present research adopts a unique mixture of glycerol and tartaric acid for the emergence of phase-pure ZnS during pulse electrodeposition. Besides, proper optimization of pulse parameters aid in producing crystalline ZnS films with no post-deposition heat treatment. The as-deposited films exhibit cubic ZnS as confirmed from X-Ray Diffraction (XRD) and micro-Raman analyses. The optical study reveals an average transmittance of 71% in the wavelength spread of 300–900 nm with a band gap of 3.8 eV. The n-type semiconducting behavior of ZnS is affirmed from the Mott-Schottky analysis and the flat band potential is inferred to be −1.0 V vs SCE. The crystalline ZnS films produced from the economic pulse electrodeposition method devoid of heat treatment step, with their demonstration as photoanode in photoelectrochemical cells are suitable for the relevant applications.
