| 摘 要： | 针对粉体MOF衍生材料存在制备工艺复杂、薄膜厚度难以控制等问题,我们通过液相外延分步生长法制备了一种金属有机框架薄膜(PIZA-1),然后以其作牺牲模板,在惰性氛围中制备了一种CoSe_2和N共掺杂的碳膜(CoSe_2/N-CF),并用作DSSC对电极,其具有制备简单、粘结力强、厚度可调等优势。系统表征了CoSe_2/N-CF形貌特点、结构性质及电化学性能,并深入研究了不同厚度薄膜、CoSe_2颗粒大小对DSSC的光伏性能的影响。结果表明,CoSe_2/N-CF-15电极具有优异的催化活性,所组装的DSSC获得了8.68%的光电转化效率(PCE),高于相同条件下Pt电极组装电池的PCE(7.97%)。

| Abstract: | Aiming at the problems of complex preparation process and difficult to control film thickness of powder MOF-derived materials, we used a facile method to prepare the CoSe2 and N co-doped carbon film (CoSe2/N-CF) derived from metal-organic framework thin film materials (PIZA-1) as counter electrode in DSSC, which takes advantage of simple preparation, strong adhesion and adjustable thickness. The morphology, structure and electrochemical performance of CoSe2/N-CF were systematic characterized and the relationship between film thickness and size of CoSe2 with photovoltaic performance of DSSC was discussed. The CoSe2/N-CF-15 exhibited outstanding catalytic activity and remarkable power conversion efficiency (PCE) of 8.68%, which is higher than that of Pt (7.97%). |
