摘要: 本文采用溶胶–凝胶法制备了钙钛矿结构La0.7Sr0.3MnO3 (LSMO)靶材，并利用脉冲激光沉积法在玻璃衬底上制备了不同厚度(67.5 nm和579 nm)的LSMO薄膜。X射线衍射结构分析表明薄膜具有纯相的钙钛矿结构，结晶度良好。鉴于钙钛矿结构锰氧化物的催化活性，将其应用在染料敏化太阳能电池(DSSC)对电极上，分别研究了LSMO、Pt/LSMO作为对电极时DSSC的光电转换特性，初步探索了钙钛矿结构锰氧化物作为DSSC电极的可行性。本文为探索DSSC新的对电极提供一种有益尝试，为后续开展包含钙钛矿结构锰氧化物的DSSC体系中光电转换性能改进研究提供实验基础。
Abstract: In this paper, perovskite La0.7Sr0.3MnO3 (LSMO) targets were prepared by sol-gel method, and LSMO films with different thickness (67.5 nm and 579 nm) were deposited on glass substrates by pulsed laser deposition method. Crystal structure charactered by X-ray diffraction shows that the films present pure perovskite structure phase and have good crystallinity. In view of the catalytic activity of perovskite manganese oxide, the films were applied as counter electrode in dye-sensitized solar cell (DSSC). Photoelectric conversion characteristics of DSSC with LSMO and Pt/LSMO as counter electrodes were studied, and the feasibility of perovskite manganese oxide as DSSC electrode was preliminally explored. This paper provides a beneficial attempt to explore a new kind of counter electrode of DSSC, and provides an experimental basis for the study about the improvement of photoelectric conversion performance in DSSC system containing perovskite manganese oxide.
