制备了TiO 2/CuInS 2量子点敏化太阳能电池，并通过不同的加热温度和加热时间对光电极的界面连接进行了调制。对TiO 2/CuInS 2光电极的晶体结构和形貌进行了分析，发现量子点的尺寸略有增长。随着加热温度的升高和加热时间的延长，光吸收边逐渐扩大，但对TiO 2/CuInS 2光电极的光吸收强度没有明显影响。优化了量子点的表面状态以及CuInS 2量子点与TiO 2薄膜的界面连接，在300 °C下热处理5 min后，量子点具有良好的电荷分离和电荷转移性能。随着电池界面连接方式的改善，TiO 2/CuInS 2量子点敏化太阳能电池的光电转换效率从4.04%提高到4.68%。
TiO2/CuInS2quantum dot sensitized solar cells are prepared, and the interface connection of photo-electrodes is modulated by different heating temperature and heating time. The crystal structures and morphologies of the TiO2/CuInS2photo-electrodes have been analyzed, which has exhibited slight size growth of QDs. And the optical absorption edges have gradually expanded with the increasing of heating temperature and heating time, which have no obvious changes on optical absorption intensity of TiO2/CuInS2photo-electrodes. The surface states of QDs and interface connection between CuInS2QDs and TiO2films have been optimized, which have exhibited excellent charge separation and charge transfer properties with the heating treatment at 300 °C for 5 min. With the improvement on the interface connection of the solar cells, the photovoltaic conversion efficiency of the TiO2/CuInS2quantum dot sensitize solar cells have been enhanced from 4.04% to 4.68%.
