中文摘要：

SnO2 nanosheet 电影在厚度的大约 200 nm 成功地在做氟的符号的锡氧化物(FTO ) 上被制作由一条灵巧的答案成年的途径的玻璃。准备 SnO2 nanosheet 电影在敏化染料的太阳能电池(DSC ) 作为在 nanocrystalline TiO2 电影和 FTO 底层之间的界面的层被使用。试验性的结果证明 SnO2 nanosheet 的介绍拍摄不仅在 electrolyte/FTO 接口压制电子背运输反应而且沿着 SnO2 nanosheets 提供一条有效电子转变隧道，并且作为结果，增加开的电路电压和短当前的密度，并且最后从3.89%～4.62%为 DSC 改进变换效率。

英文摘要：

SnO2 nanosheet films about 200 nm in thickness are successfully fabricated on fluorine-doped tin oxide （FTO） glass by a facile solution-grown approach. The prepared SnO2 nanosheet film is appfied as an interfacial layer between the nanocrystalline TiO2 film and the FTO substrate in dye-sensitized solar cells （DSCs）. Experimental results show that the introduction of a SnO2 nanosheet film not only suppresses the electron back-transport reaction at the electrolyte/FTO interface but also provides an efficient electron transition channel along the SnO2 nanosheets, and as a result, increasing the open circuit voltage and short current density, and finally improving the conversion efficiency for the DSCs from 3.89% to 4.62%.
