英文摘要	以3-氨基丙基三甲氧基硅烷(APTS)修饰的二氧化钛为负极制备的染料敏化太阳能电池在100 mW·cm-2的模拟太阳光照下的短路电流、开路电压、光电转换效率分别为18.32 mA·cm-2、775.9 mV、9.15%.而没有经过ATPS修饰的电池三项性能参数分别为18.08 mA·cm-2、749.9 mV、7.70%, 修饰后电池的光电转换效率提高了18.8%, 同时填充因子由0.57提高为0.64. 暗电流-电压曲线显示起始电压从-0.30 V变化到-0.40V, 表明二氧化钛电极和电解液之间的暗反应得到了有效抑制, APTS作为阻挡层减少了二氧化钛电极表面的缺陷与表面态. 另外, 通过...; A dye-sensitized solar cell (DSSC) based on a 3-aminopropyltrimethoxysilane (APTS)-modified TiO2 electrode was fabricated. This cell generated a short current of 18.32 mA . cm(-2), an open voltage of 775.9 mV, and its overall photo-to-electricity conversion efficiency was 9.15% under 100 mW . cm(-2) white light irradiation from a xenon lamp. The three DSSC parameters for the bare TiO2 electrode were found to be 18.08 mA . cm(-2), 749.9 mV, and 7.70%. Compared with the unmodified solar cell, the overall conversion efficiency improved by 18.8% and the fill factor improved from 0.57 to 0.64. This improvement is attributed to the inhibition of the back reaction at the interface between the semiconductor and the electrolyte. The dark current-applied voltage curve shows that the onset voltage shifts from -0.30 to -0.40 V, which indicates a reduction in defects and surface states on the TiO2 surface because of the presence of APTS. Furthermore, special experiments were conducted to investigate the interaction among TiO2, APTS, and the cis-Ru(dcpyH(2))(2)(SCN)(2) dye. In these experiments, APTS and the dye were self-assembled onto a TiO2 electrode in layers. The interaction was characterized by X-ray photoelectron spectroscopy (XPS). Qualitative and quantitative results showed that the - OCH2CH3 was partially removed and it formed mono-bridge or bi-bridge Si-O-Ti bonds. The cis-Ru(dcpyH(2))(2)(SCN)(2) dye adsorbed onto APTS through an electrostatic interaction between - COOH and - NH2 from the dye. FT-IR spectra further confirmed this inner interaction.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000286597200023&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 6; 02; 419-424; 27
