Through elongating the end or side alkyl chains of dye molecules, we decorate anatase nanocrystals with a thicker organic assembly featuring a smaller tilt angle of the D-π-A backbone with respect to the surface normal, which retards the interfacial charge recombination and confers a higher photovoltage output on mesoscopic cobalt solar cells displaying an over 10% power conversion efficiency at the AM1.5G conditions.
通过延长染料分子的端基或侧链烷基，我们用具有更小的 D-π-A 主链与表面法向倾斜角的较厚有机组装体来修饰锐钛矿纳米晶体，这延迟了界面电荷复合，并在介观钴太阳能电池上赋予更高的光伏电压输出，在 AM1.5G 条件下显示超过 10%的功率转换效率。
