Herein, we present a straightforward bottom-up synthesis of a high electron mobility and highly light scattering macroporous photoanode for dye-sensitized solar cells. The dense three-dimensional Al/ZnO, SnO(2), or TiO(2) host integrates a conformal passivation thin film to reduce recombination and a large surface-area mesoporous anatase guest for high dye loading. This novel photoanode is designed to improve the charge extraction resulting in higher fill factor and photovoltage for DSCs. An increase in photovoltage of up to 110 mV over state-of-the-art DSC is demonstrated.
在此，我们提出了一种简单的自上而下的方法，合成了一种具有高电子迁移率和高光散射的介孔光阳极，用于染料敏化太阳能电池。致密的三维 Al/ZnO、SnO(2) 或 TiO(2) 主体集成了一个保形钝化薄膜，以减少复合，并具有大表面积的介孔锐钛矿客体，用于高染料负载。这种新型光阳极旨在改善电荷提取，从而提高 DSCs 的填充因子和光电势。与最先进的 DSC 相比，光电势提高了高达 110 mV。
