将铂（Pt）薄膜电沉积到FTO玻璃上聚苯乙烯（PS）模板的空隙中。通过加热去除模板后，Pt膜形成一种新颖的亚微米结构，其中有组织的孔隙（称为e-PtOP）。具有这种铂结构的FTO玻璃用作染料敏化太阳能电池（DSSC）的对电极（CE）。与没有PS模板的Pt薄膜电池（16.63 mA cm - 2）相比，e-PtOP具有更高的比表面积，从而具有更高的电催化能力，使得相关DSSC的短路电流密度（18.94 mA cm - 2）更高。在e-PtOP上进一步溅射薄层Pt，以增加DSSC与相应CE的填充系数。因此，与没有PS模板的Pt薄膜电池相比，该电池的功率转换效率从6.03提高到8.89%。
A platinum (Pt) film is electro-deposited into the voids of a polystyrene (PS) template on an FTO glass. After the removal of the template by heating, the Pt film forms a novel submicron structure with organized pores in it (designated as e-PtOP). The FTO glass with this Pt structure is used as the counter electrode (CE) for a dye-sensitized solar cell (DSSC). Higher surface area, and thereby higher electro-catalytic ability of the e-PtOP render higher short-circuit current density for the pertinent DSSC (18.94 mA cm−2) than that of the cell with a Pt film obtained without PS template (16.63 mA cm−2). A thin layer of Pt is further sputtered onto the e-PtOP to render an increased fill factor of the DSSC with the corresponding CE. Consequently, the power-conversion efficiency of this cell is thus enhanced from 6.03 to 8.89%, with reference to the cell with a Pt film obtained without PS template.
