A novel porous fluorine doped tin oxide (PFTO) conductive framework was introduced to counter electrodes (CEs) for dye-sensitized solar cells (DSSCs). When modified by platinum (Pt) or carbon (C), the PFTO conductive framework displays high catalytic activity to I(-)/I3(-) redox couples. Power conversion efficiencies of 6.09% and 5.81% were obtained in the DSSCs based on Pt and C modified PFTO CEs respectively, which were close to that of DSSCs with Pt coated FTO glass (6.05%) and Pt sheet (6.26%) CEs. Maximum limiting performances of the CEs were obtained from the polarization curves. The CE based on PFTO showed higher maximum limiting power conversion efficiency (20%) compared with the planar FTO substrate Pt CE (18%), with the increase of its surface area and electrocatalytic activity.
引入了一种新型的多孔氟掺杂氧化锡（PFTO）导电框架作为染料敏化太阳能电池（DSSC）的对电极（CE）。当修饰为铂（Pt）或碳（C）时，PFTO 导电框架对 I(-)/I3(-)氧化还原对显示出高催化活性。基于 Pt 和 C 修饰的 PFTO CE 的 DSSC 的功率转换效率分别为 6.09%和 5.81%，接近于具有 Pt 涂覆 FTO 玻璃（6.05%）和 Pt 片（6.26%）CE 的 DSSC。从极化曲线获得了 CE 的最大限制性能。与平面 FTO 基底 Pt CE（18%）相比，基于 PFTO 的 CE 显示出更高的最大限制功率转换效率（20%），这归因于其表面积和电催化活性的增加。
