氮化钛与聚苯乙烯磺酸盐掺杂的聚（3,4-乙烯二氧噻吩）（PEDOT:PSS）的复合薄膜是通过 TiN 和 PEDOT:PSS 的简单机械混合在超声处理下制备的，该复合薄膜被证明可以提供高导电性和优异电催化活性的有效组合网络。复合薄膜已被探索作为染料敏化太阳能电池对电极的替代品。结果表明，这些纳米结构的 TiN-PEDOT:PSS 复合薄膜由于组合网络赋予更有利和更有效的界面活性位点而表现出与 Pt-FTO 对电极相当的优异性能。其中，在相同实验条件下，以TiN(P)-PEDOT:PSS为对电极的电池的能量转换效率达到7.06%，优于以Pt-FTO对电极的电池的6.57%。
The composite films of titanium nitride in conjunction with polystyrenesulfonate-doped poly (3,4-ethylene-dioxythiophene) (PEDOT:PSS) were prepared by a simple mechanical mixture of TiN and PEDOT:PSS under ultrasonication, which was demonstrated to deliver an effectively combined network of both high electrical conductivity and superior electrocatalytic activity. The composite films have been explored as an alternative for the counter electrodes of dye-sensitized solar cells. It was manifested that these nanostructured TiN-PEDOT:PSS composite films displayed excellent performance comparable to Pt-FTO counter electrode due to the combined network endowing more favorable and efficient interfacial active sites. Among them, the energy conversion efficiency of the cell with TiN(P)-PEDOT:PSS as counter electrode reached 7.06%, which was superior to 6.57% of the cell with Pt-FTO counter electrode under the same experimental conditions.
