摘要
利用分子笼封装前驱体而后热解的策略,制备了具有高催化活性的氮掺杂多孔碳(NPC)负载孤立的单个Fe原子(Fe-ISAs/NPC)电催化剂,并作为对电极用于染料敏化太阳能电池(dye-sensitized solar cells,DSSCs)。通过电化学测试研究了Fe-ISAs/NPC对电极的膜厚对DSSCs光电性能的影响。测试结果表明,Fe-ISAs/NPC对电极的膜厚为16μm时,DSSCs的光电转换效率最高(8.03%)。
Herein,we prepared N-doped porous carbon(NPC)loaded with isolated single Fe atom(Fe-ISAs/NPC)electrocatalyst with high catalytic activity as counter electrode for dye-sensitized solar cells(DSSCs)through molecular cage-encapsulated-precursor pyrolysis.Effect of film thickness of Fe-ISAs/NPC counter electrode on the performance of DSSCs was studied by electrochemical measurement.The results showed that the highest photoelectric conversion efficiency of DSSCs was 8.03%when the film thickness of Fe-ISAs/NPC counter electrode was 16μm.
