摘要:

柔性染料敏化太阳能电池(DSSCs)作为一种新型的化学太阳能电池,因其精简的封装工艺、较低廉的价格、高的化学稳定性以及可弯折等优点而备受关注. 本文介绍了一种新型的柔性DSSC的制备,其光阳极为高度有序的氧化锌(ZnO)纳米线阵列,对电极为柔性、导电、透明的网状铂(Pt networks)电极. 相对于传统的铂对电极而言,这种Pt networks对电极不仅具有优异的导电能力,还展现了极好的透光性(方阻~ 100 Ω•sq-1,~80%透光率)和催化性能,此外,Pt networks电极可构筑于任意弯曲的衬底,具有优异的机械耐弯折性能. 在ZnO纳米线阵列的DSSCs的应用中,基于Pt networks膜的柔性DSSC的转化效率比铂纳米丝阵列 (Pt nanofiber arrays, Pt NFs)膜高出了32%.

Abstract:

Flexible dye-sensitized solar cells (DSSCs) have received widespread attentions in recent years because of their ease of fabrication, low production cost, relatively high chemical stability and flexibility. We report the fabrication of ZnO DSSCs based on the highly flexible, conducting, catalytic and transparent Pt networks counter electrode, and the performance of this solar cell was characterized by SEM, XRD, polarized fluorescence microscope, motor, I-V test station and electrochemical workstation. Compared to Pt nanofiber arrays (NFs), Pt networks not only show a better conductivity, but also exhibit superior transparency and catalytic activity. Furthermore, Pt networks electrode could be constructed on arbitrary flexible substrates. The fabricated flexible ZnO DSSC based on Pt networks counter electrode achieved 1.33% photoelectric conversion efficiency, which is 32% higher than that based on Pt NFs.
