Dye-sensitized solar cells using graphene-based counter electrode

Kai‐Hsiang Hung Yi‐Sheng Li Hong‐Wen Wang

Graphene film was fabricated using graphene oxide (GO) prepared from a modified Hummers' method. The reduction of GO (rGO) was accomplished by coating the GO paste on a piece of glass and immersing into a Ti ⁺³ solution. The freeze drying (FD) process employed for drying GO before its forming of paste and coating into a film exhibits a profound effect on the quality of final graphene counter electrode. The graphene electrode obtained using freeze drying process exhibits a porous structure and is an excellent replacement for the Pt counter electrode of dye-sensitized solar cells (DSSCs). The conversion efficiency for the FD-rGO-based DSSC reaches 6.21%, which is much higher than that of the normal Pt-based DSSC 5.62% using standard P25 materials. The much more reaction sites on the porous FD-rGO-film electrode than the smooth Pt electrode are considered to be the major reason for this high performance.

RESEARCH ON THE EFFECT OF CARBON CONTENT IN MOLYBDENUM DISULFIDE PRETREATED AT HIGH TEMPERATURE WITH NITROGEN

China Molybdenum Industry (2011)

BU Chun-yang

Carbon contained in the lubricating grade molybdenum disulfide prepared with natural method,not only reduces product purity,but also affects the usability.Based on the analysis of carbon source,the method of pretreating molybdenum concentrates which is the raw materials of molybdenum disulfide at high temperature was put forward.The effect of nitrogen flow rate,temperature and time in the carbon content of molybdenum concentrates was inspected.The lubricating grade molybdenum disulfide was prepared by molybdenum concentrates treated in high temperature with nitrogen,which can reduce 30% carbon content.The purity of molybdenum disulfide can increase by 0.3%.
