Synthesis of platinum/reduced graphene oxide composite pastes for fabrication of cathodes in dye-sensitized solar cells with screen-printing technology

摘要

Platinum/reduced graphene oxide (Pt/rGO) composite materials with different mass ratios were fabricated by thermal decomposition method from H2PtCl6 and reduced graphene oxide (rGO) as precursors. The Pt/rGO composites were used for fabrication of Pt/rGO cathodes by the screen-printing method. The electrochemical properties of the fabricated cathodes were measured using cyclic voltammetry. The dye-sensitized solar cells (DSSCs) were assembled from fabricated cathodes and tested by current density-voltage
