摘要：

In recent article, ligand octaaza-bis-alpha-diimine and its Yb complex grafted upon GO have been synthesized and characterized using scanning electron microscopy, fourier transform infrared spectroscopy, energy dispersive spectroscopy, raman spectroscopy, x-ray diffraction, and cyclic voltammetry techniques. The composites with varying ratio's GO/Yb (1:1), (1:3) and (1:10) have been investigated as counter electrode in dye sensitized solar cell. The fabricated device was analysed using current density-voltage, incident photon-to-current conversion efficiency, and electrochemical impedance spectroscopy techniques. The device fabricated with highest ratio (1:10), exhibit the highest Voc, Jsc values and it showed the maximum PCE value of 7.98%. Due to the ho-mogeneous distribution of catalytic Yb particles on the surface of RGO, the RGO/Yb CE demonstrated effective electrocatalytic activity. According to the findings, a DSSC with RGO/Yb CE can demonstrate the efficiency highest than platinum (Pt) CE and thus can replace traditional Pt CE DSSCs to reduce the cost of solar cells.
