Carbon Black Paste Combined with Conductivity-enhanced CuSCN for Improved Performance in Quasi-solid-state Dye-sensitized Solar Cells
Vast improvement in the performance of a dye-sensitized solid-state solar cell of TiO2/N719/modified CuSCN is observed when carbon paste is applied on CuSCN. AC-impedance analysis reveals the existence of the ionic nature of the modified CuSCN material, and it is further developed when carbon paste is applied on CuSCN in the solar cell. Voltage-transient spectra of decay analysis show the improvement of the lifetime of the photogenerated electrons and thus improve the voltage in the carbon-paste-applied solar cell.
