The relationship between Copper Oxide thin film structure and photovoltaic power on Cu₂O/TiO₂ thin films

Abstract

In this paper the characteristics of solid state dye-sensitized solar cells prepared by reactive magnetron sputtering is described. The solar cells were constructedas basing the Cu₂O/TiO₂ thin film. From the previous research, it was confirmed that the oxygen flow rate during Cu₂O preparation remarkable affects photovoltaic power. In addtion, the optimum value of the oxygen flow rate was 8.5 sccm. In this study, we examined the improvement of photovoltaic power by the change of film structure.
