Abstract

Highlights: Preparation of PdSe via dip coating based multilayer deposition technique as cathode for DSSC. Influence of Pd content at the fixed content of Se on the performance of the device has been investigated. Dominant phase of Pd and minor phase of Se exist in the sample. DSSC based PdSe demonstrates comparable η compared Pt-based device. Device utilizing PdSe cathode with the Se:Pd ratio of 1:6 demonstrates the highest η of 3.14 %. Abstract: This work is concerned with the preparation of PalladiumSelenide (PdSe) via a simple technique that is dip coating based multilayer deposition technique as cathode for dye-sensitized solar cell (DSSC). The influence of Pd content at the fixed content of Se on the performance of the device has been investigated. The XRD analysis reveals that the dominant phase of Pd and minor phase of Se exist in the sample. The photovoltaic measurement results reveals that the DSSC based PdSe CE demonstrates comparable power conversion efficiency ( η ) compared with that of the Pt based device. The highest η of the device utilizing PdSe cathode with the Se:Pd ratio of 1:6 was 3.14 %, while that of the device with Pt cathode was 4.83%. The PdSe CE based device with the ratio of 1:6 owns the highest η due to the highest IPCE in the visible region . In conclusion, the performance of the device is found to be significantly affected by Pd content.
