Synthesis of Counter Electrode for Dye-Sensitized Solar Cell Used by Recycled Alkaline (LR6) Battery

摘要

A manganese dioxide doped carbon (MnO2:C) cathode electrode can be applied as counter electrode for dye-sensitized solar cell (DSC). In this study, we proposed a synthesis of MnO2:C material from recycled alkaline (LR6) battery and investigated a properties of counter electrode for DSCs using MnO2:C material. The MnO2:C film counter electrode was used to coat fluoride-doped tin oxide (FTO) glass and the anode of DSC was a TiO2 film on FTO glass. The both electrodes were coated on FTO glass in an area of 2x2 cm(2). The morphological properties of MnO2:C film counter electrode was confirmed by X-ray diffraction (XRD) and scanning electron microscope (SEM). The performance of DSC with MnO2:C film counter electrode was investigated by solar simulator at 100 mW/m(2). The experimental result of prepared DSC showed the open circuit voltage (V-OC) of 0.687 V and the short circuit current (I-SC) was 62.4 mA, respectively. The use of MnO2:C film as counter electrode was sufficient to fabricated and to test a cathode electrode for DSCs application.
