Enhanced performance of solid state dye sensitized solar cells with e-beam irradiated composite polymer electrolytes |
| 초록 |
The use of polymer electrolytes in dye-sensitized solar cells has been a viable and promising alternative for the high performance, long-term stability and successful removal of the traditional liquid electrolytes. In the present study, we are attempted to prepare a noble heteropolyacids (HPAs)-polymer composite material with irradiation of electron beam (e-beam) with a source 1.3 MeV and dose rate of 15 kGy/min. Finally, the modified composite with iodine/iodide was applied as a polymer gel electrolyte for the fabrication of solid-state DSSC. Our results shows typical photocurrent–voltage (I-V) curves of fabricated DSSCs with VOC of 0.588 volt and ISC of 9.68 mA/cm2 with 3.35% overall conversion efficiency under 100mW/cm2 illumination. e-beam irradiation on the composite materials is essential step to increase ionic conductivity of composite and performance in device, which is a noble and simple technique. The prepared composite materials were characterized by XRD, FT-IR, DSC, TGA, ionic conductivity and photovoltaic performance tests. |
