Effect of light scattering TiO2 particles on the performance of flexible dye sensitized solar cells |
| 초록 |
In this paper, the efficient flexible dye sensitized solar cells (DSSCs) were constructed by using TiO2 nanoparticles (P-25) with light scattering TiO2 nanoparticles (200-300 nm) based thin film electrodes. The flexible electrodes were prepared by mixing of TiO2 nanoparticles and light scattering TiO2 particles into the solution of titanium tertaisopropoxide and ethanol and deposited on indium tin oxide Polyethylene Naphthalate (ITO-PEN) substrates. It was found that dye absorption of TiO2 increased as increasing the amount of light scattering TiO2 particles in TiO2 paste. The reasonable high conversion efficiency of 2.25% with JSC of 5.4 mA/cm2, VOC of 0.768 V and FF of 0.54 was obtained with the flexible DSSC fabricated with optimized TiO2 coated ITO-PEN electrode. The significant improvement in photovoltaic performance is attributed to efficiently improved dye absorption and light harvesting efficiency via light scattering TiO2 particles. The detail morphological, optical, absorption and photovoltaic properties would be discussed. |
