Photovoltaic Performance in the Dye-Sensitized TiO2 Electrode using HPC Binder |
| 초록 |
Titanium oxide based dye-sensitized solar cells (DSSC) was fabricated by the use of hydropropylcellulose (HPC) as binder. The formation mechanism of HPC-modified TiO2 films was studied by FTIR analysis of the sols. It was revealed that HPC anchors on the surface of TiO2 colloid. The action between the polymers decides the distribution of TiO2 colloid in the sol. Transmission electrical microscopy (TEM) and scanning electrical microscopy (SEM) showed that the particle size of TiO2 decreased and the microstructure of the film became loose with the addition of HPC, reaching an optimum when the concentration of HPC was 5×10−3 g/g sol. Further addition of HPC made the microstructure became dense. With the increase of the concentration of HPC binder to treat TiO2 electrode the fill factor (FF) of DSSC increase, the short-circuit current (Isc) decreases, the open-circuit voltage (Voc) increase. Using HPC binder is advantageous for the adsorption to molecules and enhancement of the photoelectric performance of TiO2 electrode. |
