Low temperature sintered TiO2 porous layer
Contents
The methods
Conventionally it requires 450˚C to 500˚C to sinter the TiO2 porous layer which functioning as the photo-electrode in dye sensitized solar cell. The high sintering temperature eliminates the participation of textile or plastic substrates in the DSSC making. Therefore, a low temperature sintering method to make the TiO2 layer is widely discussed. There are two attempts are introduced here: 1, Optical sintering by the UV exposure of mercury tube. 2, Make the TiO2 paste with the HCL additive and ethanol.
UV sintering
- 150˚C sintering with UV assist
experiment setting.
temperature measuring.
The sample is put on a heat plate and exposed under the UV mercury tube.
The result
Low temperature sintering TiO2 paste made with HCL
Firstly, a commercial low temperature sintering TiO2 purchased from a Japanese company peccell was used. This TiO2 paste costs JPY110,000 for 100 grams.
