Degradation of the solar cell dye sensitizer N719. Preliminary building of the dye-sensitized solar cells

摘要

In this thesis, we investigated the effect of some factors on degradation of the solar cell dye N719 with laser light. The anatase/rutile ratio of TiO2, oxygen amount and other types of TiO2 was studied on degradation of N719. Dark degradation of N719 was also investigated. We also tried some methods of HPLC-UV-MS in identification of degradation products. Characterization of many TiO2 samples was measured. Finally, we have tried to build some dye-sensitized solar cells in our lab.
