碩士 === 國立東華大學 === 光電工程學系 === 102 === Dye-sensitized solar cells(DSSCs) is a kind of solar cell ,that have the advantages be simple process, low cost and high power efficiency. In this study have three part .First, we applies graphene to counter electrodes for DSSCs. And then, we investigated the characteristics of current-voltage curve, impedance spectroscopy and external quantum efficiency. And we use the Raman & XPS measurement to identify the quality of the graphene sample. Then, using different method to add graphene in platinum eletrodes. Discussion the study of decrease platinum. Second, we use electrochemical deposition to make platinum in this study. To compare the platinum for using doctor blade. And we investigated the characteristics of current-voltage curve, impedance spectroscopy, cyclic voltammetry, FE-SEM and external quantum efficiency. Finally, we use HCl/ACE solution to acid treat TiO2 that improves cells.And we investigated the characteristics of current-voltage curve, impedance spectroscopy, external quantum efficiency , electron lifetime, electron transit time and collection.
