By the analysis of the titanium dioxide and carbon nanotube thin film electrodes, the effects of the electrodes on the interfacial redox reaction were examined. By testing the processing and compositions of the dye-sensitized solar cells, the most efficiency processes were found in this study.pply the titanium dioxide photo electrodes on the dye-sensitized solar cells, it need to adsorb a layer of dyes to increase the conductivity of electrons. This research dips the TiO2 electrodes in TCPP solution with 0.2mM DCA in a long time. We are coating ITO counter electrodes with platinum about 50 nm and with silver about 100 nm, respectively.he open circuit voltage increase because of isolation the titanium dioxide with iodide ions after addition of the ions liquids. Besides, added DCA into the TCPP solution let electrons easily excited to the LUMO level of the titanium dioxide therefore increase both of photo circuits and photo voltages. The counter electrodes with carbon nanotubes are more stable than metal counter electrodes due to the carbon nanotubes had an excellent chemical resistance although the efficiency did not higher than the cell with metal counter electrodes.bout the composition of the solar cell, the best performance solar cell was dips in TCPP solution with 0.2mM DCA, the electrolyte injected with 0.5M TBP . On an incident light intensity of 1.5 mW/cm2, it corresponds to an overall power efficiency of 2.15%.Finally we get a best efficiency about 7.63% with the best processing in silver counter electrode, and 2.34% in CNT counter electrode respectively.Chinese abstract Inglish abstract IIontents IVigures VIables VIIIhapter 1 Introduction 1-1 Preface 1-2 Type of the solar cell 3-2-1 Silicon solar cell 3-2-2 Membrane solar cell 4-2-3 Non-crystalline silicon solar cell 5-2-4 CuInGaSe2 solar cell (CIGS)(4) 6-2-5 Dye-sensitized solar cell 7-3 Research purpose 9hapter 2 The principle and review 11-1 Introduction of semiconductor 11-2 Principle of dye sensitized solar cell 18-3 The efficiency curve of solar cell 21-4 Dye 35-4-1 Polypyridyl 35-4-2 Porphyrin 41-5 Electrolyte 45-6 Carbon nanotube 47hapter 3 Instrument and experiment 51-1 Instrument and equipment 51-2 Medicines 52-3 Preparing titanium dioxide membrane electrode 53-4 Preparing the carbon nanotube electrode 54-5 Preparing the platinum and silver electrodes 58-6 Measure titanium dioxide membrane 59-7 Measure the wavelength of the dye 59-8 Produce the components of the dye sensitized solar cell 60-9 Test the value of resistance of conductive plate 60-10 Analysis on surface with SEM 61-11 Analysis on surface with AFM 62-12 Diffraction analysis of the X-rays 63-13 Surface analysis with TEM 65hapter 4 Result and discussion 66-1 Analysis of titanium dioxide powder 66-2 The influence of processing of the titanium dioxide membrane 70-3 The influence of dye that add DCA 73-4 The influence of the ionic solution adds in the electrolytic liquid 75-5 The influence on efficiency of different electrodes 77-6 Ultraviolet-visible light spectrum analysis (UV-VIS) 80-7 The influence under different light intensities 82hapter 5 Conclusion and suggestion 85-1 Conclusion 85-2 Suggestion 87hapter 6 References 88application/pdf2195898 bytesapplication/pdfen-US染料敏化加熱噴霧紫質衍生物奈米碳管dye-sensitizedspray pyrolysisporphyrincarbon nanotubethesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/183095/1/ntu-97-R94549032-1.pdf
