With the increasing consumption of energy and the depletion of fossil fuels, finding an alternative energy source is critical. Solar energy is one of the most promising energy sources and solar cells are the devices that convert solar radiation into electricity. Currently, the most widely used solar cell is based on p-n junction formed with crystalline silicon materials. While showing high efficiency, the high fabrication cost limits its broad applications. Dye sensitized solar cell (DSSC) is a promising low-cost alternative to the Si solar cell, but its efficiency is much lower. Improvements in materials and interfaces are needed to increase the DSSC efficiency while maintain the low cost. In this thesis, three projects were investigated to optimize the DSSC efficiency and reduce the cost. The first project is to optimize the TiO[subscript]2 barrier layers on Fluorine-doped Tin Dioxide (FTO) surface. Two preparation methods, i.e. TiCl[subscript]4 solution treatment and thermal oxidation of sputtered Ti metal films, were employed and systematically studied in order to minimize electron-hole recombination and electron backflow during photovoltaic processes of DSSCs. TiCl[subscript]4 solution treatment method was found to create a porous TiO[subscript]2 barrier layer. Ti sputtering method created a very compact TiO[subscript]2 blocking layer. Two methods showed different characteristics and may be used for different DSSC studies. The second project is to reduce the DSSC cost while maintaining the efficiency by replacing the expensive Pt counter electrode with a novel vertically aligned carbon nanofiber (VACNF) electrode. A large specific electrode surface area (~125 cm[superscript]2 over 1 cm[superscript]2 geometric area) was obtained by using VACNFs. The relatively high surface area, good electric conductivity and the large numbers of active graphitic edges existed in cone-like microstructure of VACNFs were employed to improve redox reaction rate of I[subscript]3[superscript]-/I[superscript]- mediators in the electrolyte. Faster electron transfer and good catalytic activities were obtained with such counter electrodes. The third project is to develop a metal organic chemical vapor deposition (MOCVD) method to coat TiO[subscript]2 shells on VACNF arrays as potential photoanodes in the DSSC system in order to improve the electron transfer. Fabrication processes were demonstrated and preliminary materials were characterized with scanning electron microscopy and transmission electron microscopy. MOCVD at 300 mTorr vapor pressure at 550° C for 120 min was found to be the optimal condition.

The study is to investigate the two parts of working electrode and counter electrode. In the first part, the anatase TiO2 nanoparticles and hollow spherical were prepared by hydrothermal method, then use screen printing method to fabricate active layer, blended layer and scattering layer to compose the optimization multiple structures working electrode. This multiple structures not only can increase the dye adsorption but also the light scattering ability, performance of the current density 17.49 mA/cm2, and the efficiency was 9.24%. In the second part, the fabrication of platinum (Pt) counter electrodes was performed with various preparation methods and different materials. Counter electrodes such as Pt/graphene via screen printing and Pt by sputtering was utilized in DSSCs and their photovoltaic performances were compared. Due to the higher dispersibility of add graphene in the Pt could increased catalytic ability, the Pt/graphene device exhibited a lower electron transport resistance (R1) than Sputter Pt CE device as observed from electrochemical impedance data. The Pt/graphene device exhibited a higher current density 14.20 mA/cm2 and the efficiency of 7.88% , which was relatively higher than Sputter Pt CE (23.90%). The optimum conditions for the two parts of working electrode and counter electrode, the performance of current density 18.52 mA/cm2, and the efficiency can be reached 9.52%.

This dissertation can be qualitatively divided into three parts, (i) influence of 1-D carbon nanotubes and 2-D graphene nanosheets carbon, (ii) mesocarbon microbead-based and (iii) graphene nanosheet with different oxidation levels as counter electrodes for dye-sensitized solar cells. The resulting carbon counter electrodes were characteried by XRD, FE-SEM, HR-TEM, Solar simulator and IPCE test. (i) 1-D carbon nanotubes and 2-D graphene nanosheets carbon as counter electrodes This study examines the dye-sensitized solar cells (DSSCs) equipped with 1-D carbon nanotubes (CNTs) and 2-D graphene nanosheets (GNs) carbon counter electrodes. Imperfect defects were attached to the sidewall or both the ends of the CNTs, and the edges of the GNs were analyzed by X-ray diffraction and Raman spectroscopy. When compared with the GN-based counter electrode, CNT-based counter electrodes showed a better improvement in the incident photon-to-current efficiency and power conversion efficiency of the cells. This enhancement of cell performance can be attributed to the combination of CNT network and spherical graphite bottom layer, favoring dye adsorption, catalytic redox activity, and 1-D charge-transfer path length. Such carbon configuration as counter electrode provides a potential feasibility for replacing metallic Pt counter electrodes. (ii) Mesocarbon microbead-based as counter electrodes The dye-sensitized solar cells (DSCs) equipped with mesocarbon microbead (MCMB)-based counter electrodes were explored to examine their cell performance. Three types of nanosized additives including platinum, carbon nanotubes (CNTs), and carbon black (CB) are well dispersed and coated over microscaled MCMB powders. In the design of the counter electrodes, the MCMB graphite offers an excellent medium that allows charge transfer from the ITO substrate to the dye molecule. The active materials such as Pt, CNT, and nanosize CB act as an active site provider for the redox reaction. Among these counter electrodes, the DSCs fabricated with CB electrode exhibits the highest power conversion efficiency. This improved efficiency can be attributed to the fact that the CB nanoparticles not only offer a large number of catalytic sites but also low charge transfer resistance, facilitating a rapid reaction kinetics. Such design of carbon counter electrode has been confirmed to be a promising candidate for replacing Pt electrodes. (iii) Graphene nanosheet with different oxidation levels as counter electrodes This study examines the performance of dye-sensitized solar cells (DSCs) equipped with graphene nanosheet (GN) counter electrodes with different oxidation levels. A thermal deposition is adopted to adjust O/C atomic ratio and surface oxygen functionalities on graphene sheets. With decreasing the O/C ratio, the GN electrode displays high catalytic activity toward the I3¯/I¯ redox reaction and lower charge-transfer resistance, analyzed by cyclic voltammetry and electrochemical impedance spectroscopy. The DSC fabricated with GN counter electrode also offers an improved incident photon-to-current efficiency and power conversion efficiency, in comparison with that equipped with graphene oxide electrodes. This improvement of cell performance could be attributed to the fact that the GN with 2-dimensional crystal of sp2 carbon and π electrons, acts as a semi-metal or a zero-bandgap semiconductor with remarkable high electron mobility.

Because of high price of Pt noble metal, it is necessary to investigate new materials to replace the Pt as counter electrodes (CE) of DSSCs for industrial production. In this study, the cobalt sulfide nanomaterials with nanoflake arrays, mesoporous thin films and mesoporous nanotube arrays, respectively, are successfully fabricated on FTO coated glass by difference synthesis technologies including hydrothermal synthesis of Co(OH)2, mesoporous Co3O4 formation from cobalt-chelated chitosan, selective etching of ZnO sacrificial templates and ion-exchange reaction (IER). The mesoporous Co3O4 structures composed of the Co3O4 nanoparticles possess the high surface area and take advantage for further removal of templates and ion-exchange reaction. The mesoporous CoS2 structures are prepared by substitution of S2- for O2- after the IER at 90 ℃ for 4 hours. Morphologies and crystal structures of the CoS2 structures were characterized by SEM, TEM and XRD analyses. Their electrocatalytic properties were determined by electrochemical analyses including cyclic voltammetry (CV) measurement and Tafel polarization. Among all cobalt sulfides, the DSSC assembled with mesoporous CoS2 nanotube array CE achieved a highest power conversion efficiency of 6.13% under AM 1.5 condition, which was comparable to that of 6.04% for the DSSC with Pt CE. It indicates that the mesoporous CoS2 nanotube array can be a low-cost and efficient alternative for the reduction of electrolytes in DSSCs.
