英文摘要： The dye-sensitized solar cells (DSC) are the novel thin film solar cells which converts solar energy directly to electricity. DSC possesses great application prospect due to the simple fabrication technology and the abundant raw material. The urgent key question is how to clarify the dynamic process of DSC and further improve the light-electric conversion efficiency of large-scale DSC module by designing reasonable electrode structure. Based on present study and combined with the theoretical simulation and experiment research, this project starts from the improvement of the DSC collection efficiency to investigate the joule loss on the conductive layer of substrate and the metal grids, and to analyze how the inner series resistances affect collection efficiency and photovoltaic performance of DSC，so that it can explore the change law of photovoltaic performance with the different material characteristics and reveal the mechanism of electron collection loss of DSC. Through the mutual balance of the illumination-area loss and the joule loss in solar cells, this project also clarifies the effect of electrode design on the photovoltaic performance of DSC and setups the theoretical model that provides theoretical instruction for electrode design to reflect the photovoltaic performance of DSC. We are eager to obtain c
