英文摘要: The project is going to perform the synthesis and photoelectric property investigation of nanomaterials, aim at fabricating the solid state solar cell by combining the quantum dot and nanotube array. Long and ordered TiO2 nanotube array on transparent FTO glass substrate will be synthesized through electrochemical anodization. The present QDSSC will use TiO2 nanotube array as photoanode, semiconductor quantum dot as light absorber, and Spiro-OMeTAD as solid state electrolyte. We will optimize the preparation of the materials, inrease the loading of QD in the TiO2 nanotube, optimize the receipt of the electrolyte and filling of the electrolyte in the TiO2 nanotube, in order to enhance the photovoltaic performance. The EIS, IMPS, IMVS will be performed to analyze the electron transport and recombination and discuss their influences on the photovoltaic performance in order to understand the mechanism and which will indict the fabrication of high efficiency QDSSC. Hence, this project has strong novelty, important research value and various application potentials.
