In this study, we study the synthesis of TiO2 nanocrystals with specific crystal facet on their surface by a novel soft chemical process, dye adsorption behavior on the specific crystal facet, relationship between the dye adsorption behavior and the performance of dye-sensitized solar cells (DSCs), and development of high performance DSCs by controlling the crystal facet of the TiO2 nanocrystals. We focus on the three points as follows: (1) synthesis of TiO2 nanocrystals with specific crystal facet on surface. Development of high performance DSCs using the TiO2 nanocrystals with controllable facet. (2) Study on dye adsorption and photoelectrons transformation from dye to TiO2 with specific facet by nanostructural and optical characterization. (3) Clarification of the relationship between dye adsorption parameters, adsorption density and constant, and cell performance parameters, short-circuit current density, open-circuit voltage, fill factor, and energy conversion efficiency.

在这项研究中，我们通过一种新型的软化学过程，在特定晶体上的染料吸附行为，染料的吸附行为与染料敏化的太阳能细胞（DSC）的性能之间的关系以及高性能DSC的发展，通过控制高性能DSC的发展，通过控制染料敏化的表现，通过控制高性能DSC的染料吸附行为和通过控制Crystal the Crystar tio2 Nan tio2 Nan tio2 Nan的发展来研究TiO2纳米晶体与表面上特定的晶体面的合成。我们专注于以下三个点：（1）TIO2纳米晶体的合成，表面具有特定的晶体。使用具有可控面的TIO2纳米晶体开发高性能DSC。 （2）研究染料吸附和光电子从染料转化为TiO2的研究，并通过纳米结构和光学表征特定方面进行研究。 （3）阐明染料吸附参数，吸附密度和常数以及细胞性能参数，短路电流密度，开路电压，填充因子和能量转换效率之间的关系。
