中文摘要： 现代电子元器件朝高效能和低消耗方向发展，这对能量供给系统提出了更高要求。将太阳能电池和锂离子电池相结合的能量转化/存储一体化器件，可消除从能量转化到存储过程中的传递能耗，并可实现利用可再生清洁能源自充电，是未来理想的能量供给系统，因此当前备受关注。然而，此一体化器件需要多个太阳能电池组件串联以驱动锂离子电池工作，这大大增加了其复杂性而降低了可行性。.本申请项目在前期对TiO2纳米管阵列在管状金属Ti基体生长研究基础上，提出利用管式金属Ti基体，设计和制备高集成、简洁化的新型能量转化/存储一体化器件结构：在Ti管外表面，利用喷涂法制备一系列串联有机太阳能电池，以产生足够电压驱动管内基于TiO2纳米管阵列的锂离子电池。研究其性能随太阳能电池和锂离子电池组件参数的变化规律，分析影响一体化器件特性的关键物理参数以及影响机制,建立管式一体化器件的设计方法与准则，为新一代管式一体化器件的应用奠定基础。

英文摘要： The development of modern electronics aims toward high efficiency and low consumption. This puts forward high requirements of the energy supply system. An integrated energy system combining solar cells and lithium ion batteries can eliminate the energy consumption during transport between energy conversion and storage compartments. It is possible to charge itself by making use of renewable clean energy, which is the current focus as a promising future energy supply system. However, the integrated device requires multiple solar cell components to drive the lithium batteries, making it more complicated and less feasible. . Based on the previous study on the growth of TiO2 nanotube arrays on a titanium tubular electrode, this proposal aims to design and fabricate a highly integrated and facile device of energy conversion/storage: a number of organic solar cells are prepared at the outer surface of the tubular electrode by spray coating to charge the lithium ion battery inside the electrode with TiO2 nanotube arrays as the anode. This project will investigate the varying trend of the integrated device property with the component parameters of solar cells and batteries, and analyse the key parameters and mechanism affecting the device property. The project will establish a design method and principle for the tubular integrated devices, consolidating the basis for the application of next generation integrated devices.
