发展新型光电转换材料一直倍受青睐，考虑能源和环境两个方面，设计全水相操作路线来构筑更加清洁环保的太阳能电池是非常有意义的。本项目主要研究内容是基于水相合成纳米晶、碳基荧光纳米点和高载流子迁移率的水溶性共轭聚合物材料，建立相关杂化与复合方法；通过调节聚合物与纳米点之间的相互作用，调控本体微相分离实现双连续相互穿结构；通过模板诱导组装构筑有序微纳结构，实现载流子的高效传输；通过在界面构筑减反射有序微结构和利用等离子共振来增强光的吸收，进一步提高器件光电转换效率。研究目标是实现以聚合物杂化材料为活性层的高效太阳能电池、红外光探测、LED等光电转换器件的绿色制备。

In recent years, development of novel photoelectric materials has drawn increasing attentions due to the severe challenges from energy and environment. In this sense, it's significant to design environment-friendly solar cells from aqueous-solution-processing approaches. The research contents of this project can be divided as follows: First, we want to establish methods of fabricating polymer hybrid composites based on the preparation of aqueous nanocrystals, luminescent carbon dots and water-soluble conjugated polymers with high carrier mobility. Additionally, we want to achieve bicontinuous pathways by controlling the interaction and phase separation between polymers and nanodots. After that, we want to construct the ordered heterojunction for effective carrier transport through template-induced assembly. Finnally, we want to strengthen the absorption by constructing anti-reflection structure and taking advantage of plasmon resonance, thus further improving the device performance. This project aims to achieve the environment-friendly fabrication of efficient photoelectronic devices, such as solar cells, infrared light detector, and light emission diodes, with the polymer hybrid materials as active layers.
