Functional polymers and nanocrystals are promising building blocks for advanced materials and devices. In this talk, I will present our efforts on nanostructured functional materials from synthesis, self-assembly to solar energy applications. Two studies will be discussed: semiconductor conjugated polymer-quantum dot (CP-QD) and conjugated polymer-quantum rod (CP-QR) nanocomposites via directly grafting CP onto QD and QR surface by Heck coupling and click reaction for potential applications in nanohybrid solar cells; and low-cost, high-efficiency dye-sensitized solar cells (DSSCs) through the use of nanostructured TiO2 (e.g., nanotubes and nanoflowers) as photoanode, and earth abundant, environmentally friendly quaternary semiconductor copper zinc tin sulfide (CZTS) as counter electrode.
