Semiconductor Nanostructured Materials for Next Generation Photovoltaics
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, and their 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 counterelectrode.
